Most of the area at our cabin is prety wooded, but there is a 30 yard by 30 yard area that was already cleared by the previous. There is a lot of fern and some sort of thorny weed that is growing in that area now. We had planned on tilling the area to basically pull all of the weeds out, lime, and then plant clover. Is there anything else we should do? Also, there is the Imperial Clover at the hunting store for about $34 for a 4 pound bag. Is this really that superior to clover that you could buy at Agway? Also, how high does the clover grow and is there any cutting or other maintenance required?
