About Elephant bush

Portulacaria afra · also called Elephant bush, Elephant's food · houseplant

Elephant bush (Portulacaria afra) is an easy-going South African succulent shrub with glossy, coin-sized leaves on red-brown stems, often grown as an indoor mini-tree or bonsai. Its one defining need is sharp drainage: plant it in gritty cactus compost and let the soil dry between waterings, because soggy roots rot it fast.

Mature size: Indoors typically 0.6-1.2 m as a container plant or kept smaller as bonsai; outdoors in frost-free climates it can reach 1.5-2.5 m tall over many years.

Watch for — Root rot from overwatering: By far the most common problem: soggy compost causes blackening, mushy stems and sudden collapse. Always let the mix dry out, use gritty soil and a pot with drainage holes, and water less in winter.

How to tell elephant bush needs repotting

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

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot elephant bush

Every 2–3 years, into bone-dry mix. Elephant bush's growth habit — a multi-stemmed, soft-wooded evergreen shrub with reddish-brown stems that grey with age and small, fleshy, rounded leaves arranged in opposite pairs. naturally bushy and easily shaped, it is a popular subject for bonsai and trailing pot displays, and responds well to pinching and pruning. — sets the pace.

What size pot to step elephant bush up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Elephant bush stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot elephant bush

Spring or summer, while elephant bush is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting elephant bush

Repot dry. Do not water elephant bush for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining cactus and succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set elephant bush at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep elephant bush completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for elephant bush

Elephant bush wants free-draining cactus and succulent mix. Use a proprietary cactus compost, or cut multipurpose compost roughly half-and-half with grit such as perlite, pumice or horticultural sand. The aim is fast drainage so roots never sit wet. Always pot into a container with generous drainage holes; an unglazed terracotta pot helps excess moisture evaporate. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting elephant bush — frequently asked questions

How often should you repot elephant bush?

Every 2–3 years, into bone-dry mix for elephant bush. Repot elephant bush every 2–3 years into a snug pot of free-draining cactus and succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does elephant bush need?

When is the best time of year to repot elephant bush?

Should you water elephant bush after repotting?

No — not straight away. Repot elephant bush into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise elephant bush after repotting?

Not immediately. Wait about 3 weeks after repotting elephant bush. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
