Acacia baessleri Plant Care

Acacia baessleri (Vachellia baessleri) belongs to the Fabaceae family within the Vachellia genus. Acacia baessleri is native to Kenya, Tanzania. Acacia baessleri is also known as Senegalia baessleri.

Acacia baessleri displays a fast-growing tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Acacia baessleri produces small, fluffy, pale yellow to cream-colored flowers in spherical clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Acacia baessleri 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.

Acacia baessleri thrives in full sun.

Vachellia baessleri tolerates temperatures of 60–85°F. Acacia baessleri prefers humidity levels of 40–70%.

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

Feed Acacia baessleri every 8 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.

Choose a spot with full sun and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Acacia baessleri is suited to USDA Zone 13a.

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.

Acacia baessleri can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Acacia baessleri 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.

Acacia baessleri 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.

Acacia baessleri can be propagated through seeds, root cuttings. Similar propagation techniques also apply to bullhorn acacia plant care, which shares the same genus.

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

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