I raise african violets and find a mixture of 1/3 Miracle-Gro AV Potting Mix and 2/3 vermiculite makes a perfect growing medium for leaf cuttings and also to pot up the resulting baby plants. I feed every time I water with Miracle-Gro Liquid AV Food at 8 drops to a quart of filtered water. My plants bloom almost constantly with only short rest periods in between.
