I found a nice grow spot for next year lots of sun and privacy but the soil is clay and hard packed, I got some Miracle Grow in powder form and I think I might be able to fix the nutrition problem by tilling the powder in to the soil. The drainage is crap so what could I use to improve it? Also it is 40 or so yards away from a creek or something it doesn't get scummy really and runs year round but I'm not too sure if it is safe to use on my plants.
