Why Cover Grass Seed After Planting?

You’ve just spent time, money, and effort prepping your lawn, carefully sowing grass seed in the bare or thin spots. Now it’s time to nurture those delicate seeds to grow into a lush, green lawn. But before you sit back and wait for the grass to germinate, it’s crucial to add a light covering over the planted seeds.

Uncovered grass seed is vulnerable in several ways:

Seeds can be washed away by rain or irrigation – Without something to anchor them down, sprinkler water or heavy rain can displace seeds, sweeping them off to the side or burying them too deeply to properly germinate.
Seeds are prone to drying out when uncovered – Moisture is essential for seeds to germinate and seedlings to establish. Just a day or two of drying on top of bare soil can kill tender new grass before it even has a chance to grow.
Soil temperature fluctuations can inhibit germination – Grass seeds require consistent, warm soil temperatures around 60-90°F to germinate. Temperature swings between night and day on bare ground can slow or prevent seeds from sprouting.
Birds and other wildlife love to eat uncovered seeds – Leaving seeds exposed is an open invitation for birds, squirrels, raccoons, and other critters to feast on your grass seed smorgasbord. Protecting seeds discourages freeloaders.

How Coverings Shield Grass Seed

Seed coverings act as a protective barrier, creating an optimal microclimate for your grass to germinate and take root. The right cover moderates soil temperature and retains moisture while allowing sufficient air circulation. It literally shelters those vulnerable seeds to give them a better shot at survival.

Here’s a more in-depth look at how seed coverings benefit new grass:

Anchors seeds in place – Covering materials like straw, peat moss, or shredded leaves add gentle weight to keep seeds and soil from shifting. This prevents seeds getting washed out of place or buried too deeply.

Holds in moisture – Coverings minimize evaporation, keeping seeds moist long enough to sprout and establish. Some options like peat moss or fabric covers are especially moisture-retentive.

Maintains consistent soil temperature – Natural coverings insulate seeds from extreme temperature swings, allowing them to germinate in their ideal 60-90°F soil temperature range.

Allows sufficient air circulation – While holding in heat and moisture, coverings still permit enough airflow for seeds to breathe and sprout. Stagnant air can encourage fungal growth.

Blocks sunlight to deter weeds – Covering your seeds gives them a head start on germination while blocking sunlight from reaching potential weed seeds. Less light means fewer weeds.

Discourages hungry animals – Protective materials form a physical barrier and camouflage grass seeds, making it much harder for birds and other wildlife to find seeds and eat them.

Suppresses fungal diseases – Maintaining stable moisture and soil temperatures minimizes conditions conducive to fungal growth. Healthy grass quickly outgrows susceptibility to damping off diseases.

Reduces erosion – Covering materials reinforce the seeded top layer of soil against wind, rain, and irrigation water forces that can erode seeds away.

The Cost of Skipping Seed Covers

Now that you know all the ways seed coverings help new grass thrive, you’re probably convinced it’s worth taking this simple extra step. But what actually happens if you don’t cover your grass seed?

Unfortunately, the outlook is not so good for uncovered seeds. They are incredibly vulnerable to several threats:

Up to 90% of seeds may fail to germinate or survive past the seedling stage.
Heavy rainfall can displace seeds, depositing them in random clumps with poor germination rates.
Irrigation runoff can wash seeds completely off site down slopes and drainage areas.
Alternating wet and dry periods often prove fatal to tender sprouts.
Birds can decimate exposed seeds in no time, leaving bare patches.
Damping off fungal diseases spread rapidly through unprotected new seedlings.
Hot sunlight bakes and kills grass embryos on bare ground with no insulation.
Frost heave over winter uproots newly sprouted seeds as soil freezes and thaws.
Harsh winds erode and carry away topsoil along with unanchored seeds.
Weeds fill in empty spaces left by seeds that didn’t make it.

Reseeding bare patches is no fun, not to mention the wasted time, effort, and money from grass seed lost to improper planting. A minimal investment in protective coverings repays itself many times over in lush, thick grass.

Materials to Cover and Protect Grass Seed

Now that you appreciate all the benefits of covering your seed, let’s look at some of the most common protective materials used:

Straw – This inexpensive seed covering is readily available at garden centers and farm supply stores. Straw from oats, wheat, and barley works well to safeguard grass seed. Apply a light 1/4″ layer.

Peat moss – Preserves moisture excellently, and provides nutrients as it decomposes. Use a thin dusting over seeds. It’s more expensive than straw but also very effective.

Compost – Make sure compost is screened to remove sticks and weed seeds. Compost enhances soil structure and nutrients.

Grass clippings – Fresh clippings can compact and mat, so allow them to dry fully before using as a biodegradable mulch. Adds organic matter to soil.

Shredded leaves – Chop leaves first to prevent matting. Rich in minerals released as the leaves break down. Avoid using whole leaves.

Pine needles – Finely shredded pine needles work well to retain moisture while allowing sunlight through. Too thick of a layer can be acidic.

Landscape fabric – Fabric lets air, water, and light reach seeds while blocking runoff. Keeps seeds moist and protected from birds.

