Cape Gooseberry Plant Care

Solanum retroflexum Dunal

Updated · Sources · How we source care data

Solanum retroflexum, commonly known as umsobo (isiZulu), wonderberry or sunberry, is a historic heirloom fruiting shrub. Both common names are also used for the European black nightshade in some places, particularly where the latter species has been introduced, so care must be taken to distinguish them.

What Soil Mix Works Best for a Cape Gooseberry?

Well-draining, fertile loamy soil with added compost. Good drainage is essential for Cape Gooseberry to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Cape Gooseberry?

Feed Cape Gooseberry every 4 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.

Where Should You Plant a Cape Gooseberry?

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

Cape Gooseberry is suited to USDA Zone 13a.

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.

How Far Apart Should You Plant a Cape Gooseberry?

Cape Gooseberry can spread to about 2 ft (0.6 m) and reach about 3 ft (1 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.

How Do You Prune a Cape Gooseberry?

Prune Cape Gooseberry 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.

How Do You Care for a Cape Gooseberry in Winter?

Cape Gooseberry is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cape Gooseberry can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to trailing nightshade plant care, which shares the same genus.
