Care at a glance

Light

Trailing Elephant Bush is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Best in bright indirect light or 2–4 hours of gentle morning direct sun. An east- or west-facing window suits it well indoors. Tolerates some direct sun but prolonged harsh afternoon sun may cause leaf yellowing or reddening stress at the tips. Grows more vigorously and develops richer coloration with brighter light. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water trailing elephant bush every 7–10 days in summer; every 2–3 weeks in winter. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. More water-tolerant than most succulents due to its smaller, thinner leaves. Water when the top 2–3 cm of soil feels dry. Avoid letting the pot sit in standing water. Overwatering still causes root rot — ensure the pot always has drainage holes and the soil dries between waterings.

Soil and pot

Trailing Elephant Bush grows best in 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. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Trailing Elephant Bush sits happiest at around 30–50% humidity and 10–35°C (50–95°F). More tolerant of moderate humidity than most succulents, suiting average indoor environments well. Avoid very high humidity combined with poor air circulation, which can promote fungal issues. Does well in bright kitchens or living rooms. If you keep the room above 10–35°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed trailing elephant bush sparingly. Feed monthly during spring and summer with a balanced liquid fertiliser at half strength. Withhold fertiliser in autumn and winter. Avoid high-nitrogen feeds, which produce soft, weak stems. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on trailing elephant bush in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Leaf yellowing and dropCommonly 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.
  • Leggy trailing stemsLow light causes elongated, widely spaced stems. Increase light levels and prune back leggy growth to encourage a denser, more compact trailing habit. Pruned cuttings can be rooted easily.
  • Spider mites in dry conditionsFine webbing and stippled leaves indicate spider mites, which thrive in hot, dry indoor air. Increase humidity slightly, wipe leaves with a damp cloth, and treat with insecticidal soap or neem oil spray applied weekly until resolved.

Propagation

Very easily propagated from stem cuttings 8–12 cm long. Allow the cut end to callous for 1–2 days (shorter than most succulents due to thinner stems), then place in moist succulent mix. Roots form quickly in 2–3 weeks. Can also be rooted in water before transplanting. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Trailing Elephant Bush is pet-safe. Portulacaria afra is listed as non-toxic to cats and dogs by the ASPCA, making it a safe choice for pet-friendly homes. Ingestion of large quantities may cause mild gastrointestinal upset due to the plant's natural acidity, but it is not considered poisonous. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Trailing Elephant Bush care — frequently asked questions

What is the common name for Portulacaria afra 'Prostrata'?

Portulacaria afra 'Prostrata' is most commonly called Trailing Elephant Bush, but it is also known as Trailing Elephant Bush, Prostrate Elephant Bush, Dwarf Jade Trailing. The names refer to the same species, so care instructions for Trailing Elephant Bush apply identically to anything sold as Prostrate Elephant Bush.

How much light does trailing elephant bush need?

Trailing Elephant Bush grows best in bright indirect light (just back from a sunny window). Best in bright indirect light or 2–4 hours of gentle morning direct sun. An east- or west-facing window suits it well indoors. Tolerates some direct sun but prolonged harsh afternoon sun may cause leaf yellowing or reddening stress at the tips. Grows more vigorously and develops richer coloration with brighter light.

How often should I water trailing elephant bush?

Water trailing elephant bush every 7–10 days in summer; every 2–3 weeks in winter. More water-tolerant than most succulents due to its smaller, thinner leaves. Water when the top 2–3 cm of soil feels dry. Avoid letting the pot sit in standing water. Overwatering still causes root rot — ensure the pot always has drainage holes and the soil dries between waterings. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is trailing elephant bush toxic to cats and dogs?

Trailing Elephant Bush is pet-safe. Portulacaria afra is listed as non-toxic to cats and dogs by the ASPCA, making it a safe choice for pet-friendly homes. Ingestion of large quantities may cause mild gastrointestinal upset due to the plant's natural acidity, but it is not considered poisonous.

What USDA hardiness zone does trailing elephant bush grow in?

Trailing Elephant Bush is rated for USDA zone 9b–11 and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
