About Common Candelabra Tylecodon
Tylecodon wallichii subsp. wallichii · also called Common Candelabra Tylecodon, Pegleg Butterbush · houseplant
A winter-growing caudiciform succulent from South Africa's Western Cape and Namibia, prized for its knobbly grey-brown stem covered in prominent leaf-scar phyllopodia. It drops its leaves in summer dormancy, leafing out again in autumn. Needs full sun, fast-draining gritty soil, and dry summers. Highly toxic to pets and livestock.
Preferred mix: Very sharply drained cactus and succulent mix with extra grit
Watch for — Root rot in summer: Watering a dormant plant in summer is the most common cause of death. Ensure almost complete dryness during the leafless summer period and confirm pot drainage is unobstructed.
Why common candelabra tylecodon needs this mix
Common Candelabra Tylecodon 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.
- Common Candelabra Tylecodon 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 common candelabra tylecodon 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 common candelabra tylecodon; 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 common candelabra tylecodon 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 common candelabra tylecodon?
pH is not a concern for common candelabra tylecodon — 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 common candelabra tylecodon 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 common candelabra tylecodon 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 common candelabra tylecodon covers the timing and technique step by step.
