How to Grow and Care for Portulacaria Afra
Portulacaria afra can be grown outdoors or indoors. As an outdoor succulent, Portulacaria afra is a perfect addition to a miniature garden or rock garden.
Elephant Bush is not a cold-hardy succulent. If the temperature in your region drops below 30° F or 1.7° C, it would be best if the succulent is planted in a pot that can be brought indoors.
You can also use Portulacaria afra as a hanging plant and allow its long stems to extend downward. It will be a wonderful ornament for your patio.
Portulacaria afra responds well to partial or full sunlight. If grown outdoors, plant Portulacaria afra in a location that gets 6 hours of sunlight.
If Elephant Bush is grown indoors, place the pot in an area in a room with a warm temperature. Position the plant near a window that gets indirect sunlight.
Portulacaria afra is a succulent that is highly resistant to drought. You don’t have to give it plenty of water to thrive. Elephant Bush can adapt to both dry and hot conditions.
As a rule, Portulacaria afra will require more water during the summer months. Like other succulents, give the plant water only when the soil is free of moisture.
In the winter months, reduce Elephant Bush’s watering schedule because the soil stays moist much longer.
To keep your Portulacaria afra succulent healthy, feed the soil with fertilizer that has been diluted with water to reduce its strength by 50%. Fertilizer should only be given during the early spring or late winter.
3. Pot and Soil
Plant Portulacaria afra in a pot that has excellent draining properties. The succulent cannot stay in moist soil for a long period. Otherwise, its roots may rot and infect the entire plant.
Use a rock or a stake to keep Elephant Bush stable and upright because its thick stems and succulent leaves add more weight to its top. The stake can keep the plant upright and stable until such time that it becomes well-rooted in the soil.
The best soil to use would be well-draining potting soil, cactus soil or sandy soil which are all well-draining and allow proper air circulation around Portulacaria afra’s roots.
It is recommended to repot Portulacaria afra every 2 years to ensure that the succulent is getting sufficient nutrients from the soil.
How to Propagate Portulacaria Afra
Keeping Portulacaria afra indoors has another benefit: it is reported that Elephant Bush can absorb dangerous carbon monoxide particles in the air. The succulent is sometimes described as a “carbon sponge”.
If you want to keep the air inside your house, outside your patio and garden clean, grow more Portulacaria afra.
The good news is, it is easy to propagate the Portulacaria afra by using the stem cuttings method.
Step 1: Cut a stem using a sterilized and sharpened knife or garden shears.
Step 2: Place the stem under a shaded area and let it dry. The process of naturally drying the stem will help it develop calluses that are necessary for propagation. It will take several days for the stem to have calluses.
Step 3: Once the calluses have developed on the stem, place it in a pot of well-draining soil.
Step 4: Keep the plant out of direct sunlight while it is setting its roots. This process will take 4 to 6 weeks.
Step 5: Give the plant water whenever the soil feels dry to the touch.
