Potting Mix
Soil for growing African violets needs to be loose and well-draining (Soilless mix). Excellent plants may be grown in a mixture of equal parts sphagnum peat, vermiculite and perlite. If you wick-water, you need a much lighter mix with a minimum of 50% perlite. The soil mixture should also be slightly acidic (pH 6.0 to 6.5). A good potting soil for African violets actually contains no soil at all. Potting soil needs to be very light and porous. Which will enhance aeration and keep the soil moist, not soggy. The pH of a potting soil is important, because if it is too high or too low, African Violets can not properly absorb nutrients.
