For years I've been using Fafard's Complete Planting Mix, in the purple bag, which is basically just a plain organic soil. To it I add various amendments, including bone meal, blood meal, kelp meal, epsom salts, egg shell, dolomite, also worm castings and/or mushroom compost when I can get it. However this year I can't find the Fafard's around here, so I got a few bags of Dr. Earth's All-Purpose Potting Soil: Looks like it already has some amendments added to it. The ingredients they list are: Forest Humus, Fir Bark, Peat Moss, Pumice, Earthworm Casting, Kelp Meal, Alfalfa Meal, Soybean Meal, MicroActive™ Seaweed Extract, Aloe Vera, Yucca Extract, Oyster Shell & Dolomite Limes. We have also included ProBiotic® beneficial soil Microbes plus both Ecto and Endo Mycorrhizae. I also got a bag of Dr. Earth's All-Purpose Compost, which coincidentally lists the exact same ingredients. I thought I'd use that in place of mushroom compost. Any suggestions on how or if I should adapt my soil recipe with Dr. Earth's versus Fafard's? Should I cut down or eliminate my usual additives? I'm afraid this new soil could be pretty potent, and I don't want to shock the young ones on their first transplant.
