Weak-stemmed Mudwort Plant Care

Weak-stemmed Mudwort (Limosella acaulis) belongs to the Plantaginaceae family within the Limosella genus. Weak-stemmed Mudwort is native to western North America from the Pacific Northwest to northern Mexico. Weak-stemmed Mudwort is also known as Mudwort.

Weak-stemmed Mudwort displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Weak-stemmed Mudwort produces small, inconspicuous flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted Weak-stemmed Mudwort every 3–5 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.

Weak-stemmed Mudwort thrives in partial to full shade. The optimal light range is 50–500 lux. Avoid placing Weak-stemmed Mudwort in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Limosella acaulis tolerates temperatures of 50–75°F. Weak-stemmed Mudwort prefers humidity levels of 40–70%.

Moist, well-draining soil with high organic content. Good drainage is essential for Weak-stemmed Mudwort to prevent waterlogging, which leads to root rot and fungal issues.

Feed Weak-stemmed Mudwort 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.

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

Choose a spot with partial to full shade and moist, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Weak-stemmed Mudwort 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.

Weak-stemmed Mudwort 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.

Prune Weak-stemmed Mudwort 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.

Weak-stemmed Mudwort 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.

Weak-stemmed Mudwort can be propagated through seeds, division of clumps. Similar propagation techniques also apply to waterwort plant care, which shares the same genus.

Weak-stemmed Mudwort grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Weak-stemmed Mudwort is native to western North America from the Pacific Northwest to northern Mexico. In cooler regions, grow Weak-stemmed Mudwort as a houseplant or bring it indoors before the first frost.
