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.
Growth habit: Compact, irregularly branched succulent shrublet with a swollen, photosynthetic stem; very slow-growing
Watch for — Sunburn on the stem: Unlike many succulents, T. buchholzianus naturally grows in partially shaded rock crevices. Sudden exposure to intense afternoon sun can scorch the smooth photosynthetic bark. Acclimate slowly to any change in light levels.
What fertiliser buchholz's tylecodon actually wants — and why
Buchholz's Tylecodon is a light-feeding succulent — a gentle, low-nitrogen feed a few times in growth keeps it plump without forcing the weak, stretched growth over-feeding causes.
A cactus and succulent formula or a diluted balanced feed with modest, even numbers. Avoid high-nitrogen plant foods — they make a succulent etiolate and grow soft, fracture-prone tissue.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for buchholz's tylecodon: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed buchholz's tylecodon, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For buchholz's tylecodon:
Feed with a dilute (quarter-strength) low-nitrogen liquid cactus fertiliser once a month during the active growing season (autumn to early spring) only. Do not fertilise during summer dormancy. Keep that to once a month between spring through early autumn (roughly March to September) and stop entirely once growth slows for winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when buchholz's tylecodon is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for buchholz's tylecodon
Quarter to half strength at most for buchholz's tylecodon. Succulents take up very little, and a strong dose burns the fine roots before the plant can use it.
Feeding always goes onto already-damp soil, never dry roots — water buchholz's tylecodon first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the buchholz's tylecodon watering schedule.
Signs you are over-feeding buchholz's tylecodon
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for buchholz's tylecodon:
- Stretched, leggy, pale growth with widely spaced leaves.
- A white salt crust on the soil or around the pot rim.
- Brown, crisped leaf tips and edges.
- Soft, mushy tissue at the base — over-feeding plus damp soil rots it.
Signs you are under-feeding buchholz's tylecodon
- Uncommon — succulents tolerate lean conditions well.
- Very slow growth and dull, faded colour over a long period.
- Older leaves shed faster than new ones replace them in a tired old mix.

Flushing and leaching the salts
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of buchholz's tylecodon until it drains clear, and refresh the gritty mix every 2-3 years.
Organic vs synthetic feeds for buchholz's tylecodon
Organic options
A heavily diluted seaweed or worm-casting feed once or twice in summer. UK: a drop of Westland seaweed feed; US: quarter-strength Espoma Cactus! or Dr. Earth liquid. Fresh free-draining mix matters more than any feed.
Synthetic / liquid feeds
A dedicated cactus/succulent liquid at quarter to half strength — UK: Baby Bio Cacti & Succulent Drip Feeders or Westland; US: Miracle-Gro Succulent Plant Food or Schultz Cactus Plus.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding buchholz's tylecodon look like?

Soft, mushy tissue at the base — over-feeding plus damp soil rots it. Feeding buchholz's tylecodon like a leafy houseplant is the classic error — it produces a flush of pale, stretched, floppy growth that never firms up and is prone to rot at the base.
Should I flush the soil of buchholz's tylecodon?
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of buchholz's tylecodon until it drains clear, and refresh the gritty mix every 2-3 years.
