Key takeaways
- Rake seed lightly into the soil and firm it, so less sits on top for birds
- Fine netting raised on short canes is the most reliable cover
- Garden fleece works well in cool spring and autumn weather
- Shimmer tape and old CDs help, but birds soon get used to them
- Keep netting taut and check it daily so birds and hedgehogs can't get caught
- Leave covers on until the grass is a few centimetres tall, usually three to four weeks
The best way to protect grass seed from birds is to hide it and cover it. Rake the seed lightly into the soil, then put fine netting or garden fleece over the top until the grass is up. Sparrows, finches, pigeons and blackbirds all love a freshly sown patch, and an uncovered one can be stripped quickly.
This guide covers the covers that work, the extras that help and when to take everything off. For the whole job from soil prep to first mow, see how to grow grass from seed.
Why birds go for new grass seed
A new seedbed is an easy meal: lots of seed lying on bare, crumbly soil. Sparrows also like to dust-bathe in fine soil, which scatters what’s left.
Birds are most interested in the first week or two, while seed sits on or near the surface. Once seedlings are up and rooted, they lose interest in the patch.
Rake the seed in first
The simplest protection costs nothing. After scattering seed, rake it very lightly so most of it is just under the surface, no more than about 1cm deep. Then firm the soil by treading it or using the back of a rake.
A light rake hides most of the seed just under the surface, so birds have far less to find.
Seed that’s covered is harder for birds to find. It also stays moist and comes up faster, which shortens the time it needs protecting. Water gently with a fine spray so the seed isn’t washed into puddles.
Fine netting on short canes
Fine netting is the most reliable cover for new grass. It keeps birds off the seed while letting light, rain and air through.
- Push short canes into the soil around the edge and through the middle, about 50cm to 1m apart.
- Top each cane with a cane cap or an upturned pot so it can’t tear the net.
- Stretch fine mesh netting over the top so it sits a few centimetres above the soil.
- Pull it taut and peg or weigh down every edge so birds can’t get underneath.
Loose or baggy netting can trap birds and hedgehogs. Keep it tight, and check it every morning. If anything does get caught, carefully cut it free.
Netting held just above the soil and pegged at every edge stops birds reaching the seed.
Garden fleece for spring and autumn sowing
Horticultural fleece is a light white fabric that you lay straight over the seedbed. It keeps birds off and holds a little warmth in, which helps seed come up in cool spring and autumn weather.
Lay it flat over the sown area and weigh down every edge with bricks, pegs or planks. You can water straight through it. In warm, sunny spells take it off, or the seedlings can get too hot underneath.
Fleece over a new lawn keeps birds off and helps the seed along in cool weather. Weigh down every edge.
Shimmer tape, CDs and other scarers
Shimmer tape is a shiny strip that flashes and rustles in the breeze. Strung in a criss-cross pattern on canes just above the seedbed, it puts birds off for a while. Old CDs on string do a similar job.
Birds soon get used to anything that doesn’t change. Expect a week or two of benefit, and move things around every few days to keep them guessing. Fake owls and scarecrows work the same way and fade just as quickly.
Use scarers as an extra on top of netting or fleece, or for awkward shapes that are hard to cover.
Criss-crossed shimmer tape flashes in the breeze. Move it every few days or the birds will soon ignore it.
When to take the protection off
Leave covers on until the grass is a few centimetres tall and well rooted, usually after three to four weeks. By then birds aren’t interested and the seedlings can cope with a bit of traffic.
Once the new grass is a few centimetres tall and rooted, the covers can come off.
Lift netting and fleece gently, so you don’t pull up young grass. Keep watering in dry spells, and wait until the grass is about 7-8cm tall before its first light trim. The guide to watering a lawn covers how much new grass needs.
Best times to sow grass seed
Grass seed comes up best from late August to September, or in spring from April to May. Autumn is often easier: the soil is still warm, rain is more reliable and there’s less going on in the garden for birds.
Spring sowings coincide with nesting season, when birds are busy and hungry, so cover them well. Avoid sowing in midsummer heat unless you can water every day. The lawn care calendar shows where sowing fits into the year.
Common mistakes when protecting grass seed
- Leaving seed on the surface. Rake it in and firm it, or birds get an easy meal.
- Laying netting flat on the soil. Birds can feed through it. Lift it a few centimetres on canes.
- Loose netting. Slack mesh traps birds and hedgehogs. Keep it taut and check it daily.
- Not pegging the edges. Birds walk straight underneath any gap.
- Taking covers off too soon. Wait until the grass is a few centimetres tall.
- Relying on scarers alone. Shimmer tape and owls only buy a week or two.
If pigeons are a problem in the rest of the garden too, the guide to deterring pigeons has more ideas. Feeding birds well away from the new lawn can help as well, and the seasonal bird feeding guide explains what to put out. Patching bare spots rather than a whole lawn? The guide to fixing a patchy lawn covers it.

Frequently asked questions
What is the best way to stop birds eating grass seed?
Rake the seed in, then cover it with fine netting on short canes. Raking in hides most of the seed. Netting held just above the surface, pegged at every edge, keeps birds off until the grass is up.
Does shimmer tape keep birds off grass seed?
For a week or two, but birds soon get used to it. It works best as an extra alongside netting or fleece. Move the tape around every few days to keep birds guessing.
Can I put fleece over grass seed?
Yes, fleece works well, especially in spring and autumn. Lay it straight over the seed and weigh down every edge. Water goes through it. Take it off in warm sunny spells so the seedlings don’t overheat.
When can I remove bird protection from new grass?
When the grass is a few centimetres tall, usually after three to four weeks. By then birds are no longer interested in the seed. Lift covers gently so you don’t pull up seedlings.
Do scarecrows or fake owls stop birds eating grass seed?
Not for long. Birds quickly learn that a fake owl or scarecrow doesn’t move. Shift them every couple of days if you use them, and rely on netting or fleece for real protection.
Should I sow extra grass seed to allow for birds?
Sow at the rate on the pack and protect it instead. Extra seed just feeds more birds. Keep a little back to patch any thin areas a few weeks later.
