Peanut Plant Plant Care

Peanut Plant (Arachis hypogaea) belongs to the Fabaceae family within the Arachis genus. Peanut Plant is native to South America. Peanut Plant is also known as Peanut, Groundnut, Earthnut.

Peanut Plant displays a low-growing spreading growth habit, reaching up to 2 ft tall with a spread of approximately 1 ft. Peanut Plant produces small yellow pea-like flowers.

Water a young or newly planted Peanut Plant every 7–10 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.

Peanut Plant thrives in full sun.

Arachis hypogaea tolerates temperatures of 70–90°F. Peanut Plant prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy loam with added organic matter. Good drainage is essential for Peanut Plant to prevent waterlogging, which leads to root rot and fungal issues.

Feed Peanut Plant every month 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 and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Peanut Plant is suited to USDA Zone 11a – 13b.

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.

Peanut Plant can spread to about 1 ft (0.3 m) and reach about 2 ft (1 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Peanut Plant 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.

Peanut Plant is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Peanut Plant can be propagated through seeds, runners.

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

Peanut Plant grows outdoors in USDA Zone 11a – 13b. It survives winters down to planting zone 11a. Peanut Plant is native to South America. In cooler regions, grow Peanut Plant as a houseplant or bring it indoors before the first frost.
