Haworthia
Haworthia
The haworthia is a small rosette succulent from South Africa, most often the species fasciata or attenuata, recognisable by its dark green leaves striped with small raised white bands. It is a perfect houseplant to start with: it needs little water, little space, and is content with good light without requiring scorching full sun, unlike the echeveria. In Belgium it is kept indoors all year, as it dreads frost. A bright corner, sparing watering and a free-draining soil are enough to see it thrive for years.
Light and exposure
The haworthia likes bright light but not scorching sun. That is what sets it apart from other windowsill succulents: in the wild, it often grows sheltered by rocks, in light shade. An east- or west-facing sill, or a bright spot set back a little from a south window, suits it very well.
It even tolerates partial shade, which makes it one of the few succulents acceptable away from a full south window. In direct, prolonged sun, especially behind glass in summer, its leaves redden, brown or become spotted. If it turns a dull red, that is a sign of too much sun: pull it back a little. Conversely, a haworthia that stretches and pales is short of light.
Watering
Like all succulents, the haworthia is grown with restraint. Water only when the substrate is dry all the way through, then give water freely and let the excess drain away. In the growing season, spring and summer, that means watering roughly every ten to fifteen days; in winter, space it out a lot, once a month or less.
Pour the water at the base, on the soil, without flooding the centre of the rosette where standing moisture invites rot. The classic sign of overwatering is leaves turning soft, translucent and yellowish. A haworthia forgotten for a few weeks always recovers; an overwatered haworthia rots and dies. When in doubt, wait.
Soil and repotting
The haworthia wants a free-draining soil that does not hold water. A potting mix for cacti and succulents works, and is even better if you add coarse sand, perlite or pozzolana for a third of the volume. The aim is the same as for its cousins: that water runs through fast and the roots never sit in moisture.
The pot must have a hole at the bottom. A container that is not too large is preferable, because a big volume of soil stays moist too long around a small plant. Terracotta, being porous, helps the substrate dry between waterings and limits the risk of root rot.
Temperature and humidity
The haworthia is happy in the normal temperatures of a home, between 18 and 24 degrees for much of the year. It appreciates a slightly cooler spell in winter, around 10 to 15 degrees, in a bright, little-heated room, which helps it mark its rest without suffering.
It does not tolerate frost. The haworthia is frost-tender and has no business outdoors during our winters in the Herve area. Unlike the echeveria that can go out in summer, the haworthia is grown more simply indoors all year: it does not need full sun, so it does not need a summer outing to stay handsome. Keep it sheltered, indoors, from 1 January to 31 December.
Pruning and upkeep
The haworthia is not pruned. It is a slow, compact plant that does not run like the large succulents, so care is limited to cleaning up. Gently remove the leaves at the base as they dry and brown, which is natural with age, to keep the rosette tidy and avoid mould.
If a flower stalk appears, a long slender stem bearing small discreet flowers, you can cut it at the base once it has finished flowering, as it is barely decorative and tires the plant for nothing. Otherwise, there is nothing to cut: the haworthia is content to be left alone.
Pests and diseases
The real risk, here again, is not a disease but too much water. A haworthia that softens, whose leaves turn transparent and yellow at the base, is suffering from overly generous watering and a soil that does not dry. It must then be taken out of the pot, the roots and rotten parts removed, left to dry and repotted in fresh, free-draining substrate.
On the pest side, watch for mealybugs, small white cottony clusters lodged between the leaves and at the collar, to be removed with a cotton bud dipped in alcohol. Root mealybugs can also settle in a substrate that has stayed too moist. A plant set in decent light and watered sparingly generally stays free of any problem.
Propagation
The haworthia propagates mainly through its offsets, called pups, those small rosettes born at the base of the mother plant. Just unpot the plant, detach a well-formed offset with a few roots if possible, let the cut dry for a day or two, then replant it in a small pot of free-draining substrate. It is the most reliable and quickest method.
Leaf cuttings are possible but less consistent than with the echeveria: detach a whole leaf at the base, let it callus, lay it on barely damp soil and arm yourself with patience, as rooting is slow and does not always succeed. For a beginner, separating the offsets remains the surest way to enlarge a collection.
Local know-how
In Belgium (Herve climate, zone 8a)
In the Herve area, the haworthia is the no-fuss succulent: it lives indoors all year and asks for no schedule of going out or coming in. As it does without full sun, there is no point in moving it outdoors in summer; leave it in its place, on a bright but not full-south sill, where it drifts through the seasons quietly. That is what makes it an ideal plant for a beginner, a small flat or an office corner set back from the window.
Our grey winters are its only real constraint, and it handles them well. Cut watering sharply from November to February, when the light drops and the plant goes to rest: soaked soil in a heated room is the one sure way to lose it. If you have a bright, cool room, it will spend a better winter there than in the overheated living room. When the fine days return and the light comes back, gradually resume watering and, if needed, repot or separate the offsets gathered at the base.

Identify my plantMonth-by-month care calendar
| January | Winter rest indoors. Very rare watering, once in the month at most. Set the plant in the brightest spot available to make up for the short days. |
|---|---|
| February | Still at rest. Keep watering drop by drop. Turn the pot now and then so the rosette stays even towards the light. |
| March | The light climbs again, growth restarts gently. Resume light watering when the soil is thoroughly dry. Good time to repot and separate the offsets if the pot is crowded. |
| April | Active growth. Water a little more regularly, always at the base and without soaking. Check that the light stays bright but without scorching sun behind the glass. |
| May | Full indoor season. A good time to propagate by separating the pups, which take quickly with the returning warmth. Watch that the spring sun does not burn the leaves. |
| June | Steady growth. Water freely but spaced out, letting it dry completely in between. If a flower stalk rises, leave it or cut it to your taste. |
| July | High summer. Beware of direct sun behind hot glass, which can scorch the haworthia: move it a little from the window if the leaves redden. |
| August | A fine time to take cuttings and separate the offsets. Keep watering sparing and watch for mealybugs between the leaves. |
| September | The days shorten, growth slows. Start spacing out watering. Clean up the dry leaves at the base. |
| October | Gradual entry into rest. Cut water back clearly. The plant stays indoors, it never had to go out anyway. |
| November | Winter rest settled in. Rare watering. A bright, cool room beats an overheated, dark living room for getting through winter. |
| December | Full rest. Almost no water, maximum light. Leave the plant alone while waiting for the long days to return. |
Green Hub tips
- Unlike the echeveria, the haworthia does not like scorching full sun: bright light or even partial shade is enough for it.
