When receiving the plant, do not repot immediately but wait at least 6-12 months or until the spring. As African violets grow, the older leaves may be removed as newer ones form, leaving a bare stem closer to the soil. Remove your plant from their pot after adequately hydrating them. Remove as much root mass as the bare stem. Replant with fresh soil in the same pot but burying the bare stem, so the bottom leaves are near the soil line. Use an African violet potting mix with vermiculite and perlite, making up 1/3 to 1/2 of the mixture, so it is aerated to help with drainage. Using a terracotta or breathable pot with drainage holes will allow the air to circulate the root system and dry out more quickly. Ceramic pots are usable, too, with drainage holes. Water well and place a large, clear plastic bag over the planter to help create humidity. The roots will re-establish quicker. Check the moisture level each week to ensure they have adequate water. After six weeks, remove the bag and set them in bright to medium indirect light.
