Red Stem Portulacaria afra
Start in spring for late-spring to summer finish. Sunbelt states can grow year round. PPP: 1 liner per 2" pot, 3 liners per gallon.
Most varieties branch on their own. Pinch if plants start to stretch before branching. Prune larger plants when they start to stretch.
Watch for aphids and spider mites in summer. Snails and slugs can be a problem. Overwatering and cold, damp conditions cause root rot. Succulents are very sensitive to pesticide burn. Always conduct a small-scale test application first. Leaf spots and bruising may occur after handling; plants will outgrow symptoms.
Start in small pots and repot if desired. Small clay pots are popular with consumers. Zone 9-11. Once established, most succulents are frost tolerant to 25F w/o damage, or 18F with slight damage. Pick off blackened leaves if frost damage occurs. The fleshier the plant, the less frost tolerant it is. Moderate grower. Great in containers and in the ground.
