How do I overseed a thin area in my lawn?


1. Assess the Area

Prior to overseeding, look closely to ensure there are no underlying issues causing the thinning, such as grubs, or lawn fungus. If so, it’s best to treat these problems first before applying new seed. If there are no signs of insects or disease, proceed to step 2.


2. Mow the Area on the Lowest Setting

Prior to mowing, adjust your mower height to its lowest setting, and be sure to bag clippings afterward. Low mowing ensures the seed makes it to the soil instead of sitting on top of any existing grass.


3. Rake the Area

After mowing, vigorously rake the area with a metal rake or break up the soil with a garden weasel to ensure that your seedlings are able to establish good seed-to-soil contact to aid in germination and growth.


4. Spread Seed

Spread grass seed in the thinned area. If you are dealing with a larger area, use a spreader to ensure each space gets an equal amount of seed. If the bare spot is only a few square feet it is fine to apply the seed by hand. A good rule of thumb is to plant enough seed to cover the area with one even layer. There should not be multiple layers of seed.


5. Watering

Establish a consistent watering schedule to keep your seeds moist. New seedlings need to be kept moist to ensure they germinate properly. Water the seedbed twice a day for approximately 10 minutes at a time. Once your grass has germinated and reached a height of at least three inches, reduce watering to two to three times per week. This step is key to ensure proper germination and growth.
