Care at a glance

Light

White Tiger Jaws needs sun on the leaves, not just bright ambient room light. Requires at least 4–6 hours of direct sunlight daily for compact growth and reliable flowering. A south-facing windowsill is ideal. Insufficient light causes etiolated, weak growth and suppresses flowering. Protect from the very hottest summer sun if behind glass, where heat can build. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water white tiger jaws every 14–21 days during the growing season (spring–autumn); once monthly or less in winter. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water moderately during active growth, allowing the soil to dry completely between waterings. Like most mesembs, it tolerates drought well. In winter keep almost completely dry — a very occasional light watering prevents total desiccation but excess moisture in cool conditions causes rot.

Soil and pot

White Tiger Jaws grows best in well-draining cactus compost. Grow in a proprietary cactus compost or blend 2 parts standard potting mix with 1 part coarse grit or perlite. Fast drainage is essential; standing water at the roots, especially in winter, is fatal. Terracotta pots are preferred over plastic. 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

White Tiger Jaws sits happiest at around 20–40% humidity and 7–35°C (45–95°F). Tolerates typical low indoor humidity well. Avoid high-humidity environments such as bathrooms or poorly ventilated rooms. Good air circulation reduces the risk of fungal issues. If you keep the room above 7–35°C 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 white tiger jaws sparingly. Apply a dilute, balanced or low-nitrogen cactus fertiliser once a month during active growth (spring through early autumn). Do not feed in winter. 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 white tiger jaws in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Root rot from overwateringThe most common problem, especially in winter. The base of the plant becomes mushy and the leaves collapse. Always let soil dry fully between waterings and reduce watering to near-zero in cool months.
  • No flowersFaucaria candida flowers reliably in autumn only with sufficient direct sunlight through the growing season. Plants kept in low light or watered heavily in summer often skip flowering. Move to the sunniest available spot from spring onwards.
  • MealybugsWhite cottony masses appear in the crevices between leaf pairs. Treat promptly by removing bugs with a cotton swab dipped in isopropyl alcohol and, for heavier infestations, apply a systemic insecticide or neem oil.

Propagation

Division of offsets in spring or autumn — gently separate rooted offsets and pot into gritty compost, allowing cut surfaces to callous for 24 hours before potting. Seed can be sown in spring or autumn at 10–20°C on a gritty, barely moist surface. 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

White Tiger Jaws is mildly toxic to pets. Faucaria candida is not individually listed by ASPCA. Faucaria belongs to the Aizoaceae family, which has no widely documented toxic compounds, but the species has not been formally assessed for pet safety. Treat with caution and keep out of reach of pets and children as a precaution. 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.

White Tiger Jaws care — frequently asked questions

What is the common name for Faucaria candida?

Faucaria candida is most commonly called White Tiger Jaws, but it is also known as White Tiger Jaws, White-Flowered Tiger Jaws. The names refer to the same species, so care instructions for White Tiger Jaws apply identically to anything sold as White-Flowered Tiger Jaws.

How much light does white tiger jaws need?

White Tiger Jaws grows best in direct sun (at least 4-6 hours). Requires at least 4–6 hours of direct sunlight daily for compact growth and reliable flowering. A south-facing windowsill is ideal. Insufficient light causes etiolated, weak growth and suppresses flowering. Protect from the very hottest summer sun if behind glass, where heat can build.

How often should I water white tiger jaws?

Water white tiger jaws every 14–21 days during the growing season (spring–autumn); once monthly or less in winter. Water moderately during active growth, allowing the soil to dry completely between waterings. Like most mesembs, it tolerates drought well. In winter keep almost completely dry — a very occasional light watering prevents total desiccation but excess moisture in cool conditions causes rot. 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 white tiger jaws toxic to cats and dogs?

White Tiger Jaws is mildly toxic to pets. Faucaria candida is not individually listed by ASPCA. Faucaria belongs to the Aizoaceae family, which has no widely documented toxic compounds, but the species has not been formally assessed for pet safety. Treat with caution and keep out of reach of pets and children as a precaution.

What USDA hardiness zone does white tiger jaws grow in?

White Tiger Jaws is rated for USDA zone 10–11 and RHS hardiness H1c. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
