Juglans boliviana Plant Care

Juglans boliviana (Juglans boliviana) belongs to the Juglandaceae family within the Juglans genus.

Juglans boliviana displays a tall, deciduous tree growth habit, reaching up to 100 ft tall with a spread of approximately 50 ft. Juglans boliviana produces inconspicuous greenish flowers.

Leaf size: approximately 12 inches.

Water a young or newly planted Juglans boliviana 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.

Juglans boliviana thrives in full sun.

Juglans boliviana tolerates temperatures of 0–100°F. Juglans boliviana prefers humidity levels of 30–70%.

Rich, well-draining soil with good organic content. Good drainage is essential for Juglans boliviana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Juglans boliviana 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.

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

Choose a spot with full sun and rich, well-draining soil with good organic content. Avoid low spots where water collects after rain.

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.

Juglans boliviana can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Juglans boliviana 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.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Juglans boliviana can be propagated through seeds, grafting. Similar propagation techniques also apply to butternut plant care, which shares the same genus.

Juglans boliviana is susceptible to walnut caterpillars, walnut husk flies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
