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.
Preferred mix: Cactus compost with added grit
Watch for — Root and caudex rot: The most common failure, caused by overwatering or poor drainage especially during winter dormancy. Ensure the medium dries fully between waterings in winter and use a very free-draining mix.
Why african kedrostis needs this mix
African Kedrostis is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- African Kedrostis is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons african kedrostis struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates african kedrostis's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for african kedrostis.
pH — does it matter for african kedrostis?
African Kedrostis is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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 decent bagged houseplant compost works for african kedrostis as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all african kedrostis needs — the free-draining mix does the rest.
Refresh african kedrostis's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for african kedrostis covers the timing and technique step by step.