Plastic sheeting – Clear polyethylene plastic raises soil temperature to boost germination. Remove once sprouts emerge to avoid overheating.

Hydromulch/tackifiers – Wood fiber mulches bind to soil with tackifiers to form a moisture-retaining grass seed blanket. Often used on slopes.

Rolled erosion control mats – Geotextile mats hold seed and soil in place on inclines and in channels. Most naturally biodegrade over time.

The ideal seed cover protects your investment in grass seed while promoting vigorous germination and growth. With the seeds safe from harm under a cozy blanket of protective mulch, you’ll spot the first tiny sprouts pushing up through the soil in no time!

Factors to Consider When Choosing a Grass Seed Cover

You want to pick the ideal grass seed cover to create the perfect microclimate for germination and growth. But with so many options for covering seed, how do you decide what’s best? Here are the key factors to consider when selecting a protective mulch or blanket for your grass seed:

Material Cost and Availability

For large areas, material costs can add up. Balancing performance with affordability helps determine the best cover for your specific needs and budget.

Free cover materials – If available, grass clippings, leaves, garden compost, or other on-hand biodegradable materials are the most economical seed covers. However, you’re limited by what you have on site.

Low-cost conventional options – Straw is the tried and true covering that’s inexpensive and easy to source. A bale of straw typically costs $5-$10 and covers 1500-2000 sq ft of seed.

Premium specialized products – Materials like coconut coir, peat moss, or tackifier-bound hydromulch can cost 2-5 times more than basic straw.

Fabric covers – Landscape fabric or erosion control mats are some of the most expensive coverings at $100-200 for enough fabric to cover 1000 sq ft.

Consider how much you need to purchase based on your lawn’s square footage and any reuse potential. For example, straw bales or fabric can be used year after year. You’ll also have to factor in any extra tools or labor required to apply different materials.

Material Properties

The ideal seed cover has the right balance of moisture retention, density, and breathability. Assess whether a material meets the needs of your grass seed:

Permeability – Covers need to allow water, air, and emerging seedlings to pass through easily. Densely packed materials can block moisture and light.

Density – Aim for loose, fluffy covers that insulate without compacting. Dense surfaces smother seeds and prevent sunlight from fueling growth.

Biodegradability – Covers that break down over time add organic matter to soil. Avoid plastic sheeting that must be removed manually.

Texture – Smooth materials like plastic sheeting provide protection without mixing into soil. Rough textures adhere better on slopes.

Acidity – Pine needles and leaves have acidic compounds that may inhibit germination. Grass clippings work well if dried first.

Weed seeds – Use compost, manure, and straw free of seeds to avoid sprouting extra weeds. Screening helps remove contaminants.

Evaluate seed cover characteristics to find the right balance for your conditions. For example, erosion control mats excel on hills but may lack breathability.

Ease of Application

How easily and quickly you can apply different covering materials is another practical consideration:

Loose materials – Straw, peat moss, shredded leaves require careful and even hand spreading. Irregular coverage leaves seeds exposed.

Anchoring – Lightweight loose covers need edges secured with stakes or stones to prevent wind or water displacement.

Rolled materials – Fabric sheets and erosion mats unroll quickly for instant coverage. No special tools needed.

Binders – Hydromulch with tackifiers is spray applied. Binder chemicals secure the mulch layer to the sloped soil.

Removal – Loose covers breakdown over time. Plastic sheeting or landscape fabric must be removed manually once sprouts emerge.

Labor – Determine if you’ll need extra helpers for lifting bales, raking material, and removing plastic covers.

Weather dependence – Damp natural materials or spray-on hydromulch don’t work well in wet, windy conditions when installing covers.

Opt for materials you can easily and correctly apply yourself. Simple and quick installation means your seeds stay protected.

Weighing All the Factors

Choosing seed covers involves balancing multiple considerations:

Weed-free wheat, oat, or barley straw offers an economical, breathable, readily available option for flat areas. Needs even spreading.
Handy free grass clippings should be dried beforehand to avoid matting and rotting. Provides added organic matter.
Peat moss retains moisture excellently but can be expensive. Look for compressed bales to save money.
Compost introduces beneficial microbes and nutrients, but screen thoroughly to remove sticks and seeds first.
Mulched leaves are a free fall byproduct but shred first to improve coverage. Avoid whole leaves.
Durable landscape fabric is pricey but easy to install. Offers excellent seed protection if you don’t mind removing it later.
Plastic sheeting effectively retains moisture and accelerates growth. Must be ventilated and removed to avoid overheating.
Hydromulch with tackifiers adheres nicely on slopes and erodible soils. Requires commercial spraying equipment to apply.

The ideal cover strikes a balance between functionality and practicality based on your specific seeding situation. With so many options, you can keep your grass seed protected and ensure it sprouts successfully!

Recommended Cover Materials for Grass Seed

When it comes to the best covers for protecting grass seed, you have a wide range of options. Each material has its own advantages and disadvantages. Here’s an in-depth look at the top recommended seed covers to consider:

Straw

Straw is the traditional and most popular cover for newly planted grass seed. Readily available and affordable, straw offers great protection for establishing lawns when applied properly.

