hi tlisk....very good advice from the previous posters. i'll tell you what works for me and i live in northern michigan. looks like you got the right idea in selecting an early finishing strain. i get cow manure from a local farmer and dig my holes, then mix manure with the existing dirt from digging the hole. not fresh manure, mind you.....some dry stuff. i know some people may cringe at this method, but it has worked very well for me. good luck on your grow littleguitar
