I've gotten behind on my preparation for planting my Imperial Clover. Is is too late to plow and disk and plant yet this year? Or would it be to my advantage to plow and disk this fall and again in the spring and then plant the clover in spring? My concern is that if I try to rush the planting, the weeds may not be killed off enough and they could come up and choke out the clover. Oh yeah, I have about an acre of a 5 acre grass field that I want/can afford to plant. Any suggestions? Thanks.
