Am I too late to top coat my clover plot? I planted a clover plot last fall, it came up spotty at best but I understand that is common for year 1. I want to top coat this spring to help it along but I think I have missed the window for frost seeding. Mid 50 daytime highs and around 35 nighttime lows I am sure there is no harm in topseeding right now as the seeds are small enough where a light rain will drive them in. Anyone have additional thoughts on this, will this be a waste of time?
