Water a young or newly planted Small Leaved Blister Bush every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Small Leaved Blister Bush thrives in bright indirect light. Avoid placing Small Leaved Blister Bush in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Excoecaria parvifolia tolerates temperatures of 65–80°F. Small Leaved Blister Bush prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining soil mix with added perlite for improved drainage. Good drainage is essential for Small Leaved Blister Bush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Small Leaved Blister Bush every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 bright indirect light and well-draining soil mix with added perlite for improved drainage. Avoid low spots where water collects after rain.

Small Leaved Blister Bush is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Small Leaved Blister Bush can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Small Leaved Blister Bush 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 shrub in one year.

Small Leaved Blister Bush 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.
