🌱 Polyscias

Use a fertile, well-drained, moisture-retentive mix (e.g., potting soil with perlite for aeration plus peat/coconut fiber for water-holding). Add a small proportion of bark and/or coarse sand to prevent waterlogging. Grow in a pot with drainage holes; avoid heavy, compacted media.

Seed is uncommon in cultivation; when available, sow fresh seed warm indoors (about 24–28°C) in a sterile, free-draining medium, barely covering the seed and keeping evenly moist with high humidity and bright filtered light. More reliably, propagate by stem cuttings taken in spring–summer: use a well-drained propagating mix, bottom heat, and high humidity; pot up once rooted and harden to normal indoor conditions.

Feed during active growth (spring–summer) with a balanced liquid fertilizer at half strength every 2–4 weeks, or a light application of slow-release granular fertilizer. Reduce or stop feeding in winter. Flush the pot periodically to limit salt buildup and support micronutrients (especially iron/magnesium) if foliage pales.

In containers, apply a thin top-dressing of fine bark/wood chips to reduce surface drying and moderate root-zone temperature; keep mulch away from the stem to reduce rot. Outdoors in warm climates, mulch lightly during hot/dry periods only.

Stake young or top-heavy plants to keep the main stem upright, especially after pruning or repotting. Use a thin cane and soft ties; avoid constricting the stem and adjust ties as the plant thickens.

Traditional use commonly involves a leaf infusion/decoction: rinse fresh leaves, then steep in hot water or gently simmer for a short time and strain. Because Polyscias is a genus with many ornamental species, use only correctly identified edible/medicinal species and avoid high doses.

Prune in spring or early summer to control size and encourage branching; pinch shoot tips for a denser canopy. Remove weak or leggy growth and any dead stems; avoid cutting back too hard at once and keep cuts above a node.
