Thanks for the info everyone. I've got the clover and chicory, I'll pickup some oats and plant about the oats at 1/3 the recommended rate. You have led me to another question about using Post (or other grass treatment chemicals).
I have a 6 acre lot planted last year with Ladino clover that has a lot of grass in it. Mowing has not helped substantially. The clover is very well established but I fear it will be overrun if it goes another year. Is there a better time to apply a grass killer through our summer season?
