Rhomboideum Pepper Plant Care

Rhomboideum Pepper (Capsicum rhomboideum) belongs to the Solanaceae family within the Capsicum genus. Rhomboideum Pepper is native to Mexico, Central America, and Andean region of South America. Rhomboideum Pepper is also known as Wild Bush Pepper.

Rhomboideum Pepper displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Rhomboideum Pepper produces small white or purple flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Rhomboideum Pepper 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.

Rhomboideum Pepper thrives in full sun.

Capsicum rhomboideum tolerates temperatures of 65–85°F. Rhomboideum Pepper prefers humidity levels of 40–70%.

Well-draining, fertile soil with added compost. Good drainage is essential for Rhomboideum Pepper to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rhomboideum Pepper 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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

Rhomboideum Pepper 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.

Rhomboideum Pepper 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 Rhomboideum Pepper 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.

Rhomboideum Pepper 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.

Rhomboideum Pepper can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to bell pepper plant care, which shares the same genus.

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

Rhomboideum Pepper grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Rhomboideum Pepper is native to Mexico, Central America, and Andean region of South America. In cooler regions, grow Rhomboideum Pepper as a houseplant or bring it indoors before the first frost.
