Manihot walkerae Plant Care

Manihot walkerae (Manihot walkerae) belongs to the Euphorbiaceae family within the Manihot genus. Manihot walkerae is native to North America.

Manihot walkerae displays a tall, upright shrub growth habit, reaching up to 6 ft tall with a spread of approximately 3 ft. Manihot walkerae produces small, inconspicuous flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Manihot walkerae every 7–10 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.

Manihot walkerae thrives in full sun to partial shade.

Manihot walkerae tolerates temperatures of 65–85°F. Manihot walkerae prefers humidity levels of 40–60%.

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

Feed Manihot walkerae 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 sandy loam with organic matter. Avoid low spots where water collects after rain.

Manihot walkerae 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.

Manihot walkerae can spread to about 3 ft (0.9 m) and reach about 6 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Manihot walkerae 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.

Manihot walkerae 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.

Manihot walkerae can be propagated through stem cuttings, root division.

Manihot walkerae grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Manihot walkerae is native to North America. In cooler regions, grow Manihot walkerae as a houseplant or bring it indoors before the first frost.
