Everything it needs
9 essentials at a glance
Watering
Portulacaria afra, commonly known as Elephant Bush, prefers to dry out between waterings.
Water every 2-3 weeks during the growing season (spring and summer), allowing the top 1-2 inches of soil to dry out completely before rewatering. In fall and winter, reduce watering to once a month. Signs of overwatering include yellowing leaves and mushy stems, while under-watering may cause leaf drop and shriveling.
Light
This plant thrives in bright, indirect light but can tolerate full sun.
Ideally, it should receive at least 6 hours of light daily. If grown indoors, place it near a south or west-facing window. It can handle some shade but may become leggy if light is insufficient.
Soil
Portulacaria afra prefers well-draining soil with a pH of 6.0 to 7.0.
A cactus or succulent potting mix is ideal, or you can create your own by mixing regular potting soil with sand and perlite to improve drainage.
Humidity
Elephant Bush prefers low to moderate humidity levels, ideally around 30-50%.
To increase humidity, you can mist the plant occasionally or place it on a pebble tray with water. Signs of low humidity stress include leaf curling and browning tips.
Temperature
This succulent thrives in temperatures between 65-80°F (18-27°C) and is hardy in USDA zones 10-11.
It can tolerate brief periods of cooler temperatures down to 50°F (10°C) but should be protected from frost and extreme heat.
Fertilizing
Use a balanced, diluted liquid fertilizer with an NPK ratio of 10-10-10 or a cactus fertilizer every 4-6 weeks during the growing season.
Reduce or stop fertilizing in fall and winter. Signs of nutrient deficiency include pale leaves and stunted growth.
Pruning
Prune in early spring to maintain shape and encourage bushier growth.
Use clean, sharp scissors or pruning shears to remove any leggy stems or dead leaves. Deadheading is not necessary for this plant.
Repotting
Repot every 2-3 years or when the plant outgrows its pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot one size larger with good drainage. Carefully remove the plant from its pot, trim any damaged roots, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or leaf cuttings.
For stem cuttings, take a healthy stem, let it dry for a few days to callous, then plant it in well-draining soil. For leaf cuttings, allow the leaves to callous before placing them on the soil surface. Best timing for propagation is in spring or early summer.

Root rot
Why it happens
Overwatering and poor drainage.
How to fix it

Care through the year
Spring
In spring, resume regular watering and fertilizing as the plant begins its active growth phase. Prune any leggy growth to encourage bushiness.
Summer
During summer, ensure the plant receives plenty of sunlight and monitor for signs of dehydration, watering every 2-3 weeks as needed.
Fall
In fall, gradually reduce watering frequency as the plant enters dormancy. Stop fertilizing and prepare for cooler temperatures.
Winter
In winter, water sparingly, about once a month, and keep the plant in a warm location away from drafts to prevent cold stress.
