When Baron Walter von Saint Paul first brought a flowering plant he called the Usambara violet from East Africa to Germany in 1894, little did he know how many people would fall passionately in love with the African violet. 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

    Are selfwatering pots good to use

      African violets can thrive in self-watering pots, but you will need to watch them to make sure they don’t get to wet and rot.

    I have four violets that I transplanted into clay pots and used African violet soil. I keep them under florescent lights and lost my flowers. The soil is dry to the touch and I only water when it is, but I have tiny mushrooms growing now. The plants look great but I am worried about the mushrooms. I also have little flies on them. Never had them before. Please help!

    My violets have developed a mildew on the blooms.
    what do I do to control that?

    • Brenda Darroch May 28, 2014 at 3:39 pm #

      Hi Theresa,
      It sounds like your African violoets may have been given too much water. Allow the soil to dry out completely before watering.

    My African violets blooms are drooping and becoming weak..should I let them fall off or trim off. And do I trim just the blossom or down to the stem

    • Brenda Darroch June 2, 2014 at 9:14 am #

      Hi Kristin,
      Once the blooms start to die, it is best to pinch the stem off. Be careful not to disturb and new buds that are making their way up.

    I have had my plant for a year. It is not blooming but I have lots of new leaf growth. Why is it not blooming? It is in the kitchen window, south facing, some protection from porch awning, I water from the bottom when dry. How do I get it to bloom again?

    I just watched a movie on TV that showed a persons planting an African Violet in the ground on a grave. I assumed that this type violet is strictly a potted plant….am I correct?

    I’ve had various A.V. for years and not long ago I found one I thought was unique. The leaf edges were white and the flowers were white smallish with pale green edges. When I needed to grow another of these I took a leaf, rooted it and later had three plants from this leaf. One plant developed like the original, but the other two were different. One was a pale lavender larger petals and the second was smaller petals pale lavender with a hint of green around the flower petal edges. Does anyone know why?
