Krynitzkia circumcissa Plant Care

Krynitzkia circumcissa (Krynitzkia circumcissa) belongs to the Boraginaceae family within the Krynitzkia genus. Krynitzkia circumcissa is native to western North America from Washington to Baja California to Colorado and.

Krynitzkia circumcissa displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Krynitzkia circumcissa produces small, tubular flowers in shades of blue, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Krynitzkia circumcissa every 7–14 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.

Krynitzkia circumcissa thrives in full sun to partial shade.

Krynitzkia circumcissa tolerates temperatures of 50–80°F. Krynitzkia circumcissa prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Krynitzkia circumcissa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Krynitzkia circumcissa 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Krynitzkia circumcissa 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.

Krynitzkia circumcissa 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 Krynitzkia circumcissa 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.

Krynitzkia circumcissa 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.
