Late Sept. this year, I planted a 1/4 acre of Imperial next to a 1/4 acre of Biologic Full Draw. I disced, limed, and fertilized each plot exactly the same. The Biolgic grew and is still growing like crazy. The Imperial barely came up at all. What did come up was very small leafed plants. The Biologic plants are huge and look like a patch of lettuce. This was my first experience with both products.
