What Soil Mix Works Best for a Batt's Sunray?

Well-draining sandy soil with added compost for nutrients. Good drainage is essential for Batt's Sunray to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Batt's Sunray?

Feed Batt's Sunray 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.

Where Should You Plant a Batt's Sunray?

Choose a spot with full sun to partial shade and well-draining sandy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Batt's Sunray is suited to USDA Zone 12a.

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.

How Far Apart Should You Plant a Batt's Sunray?

Batt's Sunray can spread to about 2 ft (0.5 m) and reach about 1 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.

How Do You Prune a Batt's Sunray?

Prune Batt's Sunray 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.

Batt's Sunray is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Batt's Sunray can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to chamomile sunray plant care, which shares the same genus.
