Psychotria carronis Plant Care

Psychotria carronis (Psychotria carronis) belongs to the Rubiaceae family within the Psychotria genus.

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

Leaf size: approximately 6 inches.

Water a young or newly planted Psychotria carronis 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.

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

Psychotria carronis tolerates temperatures of 65–80°F. Psychotria carronis 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 Psychotria carronis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Psychotria carronis 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.

Psychotria carronis is suited to USDA Zone 13b.

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.

Psychotria carronis 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 Psychotria carronis 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.

Psychotria carronis is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

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

Psychotria carronis 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.

Psychotria carronis grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Psychotria carronis as a houseplant or bring it indoors before the first frost.
