Dioncophyllum thollonii Plant Care

Dioncophyllum thollonii (Dioncophyllum thollonii) belongs to the Dioncophyllaceae family within the Dioncophyllum genus.

Dioncophyllum thollonii displays a tall tree with spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Dioncophyllum thollonii produces small, greenish-yellow flowers in clusters.

Leaf size: approximately 8 inches.

Water a young or newly planted Dioncophyllum thollonii every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Dioncophyllum thollonii thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Dioncophyllum thollonii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Dioncophyllum thollonii tolerates temperatures of 65–80°F. Dioncophyllum thollonii prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil mix with high organic content. Good drainage is essential for Dioncophyllum thollonii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Dioncophyllum thollonii every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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.

Choose a spot with partial to full shade and well-draining, acidic soil mix with high organic content. Avoid low spots where water collects after rain.

Dioncophyllum thollonii is suited to USDA Zone 13b.

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

Dioncophyllum thollonii can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Dioncophyllum thollonii 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 tree in one year.

Dioncophyllum thollonii 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.

Dioncophyllum thollonii can be propagated through seeds, stem cuttings.

Dioncophyllum thollonii is susceptible to mealybugs, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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