Question: Within the realm of indoor plants, African violets hold a special place due to their captivating beauty. These delightful plants thrive in indirect light, but lately, I’ve encountered a puzzling issue. The once lush leaves are now curling, and growth seems to have stagnated. Despite meticulous watering, I’m at a loss. How can I restore their vitality? – Bianca

Answer: Dear Bianca, besides the basic care that we routinely provide for African violets, of the Saintpaulia ionantha species, there are a few intensive care steps that need to be taken at least once a year. These steps include repotting, changing the substrate, and fertilizing.

These steps are simple yet essential to restore vitality to tired plants. Most likely, the substrate has depleted of nutrients, and the root system needs new roots to adequately nourish the plant. Purchase substrate specifically designed for African violets or plant them directly in potting soil. Make sure to bury the stem that formed from the fallen old leaves. New roots will emerge from this stem, enhancing the plant’s nutrient absorption. Avoid performing this transplant during the cold winter, as manipulating the plant during its dormant period can lead to rot.

Keep an eye on the plant after transplanting until the first leaves emerge. Now, you can fertilize without hesitation. Try to get fertilizers formulated for violets and always follow the manufacturer’s recommendations regarding dosage.

Understanding African Violet Requirements

Lighting: African violets are adapted to thrive in environments with filtered or indirect light. Placing them near east or west-facing windows is ideal, as they receive sufficient light without being exposed to harsh direct sunlight. In regions with limited natural light, supplementing with fluorescent grow lights can be beneficial.

Temperature and Humidity: African violets flourish in stable indoor temperatures ranging from 65 to 75°F (18 to 24°C). Maintaining a humidity level of around 40 to 50% is essential, especially during drier months. To increase humidity, consider using a humidity tray or a room humidifier.

Watering: Achieving the right balance in watering is vital. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt. Water African violets from the bottom by placing the pot in a saucer of water, allowing the plant to absorb moisture through the drainage holes. Always use room-temperature water to prevent shock to the plant’s sensitive roots.

Soil and Potting: Select a well-draining potting mix specifically formulated for African violets. Alternatively, create a mix by combining peat moss, perlite, and vermiculite in equal parts. Repot your African violets annually or whenever you notice they’ve outgrown their current container. Gently remove the plant from its pot, carefully detangle the roots, and place it in a slightly larger pot, ensuring the crown remains at soil level.

Fertilization: African violets have specific nutritional requirements that can be met with a balanced, water-soluble fertilizer formulated for these plants. During the growing season, which typically spans from spring to early fall, feed your African violets every 2 to 4 weeks. Dilute the fertilizer to half the recommended strength to avoid overfeeding.

Pruning and Deadheading: Regularly remove spent blooms and damaged leaves to encourage continuous flowering and maintain the plant’s overall appearance. To promote bushiness, pinch back the tips of the plant’s stems. This will encourage the development of new growth from the base of the plant.

Leaf Curling and Stunted Growth: If you notice the leaves of your African violets curling and growth stalling, it’s time for some rejuvenating measures. Periodically, usually once a year, engage in intensive care practices such as repotting and substrate replacement. This process revitalizes the plant by replenishing nutrients and promoting healthy root growth.

Repotting for Revitalization: To initiate the repotting process, carefully remove the African violet from its pot and gently shake off the excess soil. Trim any dead or damaged roots and repot the plant in fresh, well-draining African violet potting mix. Ensure that the crown of the plant is level with the soil surface. Post-repotting, maintain a vigilant eye for the emergence of new leaves before resuming regular fertilization.
