Getting ready to buy the seed for planting a 4 acre plot. I' m going to plant Imperial Whitetail Clover and can' t decide how much to plant. They say 8 lbs./acre which would be 33 lbs. Would it be better to buy the 50 lb. bag and plant more than recommended or get the higher priced smaller bags. I think I read someplace that you can plant too heavy and not get as good results. Have done everything the soil test said so far and don' t want to mess up now. Thanks for any advice.
