Horovitzia cnidoscoloides Plant Care

Horovitzia cnidoscoloides (Horovitzia cnidoscoloides) belongs to the Caricaceae family within the Horovitzia genus. Horovitzia cnidoscoloides is native to the cloud forest of Sierra de Juarez in Oaxaca, Mexico at elevations of 800 to 1600 meters.

Horovitzia cnidoscoloides displays a tall, upright tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Horovitzia cnidoscoloides produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Horovitzia cnidoscoloides 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.

Horovitzia cnidoscoloides thrives in full sun to partial shade.

Horovitzia cnidoscoloides tolerates temperatures of 65–85°F. Horovitzia cnidoscoloides prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Horovitzia cnidoscoloides to prevent waterlogging, which leads to root rot and fungal issues.

Feed Horovitzia cnidoscoloides 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 loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Horovitzia cnidoscoloides is suited to USDA Zone 13b.

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.

Horovitzia cnidoscoloides can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Horovitzia cnidoscoloides 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.

Horovitzia cnidoscoloides 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.

Horovitzia cnidoscoloides can be propagated through stem cuttings, air layering, division.

Horovitzia cnidoscoloides grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Horovitzia cnidoscoloides is native to the cloud forest of Sierra de Juarez in Oaxaca, Mexico at elevations of 800 to 1600 meters. In cooler regions, grow Horovitzia cnidoscoloides as a houseplant or bring it indoors before the first frost.
