How do I prepare for overseeding?

Mow Low. Before overseeding your thin lawn, cut your grass shorter than normal and bag the clippings.

After you lay down your seedlings, they'll need time and the right environmental protection to grow. They'll need to acclimate and set roots before the first mow, so during the first two to four weeks post aerating and overseeding, don't mow.

Can you fertilize and seed at the same time?

When seeding a lawn, you should never apply the fertilizer and seed together. This can cause an uneven distribution of the materials resulting in patchy areas or seedlings burned by excess fertilizer. It is best to spread the fertilizer just prior to planting the seed.

Is it good to overseed before rain?

Best practice is to avoid overseeding a soggy lawn. Instead, wait for the lawn to dry, and check to make sure there's no rain in the immediate forecast when you plan to seed. Then, properly prepare your lawn for overseeding so the seed can establish itself before any upcoming rainstorms.
