Care at a glance

Light

In the wild haworthia grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Bright indirect light. Tolerates an hour of gentle direct sun but burns in harsh midday light. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Haworthia watering is mostly about restraint. When the soil is dry, every 2-3 weeks — and never on a schedule. The finger test (or the pot-lift test) catches the actual moisture state; a calendar assumes weather and light don't change. Water deeply and let the mix dry completely. Reduce sharply in winter.

Soil and pot

Haworthia grows best in gritty cactus mix. Standard cactus mix with extra perlite or pumice. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Haworthia sits happiest at around 30-50% humidity and 15-26°C (60-80°F). Average household air is fine. If you keep the room above 15 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed haworthia sparingly. Quarter-strength cactus feed every 6-8 weeks during the growing season. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on haworthia in the Growli community. Where a problem matches one of our diagnostic guides, click through for the full step-by-step recovery plan written for haworthia specifically.

  • Red or purple flush — Sunburn or cold stress — move to gentler light.
  • Soft translucent leaves — Overwatering and beginning of root rot.
  • Wrinkled leaves — Under-watering; soak once and resume normal schedule.
  • Pale washed-out leaves — Insufficient light; the stripes fade in deep shade.

Propagation

Offsets pulled from the base root readily after a 2-3 day callus period. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Haworthia is pet-safe. Haworthia species are listed by the ASPCA as non-toxic to cats and dogs. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Haworthia care — frequently asked questions

What is the common name for Haworthiopsis attenuata?

Haworthiopsis attenuata is most commonly called Haworthia, but it is also known as zebra plant, zebra haworthia, pearl plant. The names refer to the same species, so care instructions for Haworthia apply identically to anything sold as zebra plant.

How much light does haworthia need?

Haworthia grows best in bright indirect light (just back from a sunny window). Bright indirect light. Tolerates an hour of gentle direct sun but burns in harsh midday light.

How often should I water haworthia?

Water haworthia when the soil is dry, every 2-3 weeks. Water deeply and let the mix dry completely. Reduce sharply in winter. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is haworthia toxic to cats and dogs?

Haworthia is pet-safe. Haworthia species are listed by the ASPCA as non-toxic to cats and dogs.

What USDA hardiness zone does haworthia grow in?

Haworthia is rated for USDA zone 9-11 (indoor-only in most US homes) and RHS hardiness H1c. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
