African violet care: watering, light and repotting
Also called saintpaulia · Streptocarpus ionanthus · Gesneriaceae family
9 d in winter
How often to water the African violet?
Allow about 6 days between waterings in spring and summer, and 9 days in autumn and winter, when growth slows down. These rhythms apply to a room with its favourite light: in a darker room the plant drinks less; in a brighter one, it drinks more.
Water from the saucer with lukewarm water: cold water marks its hairy leaves. It flowers best when slightly pot-bound.
What light does it need?
The African violet likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Repotting and fertiliser
Repot every year, ideally in April, into a pot only slightly bigger than the last one. As for fertiliser, from March to October, feeding every 3 weeks is enough; the rest of the year, let it rest.
Adult size: 4–6 in (10–15 cm).
Safe for cats and dogs, according to the ASPCA.

Frequently asked questions
How often should you water the African violet?
About every 6 days in spring and summer, and every 9 days in autumn and winter, in a room with its favourite light. The darker the room, the longer you wait between waterings. Before watering, check that the top inch of soil has dried.
Where should you put the African violet?
The African violet likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Should you mist the African violet?
There's no need: indoor air suits it. Wetting its leaves for no reason can even encourage disease.
When should you repot the African violet?
Every year, ideally in April, or sooner if roots come out of the drainage hole. Choose a pot only slightly bigger, 1 to 1.5 in (2 to 4 cm) wider, always with a hole in the bottom.
Cats, dogs, children: is the African violet safe?
The African violet is listed as non-toxic to cats and dogs by the ASPCA. A pet that eats a lot of it may still vomit, so it's best not to let it nibble.
Is it an easy plant to care for?
Fairly: the African violet needs a little attention, mostly with watering and light. Nothing complicated with a reminder at the right time.
These are guidelines for an indoor plant in a temperate climate. Trust the soil too: a finger pushed an inch into it will tell you whether it's thirsty.
