How to care for an African violet (Saintpaulia)
Streptocarpus sect. Saintpaulia
An African violet rewards a steady routine: bright indirect light, a warm room, and tepid water given from below so the fuzzy leaves stay dry. Water splashed on those hairy leaves leaves pale rings and can rot the crown — that, plus cold, is what does most of them in. Done right, it can flower nearly year-round.
Care at a glance
- Light
- Bright but filtered light, never harsh sunAn east or north window suits it; a few hours of gentle morning light is fine, but strong midday sun bleaches and scorches the leaves. Leggy growth means it wants more light.
- Water
- From below, with tepid water, when the surface driesStand the pot in a saucer of room-temperature water for 20–30 minutes, then tip away what is not drawn up. Cold water and wet leaves both cause trouble.
- Soil
- Light, free-draining African violet mixA peat-free houseplant compost loosened with perlite works; the roots are fine and dislike being waterlogged.
- Humidity
- Moderate room humidity is enoughAvoid misting — water sitting on the leaves is exactly what you are trying to prevent.
- Temperature
- 18–24 °C (65–75 °F), steadyKeep it away from cold glass in winter; it dislikes chills and sudden swings.
- Difficulty
- ModerateEasy to keep alive, but flowering well depends on getting light and watering just so.
- Pets
- Non-toxic to petsNon-toxic to cats and dogs (ASPCA). Pesticide-treated shop plants are the only real caution; a nibble of an untreated plant is harmless beyond possible mild tummy upset.
Where it comes from
Propagation
African violets root beautifully from a single leaf. Cut a healthy mature leaf with about 3 cm of stalk, push the stalk into damp, gritty compost at an angle, and keep it warm and covered loosely to hold humidity. In six to eight weeks a cluster of tiny plantlets appears at the base, which you separate and pot on once they have a few leaves of their own.
Common problems
- Pale rings or spots on the leaves
Likely cause: Cold water touching the leaf surface in bright light.
Fix: Always water from below with tepid water and keep droplets off the foliage.
- Lush leaves but no flowers
Likely cause: Too little light, or a pot so large the plant pours its energy into roots and leaves.
Fix: Move it to brighter filtered light and keep it slightly pot-bound — these bloom best with their roots a little snug.
- Mushy, collapsing crown
Likely cause: Crown rot from water pooling in the centre of the rosette.
Fix: Stop overhead watering immediately; if rot has set in, take healthy leaf cuttings to start fresh plants.
Frequently asked questions
Why won't my African violet flower?
The two usual reasons are too little light and too much pot. Move it to brighter filtered light and keep it in a snug container — these bloom best when slightly root-bound.
Can I mist my African violet to raise humidity?
Avoid it. Water resting on the fuzzy leaves causes pale blotches and can rot the crown. If the air is dry, set the pot on a tray of moist pebbles instead.
Why are my African violet leaves curling downward?
Downward-curling, dull leaves usually point to cold — a chilly windowsill or cold water. Move it somewhere consistently warm and water only with tepid water.
Are African violets poisonous to pets?
No — the ASPCA lists them as non-toxic to cats and dogs. The only caveat is that shop plants are sometimes treated with insecticides, so rinse and keep new plants out of reach until you know.
