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.

Mature size: 10–20 cm (4–8 in) tall; trailing or spreading 60–90 cm (24–36 in)

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.

How to tell trailing elephant bush needs repotting

Repotting on a calendar is less reliable than reading the plant. For trailing 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 trailing elephant bush

Every 2–3 years, into bone-dry mix. Trailing Elephant Bush's growth habit — prostrate, cascading succulent shrub with trailing reddish-brown stems and small, glossy rounded leaves; roots readily where stems touch moist soil — sets the pace.

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.

What size pot to step trailing 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. Trailing 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 trailing elephant bush

Spring or summer, while trailing 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 trailing elephant bush

Repot dry. Do not water trailing 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 well-draining succulent or cactus 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 trailing 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 trailing 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 trailing elephant bush

Trailing Elephant Bush wants well-draining succulent or cactus mix. A commercial cactus/succulent blend amended with 20–30% perlite works well. The mix should be moderately moisture-retentive compared to other succulents, but must still drain freely. Slightly acidic to neutral pH (6.0–7.0) is preferred. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting trailing elephant bush — frequently asked questions

How often should you repot trailing elephant bush?

Every 2–3 years, into bone-dry mix for trailing elephant bush. Repot trailing elephant bush every 2–3 years into a snug pot of well-draining succulent or cactus 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 trailing elephant bush need?

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

Should you water trailing elephant bush after repotting?

No — not straight away. Repot trailing 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 trailing elephant bush after repotting?

Not immediately. Wait about 3 weeks after repotting trailing 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.