What types of straw work best?

Wheat straw is readily available and contains fewer weed seeds than other types.
Oat straw decomposes more slowly and is less likely to drift after application.
Barley straw resists mats and clumps well for uniform distribution over seeds.
Avoid hay, which contains more weed seeds that can sprout in your lawn.

Benefits of using straw

Inexpensive at $8-$12 per bale, much less than other covers
Widely available at farm supply and garden stores
Lightweight and breathable to allow new shoots to emerge
Insulates seeds and retains moisture well
Provides effective protection from erosion
Breaks down slowly, continuing to suppress weeds
Can be reused year after year

How to apply straw cover

Spread straw immediately after seeding at a rate of 1-2 bales per 1000 sq ft
Apply an even, light layer about 1⁄4-1⁄2 inches thick to avoid inhibiting growth
Use a lawn rake to distribute straw evenly without clumping
Gently tamp down straw to anchor it and maintain contact with the soil
Mist seeded area lightly to help adhere straw
Secure edges with stakes or stones to prevent wind displacement

Potential drawbacks

Can harbor unwanted grass and weed seeds if not from a reliable source
Needs shaking up and evening out to avoid bare patches
Requires securing the edges to prevent it blowing away
Eventual breakdown can lead to thinner coverage over time

Peat Moss

Peat moss offers superior moisture retention, helps moderate soil temperatures, and adds beneficial organic matter as it slowly decays.

Key properties of peat moss

Absorbs up to 20 times its weight in water, releasing it slowly to seeds and roots
Consists of decomposed bog plants including mosses, sedges, shrubs and grasses
Acidic pH of 3.5-4.5 helps prepare soil for grass growth
Provides nutrients including nitrogen, phosphorus and potassium
Dark color absorbs warmth from sunlight to enhance germination
Lightweight structure avoids compacting and smothering young plants

How to use peat moss as a seed cover

Work peat moss into soil first to improve moisture retention, then apply a thin 1⁄8-1⁄4 inch layer over seeded areas
Break up compressed bales and loosen peat moss into a fluffy consistency before spreading
Mix in a starter fertilizer when incorporating peat moss into soil
Mist peat moss after application to prevent excess dust and evenly adhere particles
Monitor moisture levels – peat moss dries out faster than other mulches

Benefits of peat moss cover

Significantly increases soil moisture retention
Moderates soil temperature fluctuations
Provides useful organic materials, humic acids, and micronutrients
Light texture avoids compacting or matting over seeds
Naturally resists weed growth and seed germination

Potential limitations

More expensive than straw, compost or other seed covers
Dries out faster than other cover materials
Can blow away before adhering if application is too thick
Needs rewetting to redistribute if it dries out unevenly
Unsustainable harvesting damages fragile wetland ecosystems

Compost

Screened compost offers nutrients and organic matter to nourish developing seedlings. But make sure it’s free of weed seeds that could sprout in your lawn.

How to prepare compost as a seed cover

Use well-finished, fully decomposed compost to avoid robbing nitrogen from tender grass
Screen thoroughly to remove sticks, rocks and debris
Test that compost pH is between 5.5-7.5, ideal for grass growth
Ensure compost is weed-seed-free by heating to 140°F+ during production
Mix compost into soil before seeding to improve fertility and water retention

Applying compost cover over seed

Spread 1⁄4-1⁄2 inch layer evenly over seeded areas
Take care to not bury seeds more than 1⁄4 inch deep
Gently tamp to adhere compost particles without compacting layer
Mist seeded areas after application to moisten and set compost
Reapply additional thin layers of compost as first layer decomposes

Benefits of compost cover

Slow release source of essential nutrients for grass plants
Improves moisture retention, porosity, and tilth as it enriches soil
Introduces beneficial microbes and organic compounds
Provides protection from erosion while allowing shoots to emerge
Helps suppress weed germination and maintain even soil temperatures

Watch out for

Possible weed seeds in unfinished or unscreened compost
Nutrient and pH variability between different batches
Tendency to dry out faster than wood or straw mulch
Needs reapplication after watering in for sustained protection
Care needed to avoid burying seeds if applied too thickly

Grass Clippings

Recycling freshly cut grass clippings offers a convenient nutrient-rich protective cover. Just be sure to let them dry thoroughly first.

Grass clipping tips

Collect clippings after mowing and allow to fully dry in the sun
Spread thin layers 1⁄4 inch deep or less to avoid matting
Use old clippings first before they decompose and lose efficacy
Spot treat any weeds before they go to seed and contaminate clippings

Applying grass clippings over seed

Distribute dried clippings immediately after seeding
Take care not to bury seeds deeper than 1⁄4 inch
Gently water after applying to settle clippings without displacing seeds
Reapply additional light layers as the first layer of clippings decomposes

Benefits of grass clippings

Free, readily available organic material from mowing
Contains nitrogen, phosphorus and potassium to feed new seedlings
Light texture avoids overly compacting or smothering seeds
Improves soil structure and nutrient content as clippings break down
Convenient to collect and spread with minimal tools or effort

Downsides to consider

Fresh wet clippings can clump together inhibiting growth
Rapid decomposition means frequent reapplication is needed
Weed or herbicide residue in clippings may hinder grass
Inconsistent nutrient content depending on grass species and age
May harbor lawn diseases requiring careful inspection before using

Leaves

Fallen leaves from trees in your landscape are a free seed cover alternative. Reduce matting and compaction by shredding or chopping leaves first.

