What Soil Mix Works Best for a Trailing Deerweed?
Well-draining sandy soil with good organic content. Good drainage is essential for Trailing Deerweed to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Trailing Deerweed?
Feed Trailing Deerweed 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 Trailing Deerweed?
Choose a spot with full sun to partial shade and well-draining sandy soil with good organic content. Avoid low spots where water collects after rain.
Trailing Deerweed 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 Trailing Deerweed?
Trailing Deerweed can spread to about 3 ft (0.9 m) and reach about 2 ft (0 m) tall. Space plants about 3 ft (0.9 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 Trailing Deerweed?
Prune Trailing Deerweed 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.
