African violet, the most grown flower on the planet!
·
0
Violet-like blooms rise over low evergreen foliage, and they keep coming for most of the year, sometimes right through it — this is the African violet (Saintpaulia ionantha), one of the most sold indoor plants the world over. Give it veiled light with no direct sun on its leaves, ever, and the flowering barely stops.

Planting, repotting African violet
African violet likes a tight fit in its pot and thus doesn’t need to be repotted immediately.
After that, every 2 or 3 years and preferably in spring, repot your African violet in a pot of a very slightly larger size.
Repotting African violet
Check the new pot has a drainage hole
Surrounding temperatures must be lower than 60°F (16°C) to ensure proper settling in.
African violet roots hate having too much water. Double-check that the new pot has a hole in the bottom. Increase drainage with a layer of gravel or clay pebbles along the bottom of the pot, to make water flow through more easily.
Good soil mix is needed.
The plant, when it lives indoors, needs soil mix because that is the only source for the nutrients it needs.
Low but constant moisture levels must be maintained, without wetting the leaves.
You must rest the pot on a bed of gravel, rocks or clay marbles doused in water.
The best location for your African violet is in a spot where there isn’t any direct sun on the plant, ever.
Direct sun on the leaves is never tolerated
African violet can’t stand the sun’s rays when they touch its leaves directly.
So the plant rejoices in adequate light but not direct sun.
Absolutely avoid setting it near heat sources such as radiators, because moisture is what this tropical plant needs most.
African violet requires temperatures that oscillate between 65 and 74°F (18 to 24°C) and which never drops below 57°F (-13°C). Ideally, the daily cycle is 4 to 5 degrees cooler at night.
You can put gloxinia in the immediate vicinity of this plant because they both share the same growing conditions.
Watering and fertilizer to provide African violet with
Regular but moderate watering is called for. African violet requires little water.
In spring and summer
Keep the soil mix a bit moist and check that water drains properly.
Provide flower plant liquid fertilizer more or less once a month to extend the blooming to the max.
Water from above, ideally with water that is already at room temperature.
Never wet the leaves and flowers of your African violet.
To retain a certain moisture level, it is best to put the pot on a bed of clay pebbles with water at the bottom.
In fall and winter
Reduce watering and wait for the soil to be thoroughly dry in the surface before watering again.
Stop adding fertilizer.
African violet care, point by point
The five things that decide whether an African violet keeps flowering are light, temperature, watering, feeding and pot size. Here is what each one asks for.
African violet care, point by point
Care point
What to provide
Key precaution
Light
Plenty of veiled, indirect light
Never any direct sun on the leaves
Temperature
65 to 74°F (18 to 24°C), 4 to 5 degrees cooler at night
Keep away from radiators and other heat sources
Watering
Regular but moderate, with water at room temperature
Never wet the leaves and flowers
Fertiliser
Liquid flower plant fertiliser about once a month
Stop feeding in fall and winter
Repotting
A pot only very slightly larger, in spring
Only every 2 or 3 years, as the plant likes a tight fit
Get these five right and the blooming can stretch across most of the year.
If the color of the leaves turns pale, it is probably due to a lack of fertilizer.
Leaves that grow smaller and smaller in size show that you need to consider repotting your African violet.
Pale rings or spots on African violet leaves are often cold-water damage, though yellow blotches can have other causes, so water with room-temperature liquid and blot any stray drops from the foliage.
A crown that turns soft and brown while outer leaves wilt often signals crown or root rot, which overwatering encourages though fungal or bacterial pathogens may also be involved; empty the saucer after watering and never let the pot stand in water.
Keep a newly bought African violet apart from your other plants for a few weeks and inspect the leaf undersides and crowns, since mealybugs and cyclamen mites are far easier to stop on one plant than on a whole windowsill.
All there is to know about African violet
African violet or Cape violet was discovered in 1892 by Baron Walter Von Saint-Paul in the mountain ranges of Tanzania.
The name “Violet” was given to it because it is very similar to the viola violet, but there is otherwise nothing in common between the two plants.
African violet belongs to the Gesneriaceae family, alongside gloxinia and streptocarpus, so these relatives can share the same shelf, the same veiled light and the same careful watering routine.
African violet leaves are covered in fine hairs that trap water droplets on the surface, and splashed foliage can develop pale rings or spots, commonly attributed to cold water, while prolonged wetness invites rot.
Dust on hairy leaves is best brushed off with a soft, dry brush; if water is used, keep it lukewarm and let leaves dry out of direct sun, since cold water can spot foliage.
In plants such as African violets, peperomias and some begonias, a healthy mature leaf cut with a short petiole and set in moist mix will form young plantlets at the petiole’s base.
