4 months, 1 week ago Acorns and grass seeding Q&A Can I over seed with all those acorns all over my lawn? I can not get them up. - Patty - Comments Jo Co Master Gardener 4 months, 1 week ago The question is if you can have excellent seed-soil contact with the acorns on the ground. If so, then the acorns won’t bother the grass seed. If not, raking the acorns up would be essential before seeding. Here is the very latest from Ward Upham at KSU on dormant seeding: “The best time to seed cool-season grasses such as tall fescue and Kentucky bluegrass is September because the turf has more time to mature before spring crabgrass germination and the heat stress of summer. Dormant seeding of turfgrass is sometimes used to help fill in bare spots of lawns that weren’t overseeded in the fall. Dormant overseeding is done during the winter )December – February( when it is much too cold for germination. As with any seeding program, good seed-soil contact is vital. Several methods can be used. One method is to seed when there has been a light snowfall of up to an inch. This is shallow enough that bare spots can still be seen. Spread seed by hand on areas that need thickening up. As the snow melts, it brings the seed into good contact with the soil where it will germinate in the spring. Another method is dependent on the surface of the soil being moist followed by some freezing weather. As moist soil freezes and thaws, small pockets are formed on the wet, bare soil that is perfect for catching and holding seed. As the soil dries, the pockets collapse and cover the seed. A third method involves core aerating, verticutting or hand raking and broadcasting seed immediately after. Of course, the soil must be dry enough and unfrozen for this to be practical. With any of the above methods, seed germinates in the spring as early as possible.” Good luck with your dormant seeding.
