Caucasian Stonecrop Plant Care

Caucasian Stonecrop (Phedimus spurius) belongs to the Crassulaceae family within the Phedimus genus. Caucasian Stonecrop is also known as Stonecrop.

Caucasian Stonecrop displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Caucasian Stonecrop produces small star-shaped flowers in shades of pink, white, or yellow.

Leaf size: approximately 2 inches.

Water a young or newly planted Caucasian Stonecrop 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.

Caucasian Stonecrop thrives in full sun to partial shade.

Phedimus spurius tolerates temperatures of 50–80°F. Caucasian Stonecrop prefers humidity levels of 30–60%.

Well-draining sandy soil mix with added perlite for good aeration. Good drainage is essential for Caucasian Stonecrop to prevent waterlogging, which leads to root rot and fungal issues.

Feed Caucasian Stonecrop 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 soil mix with added perlite for good aeration. Avoid low spots where water collects after rain.

Caucasian Stonecrop 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.

Caucasian Stonecrop can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Caucasian Stonecrop 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.

Caucasian Stonecrop 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.

Caucasian Stonecrop can be propagated through leaf cuttings, stem cuttings, division. Similar propagation techniques also apply to aizoon stonecrop plant care, which shares the same genus.

Caucasian Stonecrop is susceptible to mealybugs, aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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