If you have bare patches in your lawn, it’s a simple project to reseed them. It just takes some simple prep work and two to three weeks of everyday dedication. That’s the daily watering part. And if you’re unwilling to make that commitment, don’t even bother. You’re just wasting your time.
The best times for reseeding patches are mid-spring and mid-fall. Yes, you can do it in the heat of summer, but it’s tough. The heat makes it next to impossible to nurse along the seedlings until they can get by without your help.
Start by pulling out and scraping up any dead growth to expose only soil. Then rake the soil to loosen it to a depth of an inch or so. Sprinkle seed over the area, but do it carefully. Too much or too little seed is a mistake. Seed just a small area over the soil and then picture a square inch of the spot. It might sound crazy, but count the seed in that inch. Your goal is to get about 15 or so seeds per square inch. Once you know what that looks like, try to seed the rest of the patch with the same concentration of seed. Next, sprinkle topsoil over the seeds. DON’T put it on too thick or the seeds won’t be able to sprout through the soil before they “run out of gas” and die. Aim for about ¼ in. of coverage. The soil isn’t so much for growing as it is to keep the seed from drying out.
Now comes the commitment part. Lightly sprinkle the area so the water penetrates about ½ in. Don’t soak it—just wet it. Every single day for the next two weeks, water it at least once a day; if it’s dry and windy, twice a day. Stick with it, and in a few weeks, the patch will blend right in.