Preparing leaves for grass seed

Use leaf mulching mower to shred them finely as you collect leaves
Run over already fallen leaves with mower to achieve smaller pieces
Avoid whole, unchopped leaves that can mat together inhibiting growth
Mix shredded leaves into soil before seeding to increase organic matter

How to apply leaf mulch over seed

Spread a 1⁄4–1⁄2 inch layer over freshly planted grass seed
Mist leaves lightly to moisten and help them adhere to the soil surface
Reapply additional thin layers of shredded leaves as first layer decomposes
Chopped leaves are less prone to blowing away than whole leaf layers

Advantages of leaf cover

Abundant free source of mulch in fall when seeding cool-season grasses
Shredded leaves allow sunlight, air, and water penetration to seeds
As leaves break down, they contribute valuable nutrients and organic matter to the soil
Helps insulate soil and moderate soil moisture and temperature

Considerations

Whole, non-shredded leaves easily blow away and can mat over seeds
May harbor insect eggs, fungus and other pathogens requiring heat or chemical treatment
Allelopathic compounds in some leaves inhibit nearby plant growth
Provides less erosion control on slopes than straw, peat moss or fabric

Landscape Fabric

Landscape fabric offers a protective physical barrier that retains moisture while allowing air and light through. Convenient to work with, but more costly than other covers.

Working with landscape fabric

Choose lightweight, porous fabric for seed covering to prevent matting tender shoots
Roll fabric out over freshly seeded areas, securing edges with stakes or stones
Ensure fabric remains in close contact with soil so wind doesn’t dry seeds out
Water seeded areas sufficiently before covering to supply moisture from below
Remove fabric once grass reaches 2-3 inches tall to avoid inhibiting growth

Pros of landscape fabric

Permits sunlight, air, and water through while blocking erosion and pests
Holds in moisture and insulates soil to enhance germination
Quick and easy installation without tools – just roll out and secure edges
Anchors seeds and topsoil in place, especially helpful on slopes
Can be reused for years when stored properly away from sunlight

Things to watch for

Relatively expensive, but cost may balance out with multi-year reuse
Improper extended use can constrain seedling growth when left on too long
Loosely installed fabric can billow in wind and dry out seeds
Removing installed fabric can disturb newly sprouted grass
Synthetic fabrics don’t improve soil structure or add organic matter as they break down

Clear Plastic Sheeting

Clear polyethylene plastic sheeting seals in moisture and accelerates soil warming to boost grass seed germination. But it must be ventilated and removed on time.

How to use plastic sheeting over seed

Roll plastic out over smoothly raked, seeded soil
Weigh down the edges with stones or U-shaped garden staples
Maintain close ground contact to retain moisture without drying wind pockets
Use thin 4-6 mil plastic for easier penetration by new grass shoots
Ventilate plastic by lifting periodically to allow gas exchange
Remove plastic as soon as seeds begin to sprout to avoid overheating

Benefits of plastic sheeting

Seals in soil moisture and prevents seed washout and displacement
Warms soil temperatures up to 5-10°F to enhance germination
Blocks sunlight from reaching potential weed seeds
Prevents birds from spotting and eating freshly planted grass seed
Low cost and widely available from hardware/home improvement stores

Watch out for

Heat buildup can cook tender shoots if left on too long
Condensation and moisture pooling under plastic can lead to mold
Improper venting causes low oxygen and high carbon dioxide levels
Must be promptly removed once seeds germinate
Non-biodegradable and must be disposed of responsibly after use

Weighing the Pros and Cons

As you can see, each seed cover has particular strengths and weaknesses. Lightweight, permeable materials like straw, peat moss, shredded leaves or grass clippings are good general use options. For wet conditions, peat moss and landscape fabric shine. On slopes, erosion control mats and fabrics paired with mulch excel.

The ideal cover depends on your specific conditions and seeding objectives. Selecting the right protective material saves your grass seed investment while giving your lawn the best possible start. With the proper cover, your grass will thrive and fill in bare patches quickly!

How to Apply Grass Seed Covers

You’ve chosen the ideal protective cover for your grass seed – now it’s time to install it correctly for the best results. Proper application methods are key to get full value from seed covers. Follow these guidelines to spread covers effectively:

Prepare the Seedbed

Before spreading any cover, ensure your seedbed has good contact with the soil below:

Break up and rake soil to a depth of 3-4 inches removing debris
Level and lightly firm the seedbed so seeds make consistent contact
Moisten soil if dry so water is wicked up to seeds from below
Spread seed evenly according to package directions without burying too deep
Consider rolling seeded areas lightly to gently press seeds into soil surface

This gives grass seeds the ideal germinating environment right from the start.

