Slender Psychotria Plant Care

Slender Psychotria (Psychotria tenuifolia) belongs to the Rubiaceae family within the Psychotria genus. Slender Psychotria is native to southern Florida, South America and the Caribbean. Slender Psychotria is also known as Fine-leaved Wild Coffee.

Slender Psychotria displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Slender Psychotria produces small clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Slender Psychotria every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Slender Psychotria thrives in bright indirect light. Avoid placing Slender Psychotria in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Psychotria tenuifolia tolerates temperatures of 65–80°F. Slender Psychotria prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic matter content. Good drainage is essential for Slender Psychotria to prevent waterlogging, which leads to root rot and fungal issues.

Feed Slender Psychotria every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and rich, well-draining soil with high organic matter content. Avoid low spots where water collects after rain.

Slender Psychotria is suited to USDA Zone 9b – 11b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Slender Psychotria can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Slender Psychotria while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Slender Psychotria is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Slender Psychotria can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to psychotria abdita plant care, which shares the same genus.

Slender Psychotria is susceptible to aphids, spider mites, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Slender Psychotria grows outdoors in USDA Zone 9b – 11b. It survives winters down to planting zone 9b. Slender Psychotria is native to southern Florida, South America and the Caribbean. In cooler regions, grow Slender Psychotria as a houseplant or bring it indoors before the first frost.
