Plant Care for a Rainbow Bush & Elephant Plant

Overview

Rainbow bush and elephant bush fall under the category of Portulacaria afra. They come from South Africa and grow 4 to 6 feet tall and several feet wide. The small bushes bloom with pink flowers in the spring through fall. Both varieties need bright light to grow well. Elephant plant and rainbow bush can cope with little water, making them low-maintenance plants.

Step 3

Put the rainbow bush and elephant plant in a south- or west-facing window to ensure they get full sun.

Step 4

Feed the plants with a water-soluble fertilizer. Apply the fertilizer in April and July every year. Follow the label instructions for dosage details.

Step 5

Treat mealy bugs, if they are evident. Trim off the infected branches. Spray the rainbow bush and elephant plant with a mixture of 10 percent rubbing alcohol and 90 percent water to get rid of the pests. Reapply until signs of the infestation are gone. Another option is to use insecticidal soap. Follow the label instructions for dosage details.
