Bullhorn acacia

Bullhorn acacia (Vachellia cornigera) is a tree native to Central America named for the horn-shaped spines found on its branches. The hollow spines shelter ant colonies that have developed a symbiotic relationship with the tree. These ants defend the tree from herbivores and the tree grows detachable nutrient-rich pods on which the ants feed.

Care Guide for Bullhorn acacia

Every 2-3 weeks

Water

Full sun

Sunlight

15 - 38 ℃

Ideal Temperature

Water: Originating from arid regions, bullhorn acacia exhibits high drought tolerance and requires minimal moisture. Water once every 2-3 weeks, favoring infrequent but deep hydration in well-draining soil. Thriving in warm climates, bullhorn acacia prefers rainfall that mimics its native dry conditions.

Fertilize: For bullhorn acacia, use high-nitrogen fertilizers biannually in spring and late summer, at 1 pound per inch of trunk diameter around the drip line, to support growth and thorn development. Avoid winter fertilization. Employ slow-release formulas to prevent root burn and ensure a steady nutrient supply.

Pruning: Pruning bullhorn acacia in early spring improves shape, air circulation, and removes dead branches. Trim crossing branches for an open canopy, stimulating new growth and maintaining health. Regular inspections and trimmings ensure bullhorn acacia retains its unique appearance and prevents overgrowth.

Propagation: Bullhorn acacia propagation is successful through semi-hardwood cuttings from healthy parents. Use sharp, sterilized tools, apply rooting hormone, and place in a well-draining medium. Maintain moisture and indirect light until roots develop, then transplant to a larger pot or suitable ground.
