Cratoxylum maingayi Plant Care

Cratoxylum maingayi (Cratoxylum maingayi) belongs to the Hypericaceae family within the Cratoxylum genus.

Cratoxylum maingayi displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Cratoxylum maingayi produces small, white, fragrant flowers in clusters.

Leaf size: approximately 5 inches.

Water a young or newly planted Cratoxylum maingayi 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.

Cratoxylum maingayi thrives in partial shade to full sun.

Cratoxylum maingayi tolerates temperatures of 60–85°F. Cratoxylum maingayi prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with high organic matter content. Good drainage is essential for Cratoxylum maingayi to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cratoxylum maingayi every 6 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.

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

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

Cratoxylum maingayi is suited to USDA Zone 13a.

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.

Cratoxylum maingayi can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cratoxylum maingayi 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.

Cratoxylum maingayi 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.

Cratoxylum maingayi can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cratoxylum arborescens plant care, which shares the same genus.

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

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