How to grow

Cultivation

Grow in a fast-draining, peat-free, loam-based compost with added extra organic matter. Position in bright, indirect light with shade from hot sun. In growth, water moderately and apply a balanced liquid feed monthly; keep just moist in winter. Hoyas resent repotting and can stay in the same pot for many years. See hoya cultivation

Propagation

Propagate by layering in spring or summer; root semi-ripe cuttings with bottom heat in late summer
