About Tiger Jaws
Faucaria tigrina · also called Tiger Jaws, Tiger's Jaw · houseplant
Tiger Jaws (Faucaria tigrina) is a small clumping South African succulent whose paired triangular leaves bear soft tooth-like spines resembling open jaws, topped by yellow autumn flowers. Give it bright light, gritty fast-draining mix, and sparing water. It is not ASPCA-listed; treat as mildly toxic and verify with your vet.
Ideal humidity: 30-40% (low, average room humidity)
Watch for — Soft, mushy, translucent leaves: The classic sign of overwatering and rot. Let the soil dry fully between waterings, water far less in winter, and ensure the pot drains freely.
The watering schedule, season by season
Tiger Jaws stores water in its thick leaves and stems, so when in doubt, wait — it survives drought far better than soggy soil. The base rhythm for tiger jaws is every 2-3 weeks in spring-autumn; roughly monthly or less in winter, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: soak fully, then leave it alone until the soil is dry all the way down — usually around every 2-3 weeks.
- Autumn (slowing down): Autumn: ease off as growth slows; stretch the gap noticeably longer than the summer rhythm.
- Winter (rest / dormancy): Winter: water sparingly, roughly once a month or even less in a cool room. The thick leaves carry it through.
Water thoroughly, then let the soil dry out completely before watering again - this is a classic 'soak and dry' succulent. Cut right back in the winter rest period, giving only enough to stop the leaves shrivelling. Overwatering and standing moisture are the main killers, causing soft, mushy, rotting leaves and root rot. Always tip away water that collects in the saucer.

How to tell tiger jaws needs water
A calendar is the worst way to water tiger jaws. Check the plant and the soil instead — for this species, look for these signals in order:
- The lower or oldest leaves feel slightly soft or look a touch wrinkled.
- The pot is noticeably light when lifted.
- Soil is dry several centimetres down, not just at the surface.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering tiger jaws for a day is almost always safer than over-watering it.
Overwatering vs underwatering tiger jaws
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For tiger jaws specifically:
Signs you are overwatering
- Leaves turn translucent, yellow, soft and mushy — classic overwatering.
- Lower stem darkens or goes squishy at soil level.
- Whole rosettes or sections drop at the lightest touch.
Signs you are underwatering
- Leaves pucker, wrinkle or curl inward — a harmless thirst signal that reverses fast after a soak.
- Older leaves dry crisp from the tips first.
Overwatering is the number-one killer of tiger jaws. The thick leaves are a water tank — a slightly thirsty plant recovers in a day; a waterlogged one rots from the roots up.
Water quality notes
Tap water is generally fine for tiger jaws; the soak-and-dry rhythm matters far more than water type.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For tiger jaws, the levers that matter most are:
- A gritty, free-draining mix is essential — ordinary potting soil holds too much water for this plant.
- Terracotta dries faster and is more forgiving than plastic or glazed ceramic.
- More light and warmth speed drying, so the interval shortens in peak summer — always check, never assume.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of tiger jaws.
