How To Prep Your Lawn For Overseeding?

– Lower the blades on your mower as low as you can without consistently hitting dirt. While you are mowing it is important to bag and catch your clippings to help remove as much debris and clippings as possible.  -Repeat this process 2-3 three times in different directions.  

-Ensure good seed to soil contact by “roughing up” the ground using a rake or mechanical dethatcher. By doing this the ground will be more acceptable for seeds and you will also remove any dead material from your lawn.  – Next you should aerate you lawn. Aeration will also provide a good soil bed for seeds to germinate, similar to dethatching.

The amount of seed that you will use will depend on the type of seed you have picked.  Seeding rates are based on 1,000 square feet intervals so it is important to know the size of your lawn.
