Q: I believe my current grass is centipede sod. Can I fill in bare spots with centipede seed?
A: Sure, overseeding is a fine way to thicken centipedegrass sod growing in full sun. The best time to scatter seed is mid-May, when the soil is warm. ‘Tifblair’ is a good variety to use. Your biggest chore is to keep the upper inch of soil moist but not soggy for two weeks. It will take that long for the centipede seed to sprout and begin to fill the bare spots. Put down a light application of lawn starter fertilizer after you apply the seed. Irrigation should start immediately.
