Aerated and overseeded our athletic field. Signs of chickweed and dandilions already... but at the same time, it's only been a month or so since I overseeded and the seeds have finally started sprouting. The new grass blades aren't really that established, so I don't want to destroy the work by putting down Momentum too early and killing the new seedlings. Is there a set time to wait to apply post emergent after seeding? FYI... Lesco's starter fertilizer was applied in late March to the entire field... about 54,000 square feet.
