so i have eleven 5 inch plants which im planting this saturday.what i plan on doin is digging a bunch of holes(because the soil turns to clay after about 2 1/2 ft. down)and filling it with top soil,perlite,peat moss,and some builders sand.i might add some mushroom compost if i can find a lowe's around here. but its about 20 feet from a river and at the end of a farmers field(they know). either that method or a couple in some 5 gallon buckets. any suggestions??
