Cultivation methods
Psychotria amboniana K.Schum. var. velutina (E.M.A.Petit) Verdc. is native to tropical regions and can grow in various soil types, such as loam, sand, and clay. It thrives best in well-drained soil with good internal drainage. The plant prefers warm temperatures between 60 °F and 80 °F, with partial to complete shade.
Propagation can be done through stem cuttings or seedlings. For stem cuttings, choose a healthy mature stem with leaves and cut it at a 45-degree angle. Plant the cutting in soil or water, and keep it moist until roots develop. Seedlings can be started in small pots with well-draining soil, placed in a warm and humid spot.
Watering needs
Psychotria amboniana K.Schum. var. velutina (E.M.A.Petit) Verdc. requires consistent moisture but dislikes standing water. Water the plant deeply and regularly, preferably with rainwater or distilled water. Avoid using hard water or chlorinated water as it can harm the plant.
