I was thinking about frost seeding over my existing clover plots come april/may year after year to ensure a thick stand of clover that will choke out the majority of weeds. Does anyone use this method as opposed to starting from scratch every 3-5 years? Also trying to avoid the ridiculous cost of "arrest and slay" herbicides.... Typically, mowing keeps my weeds totally suppressed so i would think this would think frost seeding every year would keep these clover/chicory stands pretty nice. Thoughts?
