Siberian Pea Shrub Plant Care

Siberian Pea Shrub (Caragana acanthophylla) belongs to the Fabaceae family within the Caragana genus. Siberian Pea Shrub is native to a number of countries across Asia including China, India, Kazakhstan, Kyrgyzstan, Nepal, Pakistan and Tajikistan. Siberian Pea Shrub is also known as Pea Shrub.

Siberian Pea Shrub displays a deciduous shrub, upright growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Siberian Pea Shrub produces yellow pea-like flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Siberian Pea Shrub 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.

Siberian Pea Shrub thrives in full sun to partial shade.

Caragana acanthophylla tolerates temperatures of 0–100°F. Siberian Pea Shrub prefers humidity levels of 30–70%.

Well-draining sandy loam with good fertility. Good drainage is essential for Siberian Pea Shrub to prevent waterlogging, which leads to root rot and fungal issues.

Feed Siberian Pea Shrub every 8 months 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 full sun to partial shade and well-draining sandy loam with good fertility. 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.

Siberian Pea Shrub can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Siberian Pea Shrub 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.

Siberian Pea Shrub can be propagated through seeds, hardwood cuttings. Similar propagation techniques also apply to siberian pea shrub plant care, which shares the same genus.

Siberian Pea Shrub is susceptible to 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.