Spread Covers Evenly in Thin Layers

Uneven covers leave seeds exposed in bare patches. Aim for uniform distribution:

Apply most dry covers like straw, peat moss or compost in 1⁄4 to 1⁄2 inch layers.
Avoid using thicker layers that can smother seeds or constrain shoots.
Spread materials slowly and systematically to prevent bare spots with no coverage.
Use a drop or broadcast spreader for materials like peat moss to ensure even application.
Follow up by gently raking covers to break up clumps and fill in thin areas after spreading.

Thin layers allow sunlight, water and air to pass through easily to seeds and seedlings below.

Cover Seeds Immediately After Planting

For the best protection, install covers promptly after seeding:

Covering too early can allow uncovered seeds to dry out, blowing away, or becoming bird food.
But don’t leave seeds exposed for long either. Get covers down within a few hours, sooner if windy.
If an unexpected delay occurs, mist seeded areas lightly to keep seeds from drying out before covering.

Immediate protection seals in moisture critical for the initial stages of germination. It also prevents displacements that ruin even coverage.

Secure Cover Edges from Displacement

Unsecured covers easily shift from wind and rain runoff:

Anchor edges of light materials like straw, peat moss or compost with stones, staples or stakes.
Weighing down perimeter edges prevents getting underneath and blowing the covers away.
For plastic sheeting, use Fabric Staples, U-pins or carefully placed rocks for even perimeter contact.
On slopes, run fabric covers and blankets horizontally across inclines, securing at least every 3 feet.

Taking a little extra time to properly fasten covers avoids wasted efforts and materials from wind-blown mulch and erosion.

Remove Covers at the Right Time

Leave temporary covers on for the shortest effective duration:

Plastic sheets should be removed as soon as seeds begin to sprout to prevent overheating tender shoots.
Lightweight mulches like straw and peat moss can be removed once grass growth is 1-2 inches tall and reasonably established.
Landscape fabrics can be taken off a bit sooner once sprouts pass through the material and reach 2-3 inches.
Erosion control mats may take 30-90 days to naturally biodegrade depending on material.

Balancing protection of young plants with freedom to grow determines optimal removal timing.

Allow Natural Covers to Break Down Slowly

Covers made of natural materials gradually decompose:

Materials like straw, leaves, compost and grass clippings can be left in place after removing fabrics/plastic sheeting.
Their gradual decomposition continues releasing nutrients and organic matter into the soil.
As layers thin out over weeks, reapply supplemental mulch 1⁄4 inch deep for sustained benefits.
By the first mowing, biodegradable covers will have largely broken down.

Natural mulches don’t need removal – just gradual renewal to prolong their advantages.

Follow Application with Gentle Watering

Watering after application adheres and activates covers:

Mist seeded areas lightly to moisten and help mulch particles adhere without displacing them.
Gentle sprinkling settles materials into consistent contact with the soil and seeds.
Control water volume and flow to prevent washing away lightweight covers.
Follow up with consistent watering to keep seeds and growing grass hydrated.

Moistening bonds covers to soil while stimulating seeds to utilize the warm, moist environment.

Avoid Covering Mistakes

Here are some key errors to avoid when applying seed covers:

Leaving seeds exposed for too long before covering
Allowing covers to blow away in windy weather
Applying covers too thickly and inhibiting growth
Letting fabrics billow away from soil drying out seeds
Using cover materials contaminated with weed seeds
Leaving plastic sheets on too long after seeds sprout
Applying fresh grass clippings before they fully dry
Failing to secure cover edges with staples, stakes or stones
Not removing landscape fabric once grass reaches 2-3 inches tall

Proper preparation, application, anchoring, timing, depth and material selection ensure your seed cover performs its protective magic on the path to mature grass!

Mistakes to Avoid When Covering Grass Seed

Seed covers protect your grass seed investment, but only if applied correctly. It’s easy to make missteps that deprive seeds of the ideal germinating environment. Be aware of these common grass seed covering mistakes:

Using Too Thick of a Cover Layer

It’s important not to overdo it when applying seed covers:

Excessive layers block sunlight from fueling growth and turn covers into growth barriers.
More than 1⁄2 inch depth of materials like straw or peat moss can prevent shoots from emerging.
New grass struggles to push through dense, thickly matted covers.
Overly thick blankets also absorb too much moisture intended for seeds to absorb.
Follow package instructions for application depth, usually 1⁄4 inch or less.

Too much of a good thing backfires when heavy covers work against seedlings instead of protecting them.

Letting Uncovered Seed Dry Out Before Covering

Ideally, seeds should be covered immediately after planting:

Even a few hours of direct sun or wind exposure can dry out seeds, killing their germination potential.
Bare exposed seeds are also at risk of washing away or becoming bird food.
If an interruption occurs between seeding and covering, lightly mist seeds to keep them moist.
Skip seeding if rain or unreliable cover installation is imminent.
It’s better to wait a day for favorable conditions than to sow seeds you can’t cover promptly.

Unprotected seeds are extremely vulnerable – losing viability in as little as several hours without cover.

