Toxicity is partly unassessed

  • Not assessed for cats. This plant is not on the ASPCA list. That is not a finding of safety: none of the sources read for this site gives an answer either way. Treat it as unknown.
  • Not assessed for dogs. This plant is not on the ASPCA list. That is not a finding of safety: none of the sources read for this site gives an answer either way. Treat it as unknown.
  • Not assessed for people. RHS publishes no harm statement for this plant. That is not a finding of safety: none of the sources read for this site gives an answer either way. Treat it as unknown.

How it usually goes wrong

Leaves turn glassy from the stem outward

The zebra haworthia leans in its pot as the tissue at soil level softens, and the lowest leaves drop whole.

Plants that store water in their tissue take it up readily and release it slowly. In soil that stays wetter than the well-drained its source describes, the stored tissue breaks down.

Telling it apart: Firm and wrinkled is thirst; soft and swollen is the opposite. The two look similar from across a room and feel nothing alike.

The whole plant sags between waterings

Posture goes before colour. A thirsty zebra haworthia looks deflated rather than diseased, and the compost has shrunk away from the side of the pot.

Stored water is spent before the plant gives up anything else, and the tissue creases as it empties. Its source describes well-drained soil, which assumes the store is refilled.

Telling it apart: Lift the pot. A plant that is light and sagging is thirsty; one that is heavy and sagging is not.

Whitened areas where the sun falls longest

Scorched leaves on the zebra haworthia turn from pale to brown and brittle, and the damage stops where the shade of another leaf fell across it.

Nothing here disputes the full sun its source names. The damage comes from the change: foliage formed in lower light is thin, and a sudden move into direct sun bleaches it faster than tougher growth can replace it.

Telling it apart: Whether it followed a move or a season. Scorch appears within days of a change in position.

Routine care

Watering
Do not overwater; let the soil dry between waterings, as too much water can lead to root rot.
NC State Extension · read 13 September 2026
During growth, water moderately and give a low-nitrogen fertiliser at half strength once or twice.

Feeding
While growing, water moderately and give a low-nitrogen fertiliser at half strength once or twice.
RHS · read 13 September 2026
Propagation
Zebra plant forms pups and offsets; separate the pups or detach the offshoots from the parent to make new plants. Leaf cuttings also work, and seeds are rarely used.
NC State Extension · read 13 September 2026
In spring, sow seed kept at 21-24°C; offsets can be separated, and leaf cuttings taken, in spring or summer.

Pruning
Pruning is not needed.

Pests and diseases
Mealybugs can occur. Diseases: usually none.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
