African Violets

Two questions.. I grow african violets; some produce great blooms for me while others refuse to do so.. How can I make them flower? Also, I have one plant where the bottom leaves died off and the stem is now approximatly 5 inches tall with no leaves on the bottom only on top. The stem looks like it has “thorns” where the leaves dropped off from. What could cause this ??
African violet

First, let’s talk about blooming. Hard to say why one blooms and not the other. Violets tend to bloom when slightly pot bound. They need bright indirect light (East window) throughout the year and temperatures ranging from 60-80 degrees. In order to bloom, violets should receive no more than 16 hrs of light/day. Saintpaulias will grow with as little as 3 hrs of light per day. Conversely, they need at least 8 hrs of darkness to trigger blooming. The soiless mix that they are planted in have little nutrients and need to be supplemented, therefore feed it with a balanced liquid fertilizer (20-20-20) at 1/4 strength every time you water. Avoid fertilizer with urea which can cause root burn, pale leaves and reduce blooming. Another old suggestion is to sprinkle epson salts (magnesium sulfate) on top of the soil and water it in. Apply it once and it may take a month to see results.

When the lower leaves die back, they produce a “bare neck” look; to remedy this take the dull end of a knife and scape off the dead tissue along the stem, then repot so that the leaves line up with the edge of the pot and fill with soil.

    Hello, I have a question for you. Im currently having a problem with little bug in the soil of my plants. can you tell me how to get rid of them out of the soil ? Also how to make African violets bloom

    A common bug in household plants is the fungus gnat. It occurs in moist soil and likes to feed on peat moss, leaf mold and small roots which usually doesn’t affect adult plants. Let the soil dry out between waterings to reduce populations. In addition you can use yellow stick cards which trap the adults and/or BT israelensis that goes under several product names Knock-Out Gnats and Gnatrol. Mix according to label directions and use as a soil drench. Water the solution until it drain from the bottom. Lack of flowers on African Violets usually are the result of either not enough fertilizer or light. Feed your plant with a low dose of fertilizer every time you water. Use 1/4 tsp of fertilizer to 1 gal of water, try Peters African Violet (12-36-14) formulated for blooming or a balanced fertilizer (20-20-20). Give it bright filtered light.

    Hello, now I would like to know if it is time to cut back my mandevilla plant. it already has some vines with leaves on it.. what should I do to start it to grow for the season ?? also, i have african violets the when the bottom leaves die and I trim them leaves a long ugly stem then the leafs are green on top ? should I transplant, cut the stem up to the leaves or what.. please help thanks again

    You can cut it back up to 1/2 . It blooms on old wood and should bloom this summer. Even when cut almost to the ground, it will bloom the same year from the new shoots. It responds to warm temperatures above 65 degrees. Once you see a new flush of growth feed with a 10-20-10 fertilizer to encourage blooming. The bare neck syndrome says its time to replant your violet. Do not cut the stem. Scrape off the dried tissue on the bare stalk and replant so the lower leaves rest at the top of the pot and fill in with soil.

    I never can keep my violets flowering. no matter where I put it or water or just care for it. I have never had any luck with them and i want to know why..and what can I do to have them flower

    Hi
    African violets generally will not bloom all the time but there are some things you can do to encourage them to bloom. See the above article on blooming.

  • Dawn

    I have started new African Violets from leaf cuttings. The plants appear to be health but they have never bloomed. All my other violets bloom very well, just not the ones started from leaves. What do they need?

    Sometimes it takes a year from leaf cutting to bloom for an African Violet. If all other variables are the same; amount of light (bright not hot, east window,) fertilizer (12-36-14) and soil type(well drained), then it must be a matter of time.

    When the flowers die on my African violet, do I cut them off or let them rot off?

    Remove dead flowers immediately, it will encourage more blooms and minimize the spread of pathogens. If flowers are left to rot they can under the right conditions spread the pathogen to other parts of the plant. When grooming your plant also remove any damaged or dying leaves and check for insects.

  • Brenda

    Our violets, over the summer, were blooming constantly and very sturdy. Suddenly, the leaves are turning brown and wilted looking. What can be causing this and what do we do to correct the situation? Thank you.

    You may want to check on the watering technique. African violets don’t like soggy soil which can lead to root and crown rot. They need less water in the winter. Be sure not to overwater. http://www.ppath.cas.psu.edu/EXTENSION/PLANT_DISEASE/afviotet.html

    For a very long time I have used Peter’s A.V. Food. I ran out and went looking for more, and could not find it anywhere!! What happened?
    If for some reason they aren’t making it any more can someone recommend a new one to try. I don’t like the Miracle Grow!!
    Thanks,
    Cathy

    Have you tried Schultz AV food? It comes in a liquid form, easy to measure.

