The reasons spring overseeding can be the better option for returning your thin and damaged lawns to health compared to the appearance you would have from fall overseeding your bare patches.

It helps to aerate existing lawns before and after seeding. Spring overseeding helps stress caused by disease, insects, and drought.

Preparing your Lawn

First, you have a few things to do before sowing grass seed.

Dethatching lawns with a mechanical dethatcher or metal rakes can remove your thatch (a layer of organic material lying on the soil and stops grassroots from reaching the soil).

Mowing lawns then removing cuttings is vital because cutting to a length about 1 to 1 1/2 inches lets the sun and water reach your seeds.

Aerating is when the lawn region loosens compacted soil in an existing lawn and lets air and water penetrate, thus improving soil conditions.

Sowing

Grass seed is best spread with a seed spreader for even distribution. You should also apply double the amount of seed you would if starting your lawn from scratch.

Rather than overlap, you are better off spreading one pass in one direction, then the second pass in the sideways direction.

Once seeds are sown, you can add a little starter fertilizer. Also, make sure to minimize foot traffic. Make sure to water frequently, so the soil stays moist to encourage deep root growth.