Allowing Covering Material to Blow or Wash Away

Unsecured covers are prone to displacement:

Lightweight materials like straw, peat moss and compost easily shift if edges aren’t anchored down.
Wind catches loose edges, lifting entire sheets of cover material away in gusts.
Heavy rain can carry unsecured covers into drainage areas, leaving seeds exposed.
On slopes, erosion quickly carries away loosely applied materials.
Weigh down edges with stones, stakes, or landscape staples every 1-2 feet.

Take time to properly fasten covers down so your efforts don’t literally blow away.

Forgetting to Water-In Covers

Dry covers repel water and don’t adhere well:

A light misting after positioning natural materials helps particles interlock and bond with the soil below.
Dry loose particles tend to shift together rather than sticking in place.
Watering after covering also pre-moistens seeds so they immediately imbibe water and kickstart germination when ready.

Don’t spread covers onto dry dusty soil and expect them to remain in place and effective.

Using Low-Quality Cover Materials

Not all covers are created equal:

Avoid seed-filled hay, inferior grade straw, unfinished compost and diseased grass clippings.
Unscreened compost and manure may contain viable weed seeds leading to lawn invaders.
Hay harbors significantly more weed seeds than straw that can take root in your lawn.
Herbicide-treated grass clippings damage establishing seedlings.
Inspect covers and ensure suitability as seed protection vs just a discarded waste product.

Saving a few bucks on covers contaminated with seeds, chemicals or disease causes problems.

Neglecting Regular Sprinkling

Erratic watering under covers leads to failure:

Seeds dry out quickly with insufficient moisture – protective layers are not a substitute for regular watering.
Natural materials must be re-moistened after drying or they repel additional water.
Lack of moisture, especially in the first 5-7 days, results in poor germination even if seeds don’t wash or blow away.
Ensure appropriate irrigation under covers for seeds to absorb water and successfully sprout.

No amount of protection can save seeds that simply dry out from lack of sufficient moisture.

Leaving Landscape Fabric Down Too Long

Fabric covers require careful removal:

Extended placement obstructs light reception, gaseous exchange, and upward growth after germination.
Grass becomes thin and elongated as shoots reach for sunlight through the fabric.
Plants quickly grow too large to pass through the holes. Removing fabric uproots the grass.
Monitor growth and remove fabric as soon as the second mowing would normally occur.

Fabrics are great for establishment but cause major issues if left down too long.

Getting every step right when sowing grass seed and protecting them with covers takes patience and care. But it’s worth the effort for optimal germination, lush growth, and the lawn of your dreams!

Overseeding Existing Lawns

When overseeding thin or damaged areas of an established lawn, seed covers play an important role in blending new grass. Follow these tips to integrate additional grass plants with your existing turf:

Use a Leaf Rake to Loosen the Top Layer

Before overseeding, use a leaf rake to gently disturb the soil’s surface:

Lightly drag the rake across areas to receive new seed to scratch the ground.
This helps existing grass recover from matting and improves seed-to-soil contact.
Take care not to aggressively tear and rake up the lawn. The goal is just to prepare the upper surface.
Excessive soil disruption brings up weed seeds that compete with the desired grass seed.

Gentle leaf raking prepares existing turf for integration with new seedlings.

Apply Grass Seed Before Cover Material

Position seed in contact with soil before adding protective covers:

Broadcast overseeding mix thinly and evenly across thin or bare spots in need of infill.
Once seeds have settled into light contact with soil, add preferred cover material.
Cover slowly and systematically to prevent moving seeds away from optimal soil contact.
Mist the area after seeding to temporarily adhere seeds if an interruption occurs before covering.

Proper seed-to-soil positioning must be maintained for successful overseeding.

Use Thinner Layers of Covers

When overseeding into existing grass, covers require careful depth control:

Apply very thin 1⁄4 inch or less layers of straw, peat moss or other overseeding cover.
Just a dusting provides ideal protection without smothering the surrounding mature grass.
Take care when spreading not to bury or wash seeds down into turf crowns too deeply.
Heavier layers are likely to damage existing grass you’re trying to maintain and supplement.

Overseeding covers must protect seedlings without harming surrounding turf.

Consider Cover Alternatives

Some cover options integrate better than others:

Chopped leaves or grass clippings blend in well with established lawns as they decompose.
Light compost topdressings add organic matter while protecting new seeds.
Landscape fabric is difficult to install on existing grass without damage or matting.
Loose fluffy covers are less disruptive than rolled erosion blankets.

Select overseeding covers compatible with maintaining healthy surrounding turf.

Mist Covers to Avoid Displacement

Use gentle misting to adhere covers on existing grass:

Light misting sets covers in place without washing away new seeds or tearing up turf.
Allow covers to dry before additional watering to avoid shifting seeds with excess moving water.
Consider skipping watering in if rainfall is expected shortly.

Take care when watering-in overseeding covers to avoid damaging the lawn.

Monitor Moisture Levels

Overseeded areas need more frequent sprinkling:

New grass seeds and seedlings demand consistent moisture near the surface.
Surrounding thicker, established turf tends to absorb more water leaving less for new seeds.
Light daily sprinkling prevents new seeds from drying out under protective covers.
Allow soil 2-3 inches down to partially dry between watering to encourage roots to stretch deeper.

