African Violets are delightful houseplants and will brighten up any room with their purple, pink, or white colors.
Planting
How to Plant African Violets
- You can use an African violet–specific potting mix or an all-purpose potting mix, as long as it is well-draining. Here’s how to create your own mix.
- Keep African violets planted in small pots and repot every few years in fresh potting mix. Being a bit pot-bound encourages African violets to bloom more, so don’t be too quick to give them more space.
- The potting mix should be loose and well-draining; high organic matter content is a plus. Learn about organic soil amendments.
- When repotting African violets, don’t plant them any deeper than they were planted previously, and be careful not to bury the crown. African violets‘ stems can be susceptible to rot if kept too moist.
Growing
How to Care for African Violets
- According to Julie Weisenhorn, an Extension educator at the University of Minnesota, “If you are comfortable, your African violet is comfortable.” Optimal room temperature for growing African violets is between 60° and 80°F and ideally 70°F.” However, some are more tolerant of cooler conditions. In any case, keep them away from drafty windows in winter.
- Plants should be shifted to larger pots as they grow, but keeping African violets slightly root-bound can encourage them to bloom. One sign that your violet needs repotting is wilted leaves.
- The fuzzy leaves have a tendency to collect dust and dirt. Brush them off gently with a small, soft-bristled paintbrush.

African Violet Troubleshooting Chart
| Problem | Likely Cause | Solution |
|---|---|---|
| No flowers | Too little light; too much nitrogen; plant too cold | Move to bright, indirect light; switch to a bloom-boosting fertilizer; keep temps 65°–75°F |
| Leaves turning yellow | Overwatering; poor drainage; old leaves | Allow soil to dry slightly between waterings; use a pot with drainage; remove aging outer leaves |
| Wilting leaves | Root rot or underwatering | Check soil moisture; trim rotted roots and repot in fresh mix; water consistently |
| Mushy or collapsing crown | Crown rot from cold water or water sitting on leaves | Water from the bottom; avoid splashing leaves; keep water lukewarm |
| Brown leaf spots | Cold water; sun scorch | Use room-temperature water; keep out of direct sunlight |
| Pale or stretched leaves | Insufficient light | Move plant closer to a bright window or use grow lights |
| Curled or brittle leaves | Low humidity; cold drafts | Increase humidity with a tray or humidifier; move away from vents |
| White crust on soil | Salt buildup from fertilizer or hard water | Flush soil monthly with distilled water; fertilize lightly |
| Slow growth | Root-bound plant; nutrient deficiency | Repot every 6–12 months; fertilize regularly at low strength |
| Flowers fade quickly | Heat stress; dry air | Keep temperatures moderate; increase humidity |
Use room-temperature water, as chilled water can leave marks on the leaves.
Leaves are susceptible to rot and fungal spots if kept in high humidity, so water African violets from the bottom to avoid getting excess water on the foliage.
Artificial lighting works well, too. Use fluorescent or LED bulbs to supplement natural lighting.
Thin, dark green leaves and leggy stems tell you the plant is getting too little light; light green or bleached leaves indicate too much light.
Overfertilizing is a more common problem than underfertilizing since most potting mixes come infused with plenty of nutrients.
Types
Hundreds of varieties and hybrids exist, from miniature violets to trailing varieties! They differ mainly in the colors of their flowers, which range from white to purple, though some varieties also have variegation in their foliage and flowers.
African violets are typically classified by size, based on how wide they grow:
- Miniature: less than 8 inches across
- Standard: 8–16 inches across
- Large: more than 16 inches across

Make sure that you don't overwater and that the soil drains well. If you have the African violet in a bright window move it to a spot with indirect sunlight for a while. If you are using tap water for watering you may want to switch to bottled water and see if that helps. Many public water supplier use chloramine to treat the water and there are concerns that chloramine may cause African violets not to thrive and leaves turn yellow or brown.
Hi Jean, You may enjoy this other article about African Violets: http://www.almanac.com/blog/gardening/gardening/african-violets
Hi, Anne: Generally, it's not a good idea to repot an African violet in a larger pot. It's hard to tell whether what you are talking about here is the root or actually the stem, but in any event, this plant needs to be cut back and replanted back into a smaller pot or pots. See the African Violet Society link in the Reply of September 2 preceding this and follow the instructions for repotting a long neck, even if indeed you are dealing with a root extension, too (which would need to be cut off). Good luck!
This is a common problem with older African violets and is sometimes called "turkey neck". Please see the link below from the African Violet Society for step by step instructions on how to remove the top section of the plant and replant the stem. Click on "How to repot a long neck".