    I recently transplanted a beautiful 15 yr. old African violet into a ceramic self watering pot (which I made at ceramics class). Unfortunately during the transplanting the very long neck which had developed over the past several years broke leaving some root but losing most of the root ball. It has gotten soft, limp leaves but the flowers on it are OK. The soil is nicely moist and not soggy at all. Is this plant doomed? I hope not as my mother grew it especially for my granddaughter when she was just a little tot.

    Hi Anna
    Eventhough your violet is pouting for now I don’t think it is doomed. When transplanting a ” bare neck” violet the leaves should line up at the edge of the pot-not too high or too low. Keep it stress free and in filtered light until it rebuilds its new root system. You can also try to start a new plant from a leaf cutting just like your mother did.

    I have white sticky stuff on my plants
    what do i do???

    Is it on your African violet? Is it a white cottony fluff on the undersides and axils of the leaves? You might have mealy bugs.

    I have 2 healthy,
    mature African violets. Lately I notice that the some leaves have holes either chewed or “burned” into them. The holes are brown around the edges. I’ve noticed some white specks on the TOP of the leaves but not on the bottom. Since I recently had to treat a hibiscus plant in the same room for fungus (leaf mold), I’m wondering if it has contaminated my two violets. If so what should I do? These are very special plants to me because they were my late mother’s and I don’t want anything to destroy them. Thank you for your help.

    Is it possible that the violet leaves were splashed or sprayed with cold water?

  • Jackie Peterson

    I pre-mix the African violet food, so it is usually about room temperature when I feed my plants. I may have splashed the leaf with it, but I’ve done that before without injuring the plant. I bring them into the kitchen to water them. If somehow they were splashed with cold water, would it create a hole right through the leaf as though a critter was chewing on it? Do you have a comment regarding the white specs on the top of the leaves and the fungus on a plant in the same room? Since there are several leaves on both plants that have holes, I’m getting concerned. Would it be possible for me to email you a digital picture so that you could see what they look like? Thanks for your help.

    Hi Jackie
    After seeing your photos of the African violet, it looks like the holes in the leaves are chewed or have been physically damaged-leaf tear. Do you have a cat? If so, they like to nibble on plants in the home. I don’t see too many white specs on the leaves. They could be some inert substance (dust) try brushing them off with a fluffy cosmetic brush and see if they come off. If they develop into white powdery patches-then it may be powdery mildew a fungus which grows in cool, moist, stagnant air and fluctuating temperatures. Increase air circulation, keep humidity at less than 60% and maintain a constant warm temperatures that doesn’t vary more than 10 degrees. Optimara recommends a baking soda(has anti-fungal properties) solution (1tsp. of baking soda to 1 qt. of water) Spray the room temperature mix on the leaves. They also recommend spraying Lysol on the leaves. It can also be controlled with a fungicide; check the label to make sure its safe on African violets. . http://www.optimara.com/doctoroptimara/diagnosis/powderymildew.html
    Good luck, let me know what happens.

    We are growing African Violets at our office and 3 of the 5 plants are big beautiful and doing well. However 2 are small and limp. They don’t seem to be thriving and have a yellowish white crud on the soil, which by reading I can see is some type of mold. I was working on the one and adding some fertilizer and the whole plant came out in my hand. There doesn’t appear to be ANY root ball at all and tho the plant doesn’t appear to be dead I’m wondering if it is savable or do we need to chuck it and start over? There are other blooms on the big plant that we could re-plant. Is there anything you recommend? Thanks for any and all help you can give.

    Hi Liza
    The yellowish/white “crud” can also be soluble salt accumulation from fertilizer. If the leaves are healthy, you can try to propagate the leaves to produce new plants. In best conditions, it takes about 10 months from leaf cutting to a flowering plant. IF you have and stalk on the plant, you can try to reroot it; by first cleaning off the end of the stalk, (dust the end with a rooting hormone -optional) and then placing it in fresh moistened soil. Put the pot in a plastic bag and keep the plant in a warm sunny place. It should develop new roots in 6 weeks. The plastic bag will increase humidity, be sure to open it periodically so the heat doesn’t build up inside on a sunny day. Rooting hormone can speed up the rooting process.

