About Buchholz's Tylecodon

Tylecodon buchholzianus · also called Buchholz's Tylecodon, Pork Butterbush · houseplant

A compact, slow-growing succulent from the coastal deserts of Namibia and the Richtersveld, notable for its swollen, gnarled stem that photosynthesises through smooth green bark and rarely produces its short-lived cylindrical leaves. Winter-growing and nearly leafless through summer. Prized by caudiciform collectors. All Tylecodon are toxic — handle with care and keep away from pets.

Mature size: Up to 30 cm (12 in) tall and 25 cm (10 in) wide after many years

Watch for — Root rot: Very susceptible due to its desert-fog adaptation. The slightest overwatering in warm, humid conditions causes rapid root collapse. Use terracotta, fast-draining mix, and withhold water completely during warm summer months.

How to tell buchholz's tylecodon needs repotting

Repotting on a calendar is less reliable than reading the plant. For buchholz's tylecodon, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot buchholz's tylecodon

Every 2–3 years, into bone-dry mix. Buchholz's Tylecodon's growth habit — compact, irregularly branched succulent shrublet with a swollen, photosynthetic stem; very slow-growing — sets the pace.

What size pot to step buchholz's tylecodon up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Buchholz's Tylecodon stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot buchholz's tylecodon

Spring or summer, while buchholz's tylecodon is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting buchholz's tylecodon

Repot dry. Do not water buchholz's tylecodon for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty very gritty, fast-draining succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set buchholz's tylecodon at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep buchholz's tylecodon completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for buchholz's tylecodon

Buchholz's Tylecodon wants very gritty, fast-draining succulent mix. Use a 60:40 blend of coarse horticultural grit or pumice with cactus compost. The Namibian coastal desert origin means extremely well-drained, rocky substrate. A terracotta pot is strongly advised to allow moisture to escape through the walls. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