Manage irrigation carefully when overseeding to sufficiently water new seedlings without overwatering mature surrounding grass.

Time Cover Removal Carefully

Account for disparate growth between existing turf and newly seeded grass:

Avoid leaving fabric down once new seedlings are 2-3 inches tall, even if surrounding grass seems shorter.
Remove covers gradually as seedlings establish to prevent damage from exposure or mowing.
Let biodegradable covers deteriorate and thin over time along with existing grass growth.

Staggered germination and growth rates make overseeding cover removal timing a balancing act.

When overseeding into existing turf, seed covers require precision placement and a gentle touch to generate lush, blended grass plants. But the rewards are a thicker, healthier lawn.

When to Remove Grass Seed Covers

Seed covers provide temporary protection and ideal germinating conditions. But at some point removing covers is necessary for further grass growth. Follow these tips for timing removal:

Remove Fabric Covers Once Seedlings Reach 2-3 Inches

Landscape fabric and woven ground covers:

Should be taken off once the new grass plants have grown to 2-3 inches tall.
Extended placement obstructs light and air exchange that young grass seedlings need.
New shoots quickly grow too large to keep pushing through fabric holes as intended.
Delaying removal leads to yellowed, elongated, matted growth as seedlings stretch for sunlight.

Fabric removal triggers the shift from seed establishment to active turf growing mode.

Look for Second Mowing as Biodegradable Cover Removal Guide

Covers made of natural materials like straw, peat moss and compost:

Can be left in place longer since they slowly break down over time.
Should be mostly diminished by the time the new grass needs its second mowing.
Layers will have thinned enough within 3-5 weeks for grass blades to grow through and be cut.
Supplement initial covers with 1⁄4 inch maintenance layers as the original materials decompose.

Plan biodegradable cover removal for when quick juvenile growth transitions to regular mowing.

Monitor Moisture After Removing Covers

Once covers come off, moisture management changes:

Removal exposes new grass plants to sun, wind, and dryness for the first time.
While covered, grass largely relied on subsoil moisture wicking up. Now foliage transpires moisture.
Remove covers in the morning before heat builds to avoid sudden wilting.
Begin regular top-watering regimen to sufficiently hydrate uncovered seedlings.

Take steps to prevent moisture stress when grass no longer has protective covers.

Examine Grass Growth Stage Rather than Date

There is no set date or timeframe when covers universally should come off:

Grass growth varies significantly based on weather, season, soil fertility, and other factors.
In peak spring, covers may only need to stay on 2 weeks before removal.
Cool fall weather may necessitate keeping covers on for a month or more.
Let the maturity of new grass plants dictate removal timing rather than the calendar.

Base removal on the condition of plants, not an arbitrary date.

Remove Sections of Cover as Growth Dictates

For large lawns or non-uniform growth:

Pull back covers section by section as new growth justifies removal in each area.
If grass establishes and grows faster in sunnier sections, uncover those areas first when ready.
Leave covers in place until shaded sections catch up to prevent exposing premature plants.
This allows tailored removal based on microclimate growth variations.

Localized cover removal provides flexibility for real-world lawn variability.

Let Sunlight Shine Through Before Full Removal

For new delicate grass stands:

Gradually expose seedlings to direct sunlight to adapt them to uncovered life.
Partially peel back covers or thin layers out incrementally over 2-3 days.
Transitional exposure hardens off tender grass before full cover removal.
Monitor for wilting, curling or other signals of light or heat stress during the transition.

Starting with partial unveiling gives tender shoots time to adjust.

Getting timing right for removing grass seed covers takes patience and attention. But once your new grass is firmly established, that beautiful lush lawn will thrive!

Caring for Newly Germinated Grass Seedlings

Seed covers provide temporary protection through the initial germination phase. Once covers come off, grass plants are on their own and need careful ongoing care. Here are key tips for nurturing newly uncovered seedlings:

Begin Regular Watering After Cover Removal

Moisture management changes without protective covers:

Uncovered seedlings lose moisture faster through foliage transpiration and direct soil evaporation.
Shallow new roots have limited ability to tap water from deeper soil layers.
Avoid moisture stress by switching to frequent light top-watering as covers come off.
Prioritize watering in hotter or windier microclimates that dry out fastest.
Look for leaf curling or wilting as signals to increase watering frequency.

Preventing moisture loss is imperative for newly exposed grass stands.

Apply a Starter Fertilizer

Young grass has limited nutrient reserves to support growth:

Incorporate starter fertilizer when preparing seedbeds according to package rates.
If not done during planting, apply a specially formulated starter fertilizer once covers are removed per product instructions.
Look for phosphorus to promote rooting and nitrogen for healthy green shoots.
Light doses of nitrogen every 4-6 weeks prevent seedling yellowing while minimizing growth surges.

Starter fertilizer feeds establishing seedlings during their vulnerable early weeks.

