Haworthia is a large genus of small succulent plants endemic to Southern Africa. Like the aloes, they are members of the subfamily Asphodeloideae and they generally resemble miniature aloes, except in their flowers which are distinctive in appearance. They are very popular garden and container plants.
Common name : Haworthia
Scientific name : Haworthia
Family : Liliaceae
Category : Indoor
Type of plant : Perennial
Haworthias are small succulent plants, forming rosettes of leaves from 3 cm (1.2 in) to exceptionally 30 cm (12 in) in diameter, depending on the species. The rosettes are usually stemless but in some species stems reach up to 50 cm (20 in). The plants can grow solitary or can be clump-forming. Most species have firm, tough, fleshy leaves, usually dark green in colour, whereas others are softer and contain leaf windows with translucent panels through which sunlight can reach internal photosynthetic tissues. Their flowers are small, white and very similar between species - but their leaves show wide variations even within one species.
The haworthia is very similar to Aloe, with its pretty fleshy, succulent, rosette leaves. It is a plant of South Africa, which must therefore be grown indoors. Its leaves are linear, sometimes broad, sometimes triangular, often covered with small pale "buttons" implanted regularly.
The flowers grow in summer, as clusters of small flowers in tube or funnel. There colors go from white to pink.
Plant my haworthia
Typically a mild climate plant, Haworthia adapts especially well to the interiors of our homes and apartments. It develops well between temperatures of 18-22°C (slightly cooler in winter, if possible), and it needs light. Be careful nonetheless. Avoid placing the plant directly behind a window with too much sun exposure!
Water my haworthia
Your haworthia dislikes humidity, and its water needs are pretty limited — it stores everything it needs inside its thick leaves!
During growth seasons (spring, summer), watering should be regular, about once or twice a month, but controlled, to make sure the roots don't rot. In autumn, gradually reduce watering until winter, when once-monthly watering will suffice.
Use soft (non-chalky) water, closer to room temperature than cold, as a significant temperature drop can cause serious stress to your plant.
Spray my haworthia
In dry weather, spray your plant with water not too hard, clean the dust on the leaves: it will be all the more beautiful!
Repot my haworthia
At the end of the winter every 3 or 4 years, repot your haworthia in a pot slightly larger than the current, with a mixture of sand and potting soil. Cover the root knot, but do not let the leaves touch the ground. Put the haworthia root knot just above the top of the soil! Do not water in the first days after potting: the roots damaged by repotting increase the chances of root rot. Wait a few days and water slightly the first two times.
Put outside my haworthia
Do not hesitate to take out your haworthia for the summer! Just avoid placing it directly in the midday sun, or too much in the shade - acclimate it gently, and of course, keep watering! You will bring it inside at the end of Summer.
Shelter my haworthia
Place your haworthia inside long before the first cool nights, in a room not too heated so that it "feels" the winter period: a cold around 5 to 10 ° C at night without artificial light! You should water once a month in winter.
Check on my haworthia
If leaves become flat and low, increase sun exposure. The leaves of the haworthia must push upward or outward angularly, towards the sunlight. If they tend towards the ground or they grow outward, it is because the plant probably does not get enough sun. Move it to a sunny spot. If it's inside, think about letting it out during the day! Conversely, if the leaves turn brown, reduce exposure to the sun. If the leaves are thin and curly, increase the watering! And if the leaves turn yellow or sag, stop watering. Yellowing or "crumbling" leaves suffer from excess water.
Hawworthia is not very sensitive to diseases, except when it is too watered. It can then suffer the attacks of mealybug. Mealybugs are sucking biting insects covered with a sort of waxy or powdery shell. You can take it off with a cotton swab dipped in alcohol if they do too much damage.
