About Variegated Elephant Bush

Portulacaria afra 'Variegata' · also called Rainbow Bush, Variegated Spekboom · houseplant

Variegated elephant bush is a shrubby South African succulent with reddish stems and small rounded leaves splashed cream and green, often blushing pink at the edges in sun. Slower and more pendulous than the green spekboom, it is a favourite for bonsai and hanging pots. Foliage is widely regarded as non-toxic and even edible.

Mature size: Indoors and in pots typically 30-90 cm, eventually more if unpruned; markedly slower and smaller than the plain-green spekboom, which makes it well suited to compact displays and bonsai.

Watch for — Rot from overwatering: Soggy soil rots the stems and roots, and the variegated form is more sensitive than the green. Let the mix dry fully and use sharply draining compost.

How to tell variegated elephant bush needs repotting

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

Every 2–3 years, into bone-dry mix. Variegated Elephant Bush's growth habit — a slow-growing, woody-stemmed succulent shrub with a sprawling-to-pendulous habit; reddish branches carry pairs of small variegated leaves and the plant readily takes to shaping for bonsai or trailing in pots. — sets the pace. Variegated elephant bush is a shrubby South African succulent with reddish stems and small rounded leaves splashed cream and green, often blushing pink at the edges in sun. Slower and more pendulous than the green spekboom, it is a favourite for bonsai and hanging pots. Foliage is widely regarded as non-toxic and even edible.

What size pot to step variegated 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. Variegated 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 variegated elephant bush

Spring or summer, while variegated 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 variegated elephant bush

Repot dry. Do not water variegated 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 gritty, fast-draining cactus or 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 variegated 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 variegated 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 variegated elephant bush

Variegated Elephant Bush wants gritty, fast-draining cactus or succulent mix. A cactus compost with added perlite, pumice or coarse grit gives the drainage it needs. Use a pot with drainage holes. For bonsai it grows in shallow, free-draining substrate. Avoid heavy, moisture-retentive mixes that keep the roots wet. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting variegated elephant bush — frequently asked questions

How often should you repot variegated elephant bush?

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

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

Should you water variegated elephant bush after repotting?

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

Not immediately. Wait about 3 weeks after repotting variegated 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.
