I would love to hear how your planting turns out. For tillage I use a disc harrow. I did that on a 1/2 acre plot, then ran over it with a pulverizer to smooth it out, and planted clover. The clover came up well on about 3/4 of the plot--at least it looked that way-- but then I neglected it and the weeds took over. Obviously I don't know what to do to maintain the clover after it comes up and gets fairly well established--or maybe the problem was that it just looked pretty good but really wasn't well established.
