Cut-leaved Self-heal Plant Care

Cut-leaved Self-heal (Prunella laciniata) belongs to the Lamiaceae family within the Prunella genus. Cut-leaved Self-heal is also known as Cutleaf Self-heal.

Cut-leaved Self-heal displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Cut-leaved Self-heal produces small spikes of purple, pink, or white flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Cut-leaved Self-heal 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.

Cut-leaved Self-heal thrives in full sun to partial shade.

Prunella laciniata tolerates temperatures of 50–80°F. Cut-leaved Self-heal prefers humidity levels of 40–70%.

Well-draining loamy soil with added organic matter like compost. Good drainage is essential for Cut-leaved Self-heal to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cut-leaved Self-heal 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.

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

Cut-leaved Self-heal 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.

Cut-leaved Self-heal 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 Cut-leaved Self-heal 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.

Cut-leaved Self-heal 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.

Cut-leaved Self-heal can be propagated through seeds, division of clumps, stem cuttings. Similar propagation techniques also apply to large flowered selfheal plant care, which shares the same genus.

Cut-leaved Self-heal is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Cut-leaved Self-heal grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Cut-leaved Self-heal as a houseplant or bring it indoors before the first frost.
