I did find some ProMix Premium over the weekend with "growth enhancer" stuff and bought a bale out of desperation since garden centers here aren't stocked yet. My first question over their choice of words - is it just a growth enhancer or does it actually contain mycorrhizae? Second question - the bale I purchased was obviously left over from last year since it was outdoors, covered with snow and frozen solid - would mycorrhizae survive those conditions?
Gosh, Caroline - you raised an interesting question. Here I was, thinking I could inoculate potting soil with some compost and maybe a bit of garden soil but my soil here in the midwest might not contain the mycorrhizae needed by a potted lemon or banana tree. I may be pulling out my hair trying to accommodate my various potted plants.
