Weed Control
Gum arabic tree is an evergreen tree which establishes itself quickly and is widely used in agroforestry, for tanning, as fuelwood and timber. Even though it has a variety of uses, this plant is considered invasive in many areas outside its native range.
How to Control It
Control and management of gum arabic tree is not only difficult, but also costly. Since it is often transported deliberately by individuals who wish to use it as fodder for livestock or for other applications, community education is one of the best methods of control. Quarantine cattle and sheep if they moved within an infested area to prevent the spread of seeds. Mechanical removal of this plant is usually performed after a chemical treatment. Gum arabic tree is resistant to grazing, and can quickly regenerate after being damaged, which is why simply cutting it down is not efficient enough. Herbicides can be applied onto the basal bark and cut stumps, or injected into the plant. Before picking the herbicide, consult an agricultural expert to determine which active substance and application method is best for your geographic region.

Water:
Gum arabic tree thrives in arid environments with high drought tolerance and minimal watering needs, requiring care only every 2-3 weeks. It prefers well-drained soil and temperatures similar to its native habitat, with reduced watering during winter dormancy to avoid waterlogging.
Fertilize:
For optimal growth, gum arabic tree requires balanced fertilizers, particularly high in nitrogen during vegetative growth. Fertilize biannually in spring and fall, applying evenly around the drip line. Adjust ratios seasonally; use gloves and follow package instructions for safe application.
Pruning:
Gum arabic tree features a unique canopy and thorny branches, benefiting from early spring pruning before new growth. Remove dead or crossing branches to improve airflow and sunlight. Thinning enhances health, size, and shape. Always use sanitized tools and prune above buds or junctions.
Propagation:
Gum arabic tree, native to Africa and the Indian subcontinent, is valuable economically and environmentally. Propagation mainly occurs through cuttings from healthy parent trees. A clean angled cut and rooting hormone aid root development. Plant in well-draining soil, maintaining moisture and shade until established.
