Cestrum tomentosum Plant Care

Cestrum tomentosum (Cestrum tomentosum) belongs to the Solanaceae family within the Cestrum genus.

Cestrum tomentosum displays a fast-growing shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Cestrum tomentosum produces tubular flowers in shades of red, orange, or yellow.

Leaf size: approximately 6 inches.

Water a young or newly planted Cestrum tomentosum every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Cestrum tomentosum thrives in full sun to partial shade.

Cestrum tomentosum tolerates temperatures of 50–85°F. Cestrum tomentosum prefers humidity levels of 40–70%.

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

Feed Cestrum tomentosum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 to partial shade and well-draining, fertile soil with added compost for nutrients. Avoid low spots where water collects after rain.

Cestrum tomentosum is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Cestrum tomentosum can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cestrum tomentosum 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 tree in one year.

Cestrum tomentosum is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cestrum tomentosum can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to night-blooming jessamine plant care, which shares the same genus.

Cestrum tomentosum 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.

Cestrum tomentosum grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Cestrum tomentosum as a houseplant or bring it indoors before the first frost.