    I wanted to find out how to keep my 40+ potted violets from drying out when I am away on vacation. Currently I water the plants once a week, by letting them soak for about an hour or more, till the top of the soil is moist. They do not have wicks, so what would be the best way to keep them moist? I will be away for about 20days & would hate to lose the plants in that time. There will be no-one checking in on them, & I need to ensure they remain moist. Thanks for any steps to help these plants from drying out.

    That’s a lot of violets! Your house is turning into a greenhouse. For your vacation care water your violet well just as you described above and place them in shallow dishes covered with pebbles or gravel and water added up to the top of the pebbles. The bottom of the pot should not touch any water otherewise use inverted shallow pot saucers. This will provide some humidity to the plants. Also drape a plastic tent over them to keep in some moisture.

    I have a question about my African Violet plants. Some of them are getting kind of “petrified” (for lack of a better word) at the center where the new leaves come from. The leaves are very tiny, hard, and clumped together. They are not growing and when you touch them they break off. The outer leaves seem OK. I’ve been growing African Violets successfully for years and have never seen this. It’s a new phenomenon. It started with one or two plants and now seems to be spreading to others. Can you help me identify this problem?

    Hi Frank
    One of the typical insect problems that African violets have is cyclamen mites. These are tiny insects, insivible to the naked eye. They feed in the new growth inside the center of the plant. Some of the symptoms are distorted, “corky” puckered or curly leaves and stunted growth.

    My africian violet plant was doing very well for years. I transplanted it to a bigger pot as it was getting to large for the current pot. It was doing ok for a few months and then it started to shrivel up and now has died. Is there any way to save the root and start up a new plant ?

    Hi Shirley
    The death of your African violet was most likely caused by some root damage, therefore I don’t think the roots would work to start a new plant. I’m not sure that its possible to start an African violet from roots.

  • Heather

    I have an African violet and it is very sparse and limp, it looks burnt in the center. i have used miricale grow on it and recently repotted it. Is there anything i can do to bring it back? PLEASE HELP!

    Hi Heather,
    Check the article African violet insect problem, I suspect you may have a cyclamen mite issue.

  • Ray

    I wanted to share something I read on getting the violets to bloom – squeeze the pot a few times, which seems to “shock” the plant into sending up blooms! I have tried it on mature plants, including snapping off leaves at the base, which has resulted in re-blooming! I also diligently follow the feeding routine (with Schultz liquid feed) every time I water, & all the plants, new & old, have beautiful shiny leaves that fan out quite nicely. Every one of my violets are in their original 4″ pot & I’ve re-potted the older ones, once a year only.
    Hope this helps some of the readers!

  • DORIS TULLER

    CAN I GROW MY AFRICAN VIOLETS IN A BRIGHT ROOM ON AN END TABLE. iT IS REALLY BRIGHT IN MY LIVING ROOM ON SUNNY DAYS. CAN YOU PUT THEM UNDER A LIGHT WITH JUST A REGULAR FLOURESCENT BULB. PLEASE HELP
    DORIS

    Hi Doris
    Yes, you can grow African violets in a bright room, as long as the plant isn’t in direct sun. South and west window is great in winter and east or north is best in summer. They can be grown under flourescent lights (20-40 watt tubes) but not incandescent bulbs. The should be 12-15 inches above the lights for 14-16 hrs per day.

  • Dorothy

    I have a miniature a. violet with white and lilac blooms some of which get brown edges. Is this indicative of a problem?
    Also, I received a violet mixed with other plants in one pot. I transplanted it to a large pot with other plants (not knowing then that violets like to be root bound). It blooms profusely, is in an east-facing window and gets direct sunlight! I live in Calgary so the winter light is week but even now it is thriving in June.

  • Holly

    I have four violets I inherited from my late mother. As a whole, my plants seem to be fine. The tips I’ve read today will make them better.

    I am however getting concerned because the leaves of the plants seem to be fading. They appear to be healthy (solid not mushy, no edges burnt or wilted), however they have lost a lot of their color. What am I doing wrong?

    A few of the plants appear to have baby shoots. Should these be pulled out of the pot and transplanted to a new one?

    Thank you for your kind assistance.

  • Stacey

    We have an african violet in our office. It appears that someone must have hit it and some of the roots have separated from the plant. It is looking very droopy and dark. Is there anything that can be done to save this plant? It has sentimental value to the president of our company.
    Thank you for any info you can offer.

  • Julie

    I started an AV plant from a leaf cutting; now I have 3-4 small new green leaves starting. But some of the leaf tips are getting brown edges. I have my AV on a window sill on the north side of my house. I have it in a small container with a hole in the bottom. I add about 1 tbsp. water ever few days to the tray. What am I doing wrong?
