About White Tiger Jaws
Faucaria candida · also called White Tiger Jaws, White-Flowered Tiger Jaws · houseplant
Faucaria candida is a small, clump-forming South African succulent with fleshy, toothed leaves arranged in opposing pairs that resemble an open jaw. It is distinguished from the common tiger jaws by its pure white autumn flowers with a yellow centre. It thrives in full sun with minimal water and a cool, dry winter rest.
Preferred mix: Well-draining cactus compost
Watch for — Root rot from overwatering: The 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.
Why white tiger jaws needs this mix
White Tiger Jaws is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- White Tiger Jaws is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons white tiger jaws struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates white tiger jaws's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for white tiger jaws.
pH — does it matter for white tiger jaws?
White Tiger Jaws is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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 decent bagged houseplant compost works for white tiger jaws as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all white tiger jaws needs — the free-draining mix does the rest.
Refresh white tiger jaws's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for white tiger jaws covers the timing and technique step by step.
