It is a relatively easy plant to cultivate, and can be grown indoors or outdoors in well-draining soil with partial shade. The plant prefers a warm and humid environment and needs protection from frost.
Watering Needs
The Psychotria linearisepala E.M.A.Petit var. subobtusa Verdc. needs regular watering to keep the soil moist, but not waterlogged. It is important to avoid letting the soil dry out completely, as this can lead to leaf drop. Frequency of watering should be adjusted based on the temperature and humidity levels in the environment.
Fertilization
The Psychotria linearisepala E.M.A.Petit var. subobtusa Verdc. will benefit from regular fertilization during the growing season. A balanced fertilizer applied every two weeks will help maintain healthy growth. Take care not to over-fertilize, as this can cause damage to the roots.
Pruning
Pruning should be done in early spring, before the plant enters its active growing season. Trim back any dead or damaged branches, and prune to shape the plant as desired.