Mow New Grass at Correct Height

Mowing too soon or too short damages tender new growth:

Make the first cuts when seedlings reach 3 inches tall using sharp, clean mower blades.
For the first month, mow no lower than 2 inches to avoid scalping fragile roots and shoots.
Allow the grass to dry fully before mowing to minimize tearing of moist leaves.
Remove only 1/3 of blade height per mowing until the lawn matures.
Collect clippings to prevent smothering new growth until plants thicken up.

Careful first mowings help new grass transition to a maintenance cutting regime.

Monitor Growing Conditions

Pay close attention to the environment for new grass:

Watch for signs of disease like curly leaf tips, lesions, or fungal growth indicating issues.
Treat any disease outbreaks immediately to prevent devastation of delicate new stands.
Ensure proper soil pH, drainage and nutrients through testing if grass struggles to thrive.
Adjust care protocols as needed based on performance – more fertilizer, fungicides or pH amendments.

Proactively manage conditions to optimize success establishing a healthy lawn.

Overseed Bare Patches

It’s common to have thin or bare areas even after planting:

Reseed small bare patches a second time to infill and achieve full coverage.
When overseeding, use very light cover layers to avoid harming tender adjacent growth.
Ensure good seed-to-soil contact and sufficient starter fertilizer for germination.

Repeat patching fills in gaps as part of the lawn maturation process.

Prioritize Weed Prevention

Weed invaders aggressively exploit developing lawns:

Scout constantly for emerging weed seedlings like crabgrass and dandelions.
Pull by hand or spot treat with selective herbicide before weeds grow extensive roots.
Set mower blades higher to reduce stress on grass while preventing weed flowering.

Eliminate competition early so grass can win the turf battle and develop properly.

Let New Roots Grow Deep

Resist the urge to overwater as grass matures:

Allow the top inch of soil to partially dry out between watering to encourage roots to stretch deeper.
Light daily watering leads to shallow roots dependent on constant irrigation.
Deep weekly soakings build healthier grass that’s more drought tolerant.
Reduce watering frequency as seedlings transition to an established lawn.

Sparingly watering new grass properly develops extensive roots over time.

With diligent care from seed to seedling, your new grass will quickly establish into a thriving lawn!

Key Takeaways on Grass Seed Covers

Choosing the right protective cover for newly planted grass seed can make all the difference between success and failure for your lawn. Here are the key takeaways:

Cover grass seed immediately after planting to retain moisture, moderate soil temperature, deter pests, and anchor seeds in place. Leaving seeds uncovered risks washout, desiccation, consumption, and failed germination.
Select a cover material that is lightweight, breathable, and won’t compact into a dense mat. Popular options include clean straw, peat moss, compost, shredded leaves, or landscape fabric. Avoid covers with weed seeds that could germinate.
Spread cover evenly in a thin 1⁄4-1⁄2 inch layer so as not to bury seeds too deeply or obstruct sunlight and air. Mist after application to adhere cover particles to seeded soil. Weigh down edges to prevent displacement.
Monitor moisture under covers and irrigate lightly daily. Seeds still need consistent watering to germinate even when protected. Let top layers dry between watering once sprouts emerge.
Remove covers at the right time – when seedlings are 2-3 inches for fabric or ready for the second mowing with biodegradable mulch. Gradual removal hardens tender shoots.
Proper seed cover installation, maintenance and removal leads to successful grass germination and growth. Taking steps to safeguard seeds pays off with a thriving new lawn!

Frequently Asked Questions about Grass Seed Covers

Q: How much cover material do I need?

A: Aim for 1-2 bales of straw, 1-2 cubic feet of peat moss, or 2-3 cubic feet of compost per 1000 sq ft of lawn. Covers should be just 1⁄4-1⁄2 inch deep.

Q: Should I water newly planted grass seed before or after covering?

A: Water seeds thoroughly before covering to provide sufficient moisture from below. Then mist after covering to adhere particles. Continue regular light watering for the first 2 weeks.

Q: Can I use hay instead of straw as a seed cover?

A: Avoid hay, which contains more weed seeds. Opt for clean oat, wheat or barley straw. Shake out bales to remove debris before spreading.

Q: How do I know when to remove grass seed covers?

A: Remove fabric covers at 2-3 inches growth. Let biodegradable mulch covers naturally deteriorate until the second mowing. Monitor seedling height vs blindly following a date.

Q: Can I reuse landscape fabric or straw bales as covers?

A: Yes, fabric and straw can be reused for years if cleaned and stored properly out of sunlight. Discard plastic sheeting after one use.

Q: Should I cover grass seed if rain is expected?

A: Yes, otherwise heavy rain can displace seeds. Use a breathable cover like straw. Avoid plastic sheeting that won’t allow penetration of rainwater to seeds.

Q: Can too much cover material prevent grass seed from germinating?

A: Yes, excessively thick layers block sunlight and air, compact the soil, and get waterlogged. Stick to 1⁄4-1⁄2 inches of cover material at most.

Q: How do I keep seed covers from blowing away?

A: Anchor the edges with rocks, staples, or stakes. Fabric covers and plastic sheeting especially need edges secured to prevent wind lifting.
