Small-flowered Mat-rush Plant Care

Small-flowered Mat-rush (Lomandra micrantha) belongs to the Asparagaceae family within the Lomandra genus.

Small-flowered Mat-rush displays a grass-like clumping growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Small-flowered Mat-rush produces small yellow blooms on tall spikes.

Leaf size: approximately 12 inches.

Water a young or newly planted Small-flowered Mat-rush every 7–14 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.

Small-flowered Mat-rush thrives in full sun to part shade.

Lomandra micrantha tolerates temperatures of 50–85°F. Small-flowered Mat-rush prefers humidity levels of 40–70%.

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

Feed Small-flowered 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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.

Small-flowered 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.

Small-flowered 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.

Prune Small-flowered 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.

Small-flowered 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.

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