Elephant Bush Care Guide
Portulacaria afra
Quick Answer
The most common mistake with Elephant Bush is overwatering — it stores water and handles drought far better than soggy soil. Let the soil dry out completely between waterings and when in doubt, wait another few days. Plant it in fast-draining mix (a cactus or succulent blend) and a pot with good drainage to give yourself a margin for error.

Watering

Winter
Every 21–30 days
Method: Allow soil to dry completely before watering; water thoroughly and drain; very drought tolerant once established
In summer, aim to water elephant bush approximately every 10–14 days; in winter cut back to around every 21–30 days. Rather than following a calendar, let the soil dry out completely — all the way to the bottom of the pot. Water thoroughly until water drains from the bottom, then don't water again until the soil passes the dryness check. Soft or mushy leaves signal overwatering; slight wrinkling or shrivelling means it's time to water.
Light Requirements
Bright indirect to full sun
Elephant Bush does best in a south- or west-facing windowsill where it gets at least 2–4 hours of direct sun. Without direct light, Elephant Bush stretches toward the light source, loses its compact shape, and colour or markings may fade.
Soil & Potting
Soil: Cactus/succulent mix or well-draining potting mix
Pot: Any pot with drainage; used extensively in bonsai
Temperature & Humidity
Temperature: 45–90°F (7–32°C)
Humidity: Low (under 40%)
Fertilizing
Frequency: Monthly in spring/summer at half strength; skip fall/winter
Type: Balanced or low-nitrogen succulent fertilizer
Common Problems
Leaf drop
Leaf drop: Overwatering or insufficient light. Check both. Check the roots: if they're dark, mushy, or smell off, root rot has set in. Unpot the plant, trim all affected roots with clean scissors, dust with cinnamon, and repot in fresh dry mix before resuming a cautious watering schedule.
Mushy stem
Mushy stem: Root rot from overwatering. Repot into dry soil; remove rotten roots. Check the roots: if they're dark, mushy, or smell off, root rot has set in. Unpot the plant, trim all affected roots with clean scissors, dust with cinnamon, and repot in fresh dry mix before resuming a cautious watering schedule.
Slow growth
Slow growth: Insufficient light. Move to brighter spot. Brown spots can mean cold water on leaves, direct sun damage, or the early stages of overwatering. Use room-temperature water, avoid wetting the leaves when watering, and make sure the plant isn't in direct harsh afternoon sun.
Mealybugs
Mealybugs: Check stem joints. Treat with neem oil. Check under leaves and along stems regularly, since pests establish colonies before becoming visible from above. Treat with insecticidal soap or neem oil, covering the undersides of leaves, and repeat every 5–7 days for at least three rounds.
Propagation
The easiest way to propagate Elephant Bush is by stem cuttings. Take a 4–6 inch cutting that includes at least one node (the point where a leaf attaches). Remove any leaves that would be submerged, then place it in water or directly into moist potting mix. In water, roots appear within 2–4 weeks; pot up once they reach an inch long. The thing that trips people up most: taking a cutting without a node. Without a node, the cutting stays green for weeks but will never root.
Seasonal Care Calendar
🌸 Spring
Spring is when Elephant Bush starts actively pushing new growth as day length and light intensity increase. Increase watering frequency as the plant becomes more active, begin fertilising every 2–4 weeks with a balanced liquid fertiliser, and this is the ideal window for repotting or taking cuttings.
☀️ Summer
Summer is peak growing season — Elephant Bush is working hard and using water and nutrients faster than at other times of year. Water more frequently but check the soil rather than going on a fixed schedule, since heat and higher light accelerate drying. If you move it outdoors, introduce it to conditions gradually to prevent sun scorch.
🍂 Fall
As temperatures drop and light levels decrease in fall, begin tapering off watering. Elephant Bush will naturally slow its growth rate — this is normal. Stop fertilising by late October and avoid any unnecessary repotting before winter.
❄️ Winter
Winter is near-dormancy for Elephant Bush. Water only when the soil has been completely dry for at least a week, which may mean once a month or less. Hold off on fertilising entirely until spring. Don't panic if growth stops completely — this rest is essential for the plant's long-term health.
