Here in the south, we work hard to maintain a soft, luscious lawn. March is a key time to aerate and supplement the lawn with grass seed.
The first step is to know what type of grass you already have in your yard. We have Kentucky Fescue 31 but if you are unsure, take a picture, and a small patch of sod from your yard, a quarter size to your local nursery to ask them what type of grass seed you will need.
The next step to this process is to aerate the yard. I use a plug aerator, like this one and attach it to the back of my riding lawn mower.
Now, I know that I need to aerate because I have clay soil, but if you have sandy soil, you may not need to aerate. Also, if you are going to aerate, doing it at this time of year allows you to expose the soil without hurting your lawn through high heat. Spring is also a wonderful time to aerate because the soil is damp and soft.
Next, I spread the grass seed with a spreader according to the setting on the back of the bag.
Next, I ride back and forth, spreading the grass seed as evenly as possible across the lawn. I do stop and fill in any holes in the yard with additional seed.
Over the next ten days, I will keep an eye on the yard. As long as it either rains or the grass has morning dew, the seed will germinate. However, if we have several dry days, I will need to wet down the seed but that is rarely necessary.
In the next three weeks, the seed will germinate and fill in the lawn, making it lush and full.
