🌵 Portulacaria

Use a highly draining, aerated succulent substrate; a granular mineral mix (e.g. cactus/succulent soil amended with pumice/perlite and coarse sand/gravel) helps prevent root rot. Avoid heavy, water-holding or compacted soils, and never leave roots waterlogged; containers should be fitted with drainage holes. Containers must be fitted with drainage holes. A sandy, loamy, rocky mix is suitable, and the plant tolerates a range of soil pH, provided drainage is excellent.

Portulacaria afra is most reliable from cuttings; seed sowing is possible but less common in cultivation. From seed: - Timing: Sow in spring or early summer, when heat and light increase. - Medium: Use a sterile cactus/succulent mix with good drainage (e.g. fine compost with gravel, pumice and perlite). Use shallow pots or trays with excellent drainage. - Sowing: Spread the seeds thinly over the surface; do not bury them deeply (a very light dusting of fine sand is sufficient). Provide bright light. - Temperature: Keep warm (approx. 20-25°C). - Humidity: Moisten the medium before sowing, then keep it slightly and evenly moist (not wet). High humidity and waterlogging increase the risk of damping-off. - After germination: Increase ventilation and allow surface to dry slightly between waterings. Transplant once seedlings are large enough to be handled in a granular mix. Planting/propagation by cuttings (recommended) : - Timing: Take stem cuttings in warm, light conditions (late spring to late summer). - Preparation: Cut healthy stems, remove the lower leaves and leave the cut end to heal for several days. - Rooting: Insert the calloused end into a dry, granular cactus/succulent mix. Store in daylight (away from intense midday sun). - Watering: Wait around 5-10 days before watering lightly for the first time, then water sparingly until rooting; thereafter, water only when the mixture has dried. Outdoor planting (frost-free): - Location: Full sun with bright light; gradually acclimatize to stronger sunlight. - Soil: Very well-drained sandy/gravelly soil; avoid heavy clay or significantly improve drainage. - Spacing : Leave room for a shrub-forming succulent; space plants so that air can circulate. - Cold: Protect from frost; plant only when there is no risk of frost.

Portulacaria afra feeds very little. During the active growth period (spring to summer), apply a balanced, water-soluble fertilizer at a rate of 1/4-1/2 about once every 4 to 6 weeks, or use a low-nitrogen cactus/succulent fertilizer. Water the plant first (or fertilize with a sprinkler) to reduce root burn, and avoid fertilizing dry soil. Do not fertilize in autumn and winter, when growth slows. Avoid high-nitrogen products and frequent applications, which can lead to sluggish, weak growth; if you use a slow-release fertilizer, apply it sparingly in spring only.

Prune to shape the plant and encourage bushier growth by pinching or cutting off shoot tips. The plant tolerates severe pruning and regrows from older wood, so light plants can be severely reduced to regain a compact shape. Main pruning should take place during the active growth period (spring to early summer, or any warm, bright period for houseplants) and avoid any heavy pruning in winter or in cold, low-light conditions. Use clean, sharp tools; make cuts just above a leaf node. Allow cut surfaces to dry and maintain light watering immediately after pruning to reduce the risk of stem rot. Regular light pruning is suitable for hedges or bonsai training; remove dead or damaged stems as soon as they are visible.
