Crotalaria digitata Plant Care

Crotalaria digitata (Crotalaria digitata) belongs to the Fabaceae family within the Crotalaria genus. Crotalaria digitata is native to India.

Crotalaria digitata displays an upright, branching shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Crotalaria digitata produces showy yellow, orange, or red pea-like flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Crotalaria digitata 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.

Crotalaria digitata thrives in full sun to partial shade.

Crotalaria digitata tolerates temperatures of 65–85°F. Crotalaria digitata prefers humidity levels of 40–60%.

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

Feed Crotalaria digitata every 6 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 to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Crotalaria digitata 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.

Crotalaria digitata can spread to about 3 ft (0.9 m) and reach about 4 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 Crotalaria digitata 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.

Crotalaria digitata 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.

Crotalaria digitata can be propagated through seeds. Similar propagation techniques also apply to rattlepod plant care, which shares the same genus.

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

Crotalaria digitata grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Crotalaria digitata is native to India. In cooler regions, grow Crotalaria digitata as a houseplant or bring it indoors before the first frost.
