How to Overseed Your Lawn Without Wasting Your Time Aerating

Not all grass seeds are the same. Depending on where you live and what grass has already taken root on your lawn, you’ll want to pick the right seed to take root.

When purchasing your seed, it’s better to over-buy than under-buy. You won’t run into issues over spreading seeds during the overseeding process, but putting too little down could result in a patchy lawn.

Generally, you can overseed a lawn any time of the year, but you might want to pick a several-week period where you can avoid foot traffic on the newly seeded sections.

For some, depending on the size of the yard, this might mean overseeding in sections instead of doing the lawn all at once.

When you overseed without aerating your lawn, you’ll want your grass as short as possible to start. That means mowing it so it stands between 1 1/2 to 2 inches tall.

The low grass will give the seed the best chance of reaching the soil and taking root. Keeping the grass low also means it’ll be several weeks before you need to mow it again, cutting down on foot traffic.

While you don’t need to aerate the lawn, you’ll need to rake or dethatch the freshly mowed grass. If you’re using a manual rake or dethatcher, just drag it along the lawn the same way you’d rake leaves. In the case of a motorized dethatcher, push the rake across the yard in a criss-cross pattern. 

Dethatching your lawn will remove any dead grass, making it easy for new seed to take root.

Use your hands, a push spreader, or a hand spreader to distribute grass seed across your lawn, paying close attention to areas with bald patches or thinning grass. Spread half the seeds in one direction and the other half perpendicular to the previous direction to create a pattern. This can encourage fuller coverage.

Use a garden rake to comb over the areas you spread seeds in. This can help the seeds reach the soil and prevent them from being eaten by a bird or swept away during watering. Rake in all directions to avoid dragging seeds toward a single spot.

Using manufacturer’s guidelines, use a spreader to fertilize the overseeded portions of your lawn. You should use about 2 pounds of fertilizer for every 1,000 square feet of overseeded lawn. 

Depending on the type of grass you have and your preferences, you can choose between an organic or synthetic fertilizer.

Now, it’s time to water and wait for your seeds to take root. 

Aim to water your lawn two to three times a day. Water the overseeded areas in spurts, taking care not to overwater them. They’ll benefit from small watering sessions several times a day. This is when an irrigation system or a garden hose can come in handy.

During this time, avoid walking on the lawn whenever possible. Keep children and pets off the grass, and step gently on the area only if necessary. 

You’ll likely need to stick to this watering routine for several weeks (up to four) until you see signs of the grass seed germinating.
