Borya sphaerocephala Plant Care

Borya sphaerocephala (Borya sphaerocephala) belongs to the Boryaceae family within the Borya genus. Borya sphaerocephala is native to southwest Australia.

Borya sphaerocephala displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1 ft. Borya sphaerocephala produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Borya sphaerocephala 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.

Borya sphaerocephala thrives in full sun to partial shade.

Borya sphaerocephala tolerates temperatures of 60–80°F. Borya sphaerocephala prefers humidity levels of 40–70%.

Sandy, well-draining soil mix with added gravel for improved drainage. Good drainage is essential for Borya sphaerocephala to prevent waterlogging, which leads to root rot and fungal issues.

Feed Borya sphaerocephala 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 full sun to partial shade and sandy, well-draining soil mix with added gravel for improved drainage. Avoid low spots where water collects after rain.

Borya sphaerocephala is suited to USDA Zone 13a.

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.

Borya sphaerocephala can spread to about 1 ft (0.3 m) and reach about 2 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Borya sphaerocephala 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.

Borya sphaerocephala 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.

Borya sphaerocephala can be propagated through offsets, seeds.

Borya sphaerocephala is susceptible to mealybugs, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Borya sphaerocephala grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Borya sphaerocephala is native to southwest Australia. In cooler regions, grow Borya sphaerocephala as a houseplant or bring it indoors before the first frost.
