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.
Growth habit: Prostrate, cascading succulent shrub with trailing reddish-brown stems and small, glossy rounded leaves; roots readily where stems touch moist soil
What fertiliser trailing elephant bush actually wants — and why
Trailing Elephant Bush is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for trailing elephant bush: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed trailing elephant bush, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For trailing elephant bush:
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. Treat that as monthly between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when trailing elephant bush is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for trailing elephant bush
Half strength is the safe default for trailing elephant bush — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water trailing elephant bush first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the trailing elephant bush watering schedule.
Signs you are over-feeding trailing elephant bush
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for trailing elephant bush:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding trailing elephant bush
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full trailing elephant bush care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of trailing elephant bush with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for trailing elephant bush
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding trailing elephant bush look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding trailing elephant bush year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of trailing elephant bush?
Flush the pot of trailing elephant bush with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
