Petrosavia sakuraii Plant Care

Petrosavia sakuraii (Petrosavia sakuraii) belongs to the Petrosaviaceae family within the Petrosavia genus. Petrosavia sakuraii is native to dark montane rainforests.

Petrosavia sakuraii displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Petrosavia sakuraii produces small inconspicuous flowers.

Leaf size: approximately 8 inches.

Water a young or newly planted Petrosavia sakuraii every 7–10 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.

Petrosavia sakuraii thrives in bright indirect light. Avoid placing Petrosavia sakuraii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Petrosavia sakuraii tolerates temperatures of 65–80°F. Petrosavia sakuraii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil mix with high organic content. Good drainage is essential for Petrosavia sakuraii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Petrosavia sakuraii 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 sandy soil mix with high organic content. Avoid low spots where water collects after rain.

Petrosavia sakuraii 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.

Petrosavia sakuraii can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Petrosavia sakuraii 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.

Petrosavia sakuraii 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.

Petrosavia sakuraii can be propagated through division of rhizomes, seeds.

Petrosavia sakuraii grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Petrosavia sakuraii is native to dark montane rainforests. In cooler regions, grow Petrosavia sakuraii as a houseplant or bring it indoors before the first frost.
