What Soil Mix Works Best for a Tropical Mat-rush?

Well-draining sandy soil with added organic matter. Good drainage is essential for Tropical Mat-rush to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Tropical Mat-rush?

Feed Tropical Mat-rush every 8 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 Tropical Mat-rush?

Choose a spot with full sun to part shade and well-draining sandy soil with added organic matter. Avoid low spots where water collects after rain.

Tropical Mat-rush 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 Tropical Mat-rush?

Tropical Mat-rush 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.

How Do You Prune a Tropical Mat-rush?

Prune Tropical Mat-rush 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.

How Do You Care for a Tropical Mat-rush in Winter?

Tropical Mat-rush 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.

How Do You Propagate a Tropical Mat-rush?

Tropical Mat-rush can be propagated through division, seeds. Similar propagation techniques also apply to mat rush plant care, which shares the same genus.
