About Few-Toothed Tiger Jaws
Faucaria paucidens · also called Few-Toothed Tiger Jaws, Tiger Jaws · houseplant
Few-Toothed Tiger Jaws is a dwarf succulent from South Africa's Eastern Cape with thick, glossy green leaves edged by fewer, more widely spaced white teeth than its relatives. Yellow, daisy-like flowers appear in late summer to autumn. It demands full sun, fast-draining gritty soil, and a near-dry winter rest.
Preferred mix: Gritty cactus or succulent mix
Watch for — Root and crown rot: Excess moisture, especially in the cooler months, causes rapid rotting at the crown and roots. Remove affected tissue, dust with sulphur powder, allow to dry for several days, then repot into fresh dry, gritty compost. Prevention through controlled watering is easier than cure.
Why few-toothed tiger jaws needs this mix
Few-Toothed Tiger Jaws stores water in its leaves and stems, so it wants a free-draining, gritty mix that dries out fully between waterings — not a moisture-holding one.
- Few-Toothed Tiger Jaws carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
- Its roots are adapted to short wet spells followed by long dry ones — a mix that stays damp removes the dry phase they depend on.
- A gritty mix also keeps the plant compact and well-coloured rather than soft, leggy and prone to collapse.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons few-toothed tiger jaws struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Standard potting compost on its own stays wet far too long for few-toothed tiger jaws; the lower leaves and stem base go soft and translucent first.
- Big plastic pots full of dense mix hold a wet core long after the surface looks dry — that hidden wet zone is where rot starts.
- Anything sold as "moisture control" is the opposite of what this plant wants.
Treating few-toothed tiger jaws like a leafy houseplant and using plain compost. It needs at least half its volume as grit, perlite or pumice to survive long term.
pH — does it matter for few-toothed tiger jaws?
pH is not a concern for few-toothed tiger jaws — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good bagged "cactus and succulent" mix works for few-toothed tiger jaws if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Drainage and the pot
Use a pot with a drainage hole and empty the saucer within minutes of watering. Terracotta is more forgiving than glazed or plastic because it dries the rootball faster.
This mix decomposes slowly, so few-toothed tiger jaws only needs repotting every 2-3 years — mainly to refresh the grit and check the roots are firm and pale. When the time comes, our repotting guide for few-toothed tiger jaws covers the timing and technique step by step.
