soil / soil mix
What type of soil or soil mix do you successful ws'ers use?
The year that I did ws, I used a potting mix (I *think* Miracle Grow?? - that was 2 years ago - can't remember) and am wondering if that is why I had such little success?
(I'm in Alberta - zone 3a, if that makes any difference in which soil to use?)
