About Bear Paw
Cotyledon tomentosa · also called Bear Paw, Bear's Paw · houseplant
Bear Paw (Cotyledon tomentosa) is a small South African succulent with plump, fuzzy green leaves tipped by tooth-like red "claws." Give it bright light, gritty fast-draining soil, and soak-and-dry watering. It is not ASPCA-listed but the Cotyledon genus contains cardiac-glycoside toxins, so treat as toxic to pets.
Preferred mix: Gritty, fast-draining cactus/succulent mix
Watch for — Root rot from overwatering: The most common killer. Soggy soil turns leaves and stems soft, mushy and translucent. Use gritty mix, a pot with drainage, and let soil dry fully between waterings — especially in winter.
Why bear paw needs this mix
Bear Paw 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.
- Bear Paw 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 bear paw 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 bear paw; 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 bear paw 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 bear paw?
pH is not a concern for bear paw — 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 bear paw 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 bear paw 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 bear paw covers the timing and technique step by step.
