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 African violet care, 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.

What window exposure is best for African violets? 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 you water African violets? “How often to water African violets?” is perhaps the most pondered African violet dilemma. 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. Once you’ve mastered how to water African violets, half of your work is done.

Should I water African violets 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 for African violets? 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’s the best fertilizer for African violets? 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

Should you withhold fertilizer when the African violet is in bloom? In my opinion this is poor practice. African violets need food when producing blossoms, and since the plant ideally should bloom continuously. It would severely deprive the plant if fertilizer were withheld.

What soil mix should I use? I use a mixture of two parts sterilized soil, one part coarse perlite, and one part coarse vermiculite. Any purchased sterilized soil can be used. Perlite and vermiculite help keep the soil loose and porous.

The lower leaves turn soggy — should I take them off? It is a good practice to remove all African violet leaves that have started to decay. It is a natural process for older leaves to die off. They will be replaced by new growth in the center of the plant. Any bottom leaves turning yellow or spotted should be removed.

What is wrong when the soil is wet but the plant seems limp? This may be an indication that the plant has been overwatered, and possibly crown rot has set in. There is not too much that can be done. You may be able to take off a healthy leaf or two to start a new plant, but the old plant may not live if the center crown has started to rot.

How often should I repot my African violet? Repotting African violets is beneficial to the plant’s lasting health. Repot in fresh soil every year or two at most. Do not necessarily use a larger pot each time you repot.

What should be done with an African violet has developed a thick stem below the bottom leaves? This is usually called a neck. It can be taken care of by setting the plant deeper into the soil when you repot. Use the proper size pot, not one that is too large or too deep. If the “neck” is too high, carefully remove some of the old soil from around the violet’s roots, so it can be lowered further down into the pot. If the soil and roots are hard and compacted, and cannot be loosened, then a portion of the bottom of the root mass can be sliced off with a knife. Repot so that the lower layer of healthy green leaves rests on the soil line at the top of the pot.

  • my violet has brown spots on the upper side of the plant and some of the leaves are turning yellow. What am I doing wrong.

  • 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?

  • 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 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?

    My VIOLETS DO very well in a room with a skylight until it gets hot where I live 100% or more I use air condoning but the leaves really droop I don’t have another place to put them house is mostly shaded help if u can?

  • Dimitris

    My violets are growing so beautifully on my windows sill. I think it helps to talk to them a bit :)

    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.

  • Kristin

    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

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

  • Theresa

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

  • Helen

    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!

  • Brenda

    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.

    • These are all I use. Do not let them dry out. Normally every week adding water is sufficient.

  • After blooming and petals dry out. What it’s the best way to handle these? Let them be or trim?
