How do you care for Field Madder?

Plant Field Madder in partial shade to full shade (USDA zones 13a) and water a young shrub every 7–10 days until it is established. It tolerates temperatures of 60–75°F (16–24°C). Fertilize it every 6 months during the growing season.

What Is the Field Madder?

Field Madder (Sherardia arvensis) belongs to the Rubiaceae family within the Sherardia genus.

Field Madder displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Field Madder produces small, tubular white flowers in clusters.

Leaf size: approximately 2 inches.

How Often Should You Water a Field Madder?

Water a young or newly planted Field Madder 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.

What Soil Mix Works Best for a Field Madder?

Well-draining, loamy soil with added organic matter like compost or peat moss. Good drainage is essential for Field Madder to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Field Madder?

Feed Field Madder 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 Field Madder?

Choose a spot with partial shade to full shade and well-draining, loamy soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Field Madder 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.

How Far Apart Should You Plant a Field Madder?

Field Madder can spread to about 1 ft (0.3 m) and reach about 1 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.

How Do You Prune a Field Madder?

Prune Field Madder 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 Field Madder in Winter?

Field Madder 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.

How Do You Propagate a Field Madder?

Field Madder can be propagated through seeds, division of clumps. Similar propagation techniques also apply to sherardia orientalis plant care, which shares the same genus.

Is the Field Madder Toxic to Pets and Children?
