Castanedia santamartensis Plant Care

Castanedia santamartensis (Castanedia santamartensis) belongs to the Asteraceae family within the Castanedia genus. Castanedia santamartensis is native to the Sierra Nevada de Santa Marta of northeastern Colombia.

Castanedia santamartensis displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Castanedia santamartensis produces small daisy-like flowers in shades of yellow and orange.

Leaf size: approximately 6 inches.

Water a young or newly planted Castanedia santamartensis 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.

Castanedia santamartensis thrives in full sun to partial shade.

Castanedia santamartensis tolerates temperatures of 60–75°F. Castanedia santamartensis prefers humidity levels of 40–60%.

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

Feed Castanedia santamartensis 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Castanedia santamartensis is suited to USDA Zone 13a.

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.

Castanedia santamartensis can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Castanedia santamartensis 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.

Castanedia santamartensis 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.
