Sojak's lady's mantle Plant Care

Sojak's lady's mantle (Alchemilla sojakii) belongs to the Rosaceae family within the Alchemilla genus. Sojak's lady's mantle is native to South Korea. Sojak's lady's mantle is also known as Korean lady's mantle.

Sojak's lady's mantle displays a low rosette, clumping growth habit, reaching up to 1 ft tall with a spread of approximately 2 ft. Sojak's lady's mantle produces small, yellow-green flowers in dense clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Sojak's lady's mantle every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Sojak's lady's mantle thrives in partial shade to full shade. Avoid placing Sojak's lady's mantle in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Alchemilla sojakii tolerates temperatures of 50–75°F. Sojak's lady's mantle prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Moist, well-draining soil with high organic matter content. Good drainage is essential for Sojak's lady's mantle to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sojak's lady's mantle every month during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 shade to full shade and moist, well-draining soil with high organic matter content. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Sojak's lady's mantle can spread to about 2 ft (0.6 m) and reach about 1 ft (0 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 Sojak's lady's mantle 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 tree in one year.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Sojak's lady's mantle can be propagated through division, seeds. Similar propagation techniques also apply to alpine lady's mantle plant care, which shares the same genus.

Sojak's lady's mantle is susceptible to aphids, spider mites, leaf miners. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
