About African Kedrostis

Kedrostis africana · also called African Kedrostis, Baboon's Cucumber · houseplant

A dramatic South African caudiciform (Cucurbitaceae) producing a woody underground caudex up to 50 cm across from which annual twining vines emerge each season. Grow in full light with some protection from harsh afternoon sun, water moderately in summer and keep nearly dry in winter. Excellent for hanging baskets or a trellis.

Mature size: Vines 0.5–1 m per season; caudex up to 50 cm across at maturity

Indoor size vs how big it gets in the wild

African Kedrostis does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect vines 0.5–1 m per season. In the ground with no restriction it is a completely different plant — caudex up to 50 cm across at maturity — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

African Kedrostis is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced liquid fertiliser at half strength once a month during the active growing season (spring to late summer). do not feed during winter dormancy.

Want this turned into the right next pot at the right moment? The pot size calculator and the african kedrostis repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast african kedrostis grows.

How to keep african kedrostis smaller

You are not stuck with the maximum size. For african kedrostis specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — african kedrostis takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of african kedrostis should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow african kedrostis bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for african kedrostis the accelerators are:

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The african kedrostis light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When african kedrostis outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for african kedrostis:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the african kedrostis repotting guide. If you want more of this plant instead of a bigger one, the african kedrostis propagation guide turns prunings into new plants.

African Kedrostis size — frequently asked questions

How big does african kedrostis get?

African Kedrostis reaches vines 0.5–1 m per season when grown indoors, and far larger where it grows unrestricted (caudex up to 50 cm across at maturity). Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Is african kedrostis slow or fast growing?

African Kedrostis is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. African Kedrostis does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims.

How long does african kedrostis take to reach full size?

Roughly three to six years to reach mature indoor size, gaining a steady amount each growing season. Light, pot size and feeding move that timeline more than anything else.

How do I keep african kedrostis smaller?

Trim the longest vines back to the length you want — african kedrostis takes hard cutting well and bushes out from the cut.
