Ground cherry Plant Care

Ground cherry (Physalis grisea) belongs to the Solanaceae family within the Physalis genus. Ground cherry is native to northeastern North America. Ground cherry is also known as husk tomato.

Ground cherry displays an upright, spreading shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Ground cherry produces small, lantern-like orange or yellow blooms.

Leaf size: approximately 4 inches.

Water a young or newly planted Ground cherry every 4–7 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.

Ground cherry thrives in full sun to partial shade.

Physalis grisea tolerates temperatures of 60–80°F. Ground cherry prefers humidity levels of 40–60%.

Well-draining, fertile soil with a slightly acidic pH. Good drainage is essential for Ground cherry to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ground cherry 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.

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, fertile soil with a slightly acidic pH. Avoid low spots where water collects after rain.

Ground cherry is suited to USDA Zone 4a – 8b.

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.

Ground cherry can spread to about 3 ft (0.9 m) and reach about 2 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Ground cherry 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.

Ground cherry is hardy down to USDA zone 4a, so once established it can stay outdoors through winter in that zone and warmer ones.

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 shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Ground cherry can be propagated through seeds, division of rhizomes. Similar propagation techniques also apply to longleaf groundcherry plant care, which shares the same genus.

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

Ground cherry grows outdoors in USDA Zone 4a – 8b. It survives winters down to planting zone 4a. Ground cherry is native to northeastern North America.
