Guatteria stenopetala Plant Care

Guatteria stenopetala (Guatteria stenopetala) belongs to the Annonaceae family within the Guatteria genus. Guatteria stenopetala is native to Venezuela.

Guatteria stenopetala displays an upright, bushy tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Guatteria stenopetala produces small, greenish-yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Guatteria stenopetala every 7–14 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.

Guatteria stenopetala thrives in partial shade to full sun.

Guatteria stenopetala tolerates temperatures of 65–85°F. Guatteria stenopetala prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for Guatteria stenopetala to prevent waterlogging, which leads to root rot and fungal issues.

Feed Guatteria stenopetala 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 partial shade to full sun and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Guatteria stenopetala 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.

Guatteria stenopetala 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 Guatteria stenopetala 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.

Guatteria stenopetala 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.

Guatteria stenopetala can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to guatteria atabapensis plant care, which shares the same genus.

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

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