About Cape Clubfoot

Pachypodium bispinosum · also called Cape Clubfoot, Twin-spined Thick-foot · tropical

A South African caudiciform native to the rocky scrub of the Eastern Cape, forming an impressive partially buried caudex up to 60 cm across with wiry, spiny branches bearing small leaves. Produces charming bell-shaped pink to purple flowers in spring and summer. More cold-tolerant than its Malagasy relatives. Requires bright sun, sharp drainage, and very little water in winter.

Mature size: Caudex up to 60 cm (24 in) tall and 25 cm (10 in) in diameter; overall plant (branches included) to approximately 60 cm (24 in) tall. Slow-growing.

Watch for — Yellow leaves and leaf drop: Some winter deciduousness is normal. Yellow leaves during summer growth usually indicate overwatering, compacted soil, or (less commonly) iron deficiency from overly alkaline substrate.

How to tell cape clubfoot needs repotting

Repotting on a calendar is less reliable than reading the plant. For cape clubfoot, watch for these signs:

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that cape clubfoot bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot cape clubfoot

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, cape clubfoot is lifted and divided once the clump congests and flowering drops off. Caudiciform succulent shrublet with a grossly swollen, tuberous caudex that is partially buried. Multiple thin, wiry, spiny branches emerge from the caudex apex bearing small deciduous leaves. Slower-growing than most Malagasy Pachypodium. Semi-deciduous in winter..

What size pot to step cape clubfoot up to

Pot size matters less than depth and spacing here. When you replant cape clubfoot, set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot cape clubfoot

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing cape clubfoot in full growth or flower sets it back badly.

Step-by-step: repotting cape clubfoot

Wait for dormancy. Let cape clubfoot foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh gritty, fast-draining cactus mix at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting cape clubfoot, keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for cape clubfoot

Cape Clubfoot wants gritty, fast-draining cactus mix. Use sandy cactus compost mixed with coarse grit or perlite at a ratio of roughly 50:50. Target pH of 6.0–7.0. The pot must have drainage holes. Avoid heavy, compacted, or moisture-retaining soils that increase rot risk around the caudex. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cape clubfoot — frequently asked questions

How often should you repot cape clubfoot?

Lift and divide every 3–4 years once clumps congest for cape clubfoot. Cape Clubfoot is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in gritty, fast-draining cactus mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does cape clubfoot need?

When is the best time of year to repot cape clubfoot?

Do you "repot" cape clubfoot, or lift and divide it?

You lift and divide it. Cape Clubfoot grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise cape clubfoot after repotting?

Hold off feeding cape clubfoot until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
