Indian Rennet Plant Care

Indian Rennet (Withania coagulans) belongs to the Solanaceae family within the Withania genus. Indian Rennet is native to Afghanistan and the Indian subcontinent. Indian Rennet is also known as Indian Cheese Maker, Coagulant Winter Cherry.

Indian Rennet displays an upright, branching shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Indian Rennet produces small tubular flowers in shades of purple or green.

Leaf size: approximately 4 inches.

Water a young or newly planted Indian Rennet every 7–10 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.

Indian Rennet thrives in full sun to partial shade.

Withania coagulans tolerates temperatures of 60–80°F. Indian Rennet prefers humidity levels of 40–60%.

Well-draining sandy loam with added compost for nutrients. Good drainage is essential for Indian Rennet to prevent waterlogging, which leads to root rot and fungal issues.

Feed Indian Rennet 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 compost for nutrients. Avoid low spots where water collects after rain.

Indian Rennet is suited to USDA Zone 9a – 11b.

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.

Indian Rennet 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.

Prune Indian Rennet 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.

Indian Rennet is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Indian Rennet can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to shrubby bladder cherry plant care, which shares the same genus.

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

Indian Rennet grows outdoors in USDA Zone 9a – 11b. It survives winters down to planting zone 9a. Indian Rennet is native to Afghanistan and the Indian subcontinent. In cooler regions, grow Indian Rennet as a houseplant or bring it indoors before the first frost.
