Perennial Peanut Plant Care

Perennial Peanut (Arachis glabrata) belongs to the Fabaceae family within the Arachis genus. Perennial Peanut is native to Argentina, Brazil, and Paraguay vegetation. Perennial Peanut is also known as Rhodes Grass, Forage Peanut, Arachis diogoi f. sericeovillosa.

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

Leaf size: approximately 1 inches.

Water a young or newly planted Perennial Peanut 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.

Perennial Peanut thrives in full sun.

Arachis glabrata tolerates temperatures of 60–85°F. Perennial Peanut 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 Perennial Peanut to prevent waterlogging, which leads to root rot and fungal issues.

Feed Perennial Peanut 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.

Perennial Peanut is suited to USDA Zone 8b – 11b.

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.

Perennial Peanut can spread to about 2 ft (0.6 m). 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 Perennial Peanut 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.

Perennial Peanut is hardy down to USDA zone 8b, 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 trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Perennial Peanut can be propagated through seeds, runners. Similar propagation techniques also apply to peanut plant plant care, which shares the same genus.

Perennial Peanut 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.
