1. Will Japanese Stiltgrass crowd out other grass during overseeding season? 2. When is the best time to start overseeing? 3. When adding to soil for overseeding, should I use manure or leaf growth?

Japanese stilt grass is a summer annual that will die with the first frost,similar to crabgrass. Now is the ideal time for overseeding,till about October 15th.Manure has too many weed seeds, avoid using it as a top-dressing.The leaf gro is a cleaner product. To control Japanese stilt grass, apply a pre-emergent crabgrass preventer like barricade (prodiamine) in March.https://www.extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG102%20Lawn%20...
