Corynocarpus dissimilis Plant Care

Corynocarpus dissimilis (Corynocarpus dissimilis) belongs to the Corynocarpaceae family within the Corynocarpus genus. Corynocarpus dissimilis is native to dense humid and dry forests, reaching 1,200 m (3,900 ft) above sea level at maximum elevation.

Corynocarpus dissimilis displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Corynocarpus dissimilis produces small inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Corynocarpus dissimilis 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.

Corynocarpus dissimilis thrives in full sun to partial shade.

Corynocarpus dissimilis tolerates temperatures of 50–85°F. Corynocarpus dissimilis prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Corynocarpus dissimilis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Corynocarpus dissimilis 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Corynocarpus dissimilis is suited to USDA Zone 12a.

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.

Corynocarpus dissimilis 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 Corynocarpus dissimilis 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.

Corynocarpus dissimilis is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Corynocarpus dissimilis can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to karaka plant care, which shares the same genus.

Corynocarpus dissimilis is susceptible to 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.

Corynocarpus dissimilis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Corynocarpus dissimilis is native to dense humid and dry forests, reaching 1,200 m (3,900 ft) above sea level at maximum elevation. In cooler regions, grow Corynocarpus dissimilis as a houseplant or bring it indoors before the first frost.
