Knowing how to reseed a lawn is part of owning a house. Inevitably, at times you’ll have bar patches on your grass, and knowing how to reseed a lawn properly will help you keep the garden looking good. It’s not a complex procedure, and knowing how to reseed a lawn organically doesn’t even take special knowledge. The process is also known as overseeding.
Step 1 - Dead Areas
Part of knowing how to reseed a lawn is determining whether you need to reseed the entire lawn or just smaller areas. In most cases, reseeding smaller areas will be perfectly adequate. The only times when you’ll need to reseed the whole lawn is if it has been neglected for several years. At that point the whole lawn will need to be aerated and thatched thoroughly.
The first step in knowing how to reseed a lawn is preparing the lawn for the grass seed. You can in theory do this at most times of the year, but you should avoid the winter. If you’re putting in new seed do it early enough for the grass to become established before winter bits.
Start by using a rake on the area. This will remove the thatch, which is the dead grass, and also help to loosen the soil. Where the soil has been bare for a while, you’ll do well to use an aerator on it. This breaks up the soil more effectively, allowing nutrients and moisture to penetrate properly. This will help the grass seed to grown and give good coverage.
Step 3 - Compost
Your new grass seed will grow better in good soil. You can help this process by putting some compost into the soil. You don’t need to use much, just enough to work into the ground and feed the seed. New top soil will also have the same effect, but compost tends to be cheaper.
Step 4 - Seed
There are so many types of grass seed on the market that choosing the right one can become confusing. Rather than having several different types of grass growing in your yard you should go for the same type of grass that’s already growing there.
With small areas you can spread the seed by hand. For an entire lawn use a mechanical spreader, allowing 4 pounds of grass seed to 1,000 square feet. After spreading, rake the seed into the dirt. You can use straw on top to protect it from the birds or cover with a thin layer of mulch.
Step 5 - Growing
Don’t just leave the grass seed to germinate and hope for the best. You’ll need to water it regularly, which in this case means twice a day for the first few weeks. The new grass seed will take about two weeks to germinate. After this you can water less often. Don’t move until the grass is established, until it’s about 3 inches high. Keep the grass about 2 ½ inches tall, rather than more closely cropped.
