Here are some of the most frequently asked questions about how to grow healthy African violets, along with prize-winning violet grower Jessie Crisafulli’s best advice. Her methods have produced a houseful of continuously blooming African violets, many of which sport blue ribbons won at flower shows.

African Violet Care | Frequently Asked Questions

What window exposure is best? African violets should grow well in any window with good bright light, not shaded by a porch or trees. In south-facing windows, protect violets from hot sun in summer with sheer curtains or blinds. African violets do well in a south window in the winter. For east and west windows, check to see that plants do not get too warm when the sun is in that area. North windows will provide sufficient light to bloom most of the year. Keep plants close to the window for maximum light. An African violet on a table in the middle of a room may look pretty, but may not receive sufficient light to keep blooming.

What about fluorescent light? If you do not have bright window light, then fluorescent fixtures are the answer. I use four-foot fixtures with two cool white bulbs in each. I have used one warm white and one cool white bulb in a fixture with good results. Special plant bulbs, called “grow lights,” also produce an attractive plant. The optimum distance from pot to light is 8 to 12 inches.

How often should I water my African violet? The best guide is to feel the top of the soil: if it is dry to the touch, then it is time to water. African violets should be allowed to dry out between each watering for best results. Overwatering can kill a plant. The fine roots of an African violet need air, which cannot penetrate a soggy wet soil mass.

Should I water from the top or bottom? Either is fine. It is important not to use cold water; lukewarm or warm is preferred. If you water from the top, be careful not to get water on the leaves when the plant is in the sun; this is to avoid leaf spots. If you water from the bottom, the excess water should be discarded after the plant has taken up all it needs. Do not allow an African violet to sit in water indefinitely.

What size pot is best? Overpotting will delay bloom. The usual recommendation is that the pot diameter should be one-third the spread of the leaf span. For example. if the plant’s leaves measure 9 inches from one leaf tip to the opposite leaf tip, use a 3-inch pot. Violets bloom best when they are potbound.

Which is better, a clay or plastic pot? Either is suitable. Plastic pots can be kept cleaner and will hold moisture longer, and are what I use for violets. Clay pots allow the air to penetrate to the roots, which is beneficial. but they dry out faster. I use clay for succulents and cacti. Salts may build up on clay pots. rotting violet leaves resting on the top rim. Protect the leaf stems by using a folded strip of aluminum foil to cover the top rim of a clay pot.

What brand of fertilizer should I use? Any reputable fertilizer is good. I like to use a water-soluble fertilizer. A balanced fertilizer with equal parts of nitrogen (first number), phosphorus (second number), and potash (last number), such as 18-18-18, has produced good show plants for me. If you are not getting good bloom try a fertilizer with a higher middle number, which will contain more phosphorus, such as 15-30-15
