Plant Limosella australis in partial to full shade (USDA zones 12a) and water a young shrub every 3–5 days until it is established. It tolerates temperatures of 50–75°F (10–24°C). Fertilize it every 6 months during the growing season.
Where Is the Limosella australis Native To?
What Is the Limosella australis?
Limosella australis (Limosella australis) belongs to the Plantaginaceae family within the Limosella genus. Limosella australis is native to the United States and Canada.
Limosella australis displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Limosella australis produces small, inconspicuous flowers in clusters.
Leaf size: approximately 1 inches.
How Often Should You Water a Limosella australis?
Water a young or newly planted Limosella australis 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.

Until established; then in dry spells
What Light Does the Limosella australis Need?
Limosella australis thrives in partial to full shade. The optimal light range is 50–500 lux. Avoid placing Limosella australis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

What Soil Mix Works Best for a Limosella australis?
Moist, well-draining soil with high organic content. Good drainage is essential for Limosella australis to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Limosella australis?
Feed Limosella australis 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 Limosella australis?
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.
Limosella australis 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 Limosella australis?
Limosella australis 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 Limosella australis?
Prune Limosella australis 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 Limosella australis in Winter?
Limosella australis 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 Limosella australis?
Limosella australis can be propagated through seeds, division of clumps. Similar propagation techniques also apply to weak-stemmed mudwort plant care, which shares the same genus.
Is the Limosella australis Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Limosella australis, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
