Tepary Bean Plant Care

Tepary Bean (Phaseolus acutifolius) belongs to the Fabaceae family within the Phaseolus genus. Tepary Bean is native to the southwestern United States and Mexico that has been grown there by the native peoples since pre-Columbian times. Tepary Bean is also known as Tepary.

Tepary Bean displays a vining or bushy habit growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Tepary Bean produces small white or purple flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Tepary Bean every 3–5 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.

Tepary Bean thrives in full sun.

Phaseolus acutifolius tolerates temperatures of 65–85°F. Tepary Bean prefers humidity levels of 40–60%.

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

Feed Tepary Bean 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.

Choose a spot with full sun and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Tepary Bean is suited to USDA Zone 13b.

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.

Tepary Bean 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 Tepary Bean 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.

Tepary Bean 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.

Tepary Bean can be propagated through seeds. Similar propagation techniques also apply to green bean plant plant care, which shares the same genus.

Tepary Bean is susceptible to aphids, bean beetles, leafhoppers. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Tepary Bean grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Tepary Bean is native to the southwestern United States and Mexico that has been grown there by the native peoples since pre-Columbian times. In cooler regions, grow Tepary Bean as a houseplant or bring it indoors before the first frost.
