Aloinopsis malherbei · also called Malherbe's aloinopsis · houseplant

Aloinopsis malherbei is a tuberous-rooted dwarf mesemb from the South African Karoo with broad, spoon-shaped grey-green leaves carrying pale marginal teeth. A winter grower, it opens yellow daisy-like flowers in the cool season. It demands very sharp drainage, full sun and a near-dry summer rest, with all real watering concentrated in autumn through spring.

Mature size: Small: leaves reach roughly 4-6 cm long, rosettes around 8-12 cm across, slowly clumping wider with age but staying low and ground-hugging.

Watch for — Root rot: The fleshy taproot rots quickly in wet or heavy soil, especially in summer. Use a gritty mix, water only when fully dry, and keep nearly dry during dormancy.

How to tell aloinopsis malherbei needs repotting

Repotting on a calendar is less reliable than reading the plant. For aloinopsis malherbei, watch for these signs:

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that aloinopsis malherbei bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot aloinopsis malherbei

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, aloinopsis malherbei is lifted and divided once the clump congests and flowering drops off. A stemless, clump-forming dwarf succulent producing rosettes of broad, spatula-shaped toothed leaves over a thick tuberous root; slowly forms small mounds..

What size pot to step aloinopsis malherbei up to

Pot size matters less than depth and spacing here. When you replant aloinopsis malherbei, set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot aloinopsis malherbei

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing aloinopsis malherbei in full growth or flower sets it back badly.

Step-by-step: repotting aloinopsis malherbei

Wait for dormancy. Let aloinopsis malherbei foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh gritty, free-draining mineral mix at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting aloinopsis malherbei, keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for aloinopsis malherbei

Aloinopsis malherbei wants gritty, free-draining mineral mix. Blend cactus compost roughly half-and-half with pumice, grit or perlite, and use a deeper pot to accommodate the taproot. Lean, mineral, fast-draining soil reflects its rocky habitat; rich water-holding mixes cause rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting aloinopsis malherbei — frequently asked questions

How often should you repot aloinopsis malherbei?

Lift and divide every 3–4 years once clumps congest for aloinopsis malherbei. Aloinopsis malherbei is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in gritty, free-draining mineral mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does aloinopsis malherbei need?

When is the best time of year to repot aloinopsis malherbei?

Do you "repot" aloinopsis malherbei, or lift and divide it?

You lift and divide it. Aloinopsis malherbei grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise aloinopsis malherbei after repotting?

Hold off feeding aloinopsis malherbei until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
