Oblongleaf Gopher-apple Plant Care

Oblongleaf Gopher-apple (Geobalanus oblongifolius) belongs to the Chrysobalanaceae family within the Geobalanus genus. Oblongleaf Gopher-apple is also known as Gopher-apple.

Oblongleaf Gopher-apple displays a tall canopy tree growth habit, reaching up to 50 ft tall with a spread of approximately 30 ft. Oblongleaf Gopher-apple produces small clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Oblongleaf Gopher-apple 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.

Oblongleaf Gopher-apple thrives in full sun to partial shade.

Geobalanus oblongifolius tolerates temperatures of 65–85°F. Oblongleaf Gopher-apple prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Oblongleaf Gopher-apple to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oblongleaf Gopher-apple 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.

Choose a spot with full sun to partial shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Oblongleaf Gopher-apple 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.

Oblongleaf Gopher-apple can spread to about 30 ft (9.1 m) and reach about 50 ft (15 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oblongleaf Gopher-apple 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.

Oblongleaf Gopher-apple 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.

Oblongleaf Gopher-apple can be propagated through seeds, stem cuttings.
