About Trailing Elephant Bush
Portulacaria afra 'Prostrata' · also called Trailing Elephant Bush, Prostrate Elephant Bush · houseplant
A prostrate, cascading cultivar of South Africa's elephant bush, bearing tiny rounded glossy green leaves on reddish-brown stems that gracefully trail up to 60 cm. More spreading and cascading than the upright species. Tolerates more frequent watering than most succulents due to its thinner leaves. Non-toxic to cats and dogs. Superb for hanging baskets.
Preferred mix: Well-draining succulent or cactus mix
Watch for — Leaf yellowing and drop: Commonly caused by overwatering or insufficient light. Check soil moisture before watering and move to a brighter location. If yellowing occurs from the base upward, root rot may be present — unpot and inspect the roots.
Why trailing elephant bush needs this mix
Trailing Elephant Bush is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Trailing Elephant Bush 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 trailing elephant bush 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 trailing elephant bush'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 trailing elephant bush.
pH — does it matter for trailing elephant bush?
Trailing Elephant Bush 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 trailing elephant bush 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 trailing elephant bush needs — the free-draining mix does the rest.
Refresh trailing elephant bush'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 trailing elephant bush covers the timing and technique step by step.
