Elephant bush

PortulacariaDidiereaceae
Also: Dwarf jade, Portulacaria
AT A GLANCE
Full sun Water: little H1babove 10 °C 60 cm–1.2 m tall · 45–90 cm wide In a pot: yes

Don't confuse it with Crassula ovata: the red flexible stems and small paired leaves are the tell. It grows and forgives faster than the jade plant, which makes it a good first succulent to practise pruning on.

Care

Light

Bright light all year, with some direct sun. It tolerates less light than most succulents but pays for it with soft growth.

Water

Water when the mix is dry through in spring and summer, and very sparingly in winter.

Soil

Free-draining gritty mix. Unlike the true jade plant it has thin, flexible red stems and small leaves, and it makes a far better subject for informal bonsai and for pinching into shape.

Pruning

The one succulent here that genuinely enjoys being cut. Pinch or prune at any point in the growing season to build a dense branching shape, and every piece removed is a cutting. Hard renovation in spring is well tolerated.

Feeding

A half-strength feed two or three times across the growing season, which is more than most succulents want — it is a faster grower and takes it without going soft, especially if it is being pruned regularly.

Propagation

Take a stem cutting of any length, strip the lower leaves, let it callus for a couple of days and push it into gritty mix. It roots so reliably that prunings are worth potting up rather than composting.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.

Common problems

Leaf drop

How to spot it. Sudden loss of leaves, often after a move or a cold night.

What to do. Usually shock or overwatering. Keep it warmer and drier and it releafs from the stems.

Soft, pale growth

How to spot it. Long internodes and floppy stems in winter.

What to do. More light and less water; pinch back in spring to restore the shape.

How to spot it. Cottony white in the leaf axils.

What to do. Alcohol on a cotton bud; isolate new plants before mixing them in.
