Phaseolus glabellus Plant Care

Phaseolus glabellus (Phaseolus glabellus) belongs to the Fabaceae family within the Phaseolus genus. Phaseolus glabellus is native to Mexico, with red flowers.

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

Leaf size: approximately 6 inches.

Water a young or newly planted Phaseolus glabellus 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.

Phaseolus glabellus thrives in full sun.

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

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

Feed Phaseolus glabellus 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.

Phaseolus glabellus 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.

Phaseolus glabellus 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 Phaseolus glabellus 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.

Phaseolus glabellus 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.

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

Phaseolus glabellus 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.

Phaseolus glabellus grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Phaseolus glabellus is native to Mexico, with red flowers. In cooler regions, grow Phaseolus glabellus as a houseplant or bring it indoors before the first frost.
