Black wattle - Acacia mangium (Taxonomy, Characteristics, Invasive, Images)

Black wattle

Also known as: Mangium, Brown salwood

A member of the pea family, black wattle is a flowering tree. The timber of this tree is frequently used for furniture making, and the tree itself is often used for reforestation projects. This tree grows larger near the equator but will not get as large when it is cultivated further away from the equator.

Distribution of Black wattle

Distribution Map

Black wattle is a plant with a native range focused on certain Southeast Asian regions. It has since spread to various parts of subtropical and tropical areas on several continents. Though black wattle is valued for certain applications in its introduced range, it is sometimes thought to be competitive in local landscapes, potentially impacting ecosystems, especially in certain areas where it is considered invasive.

Weed Control

Black wattle is a flowering tree, useful for improving soil fertility and wood manufacturing. However, it's high adaptability and fast growth have made it an invasive species in some parts of the world.

How to Control It

The most effective way of controlling black wattle spread is through seed-eating fungi and insects. Girdling is an easy and organic way to deal with mature plants. It will stunt the tree's growth and eventually kill it. The dead tree can then be cut down. Chemical control is also an option. Basal bark sprays and stem injections can be very effective in preventing black wattle regrowth. It's best to apply herbicides from late autumn to early spring. If you opt for chemical control, consult an agricultural expert to find the best active substance and application method for your geographic area.

Garden Soil

Soil Type

Water: Originating from humid Australasia, black wattle is drought-tolerant, requiring watering every 2-3 weeks. As a rapid grower and nitrogen-fixer used in reforestation, it thrives in full sun and benefits from rainwater during its active growing season.

Fertilize: For black wattle, use balanced fertilizers for overall health; high-nitrogen options enhance growth. Fertilize every 3-4 months according to growth stage. Seasonal variations influence nutrient uptake, so adjust applications for optimal results and avoid over-fertilizing to prevent root burn.

Pruning: Pruning black wattle during early to late winter fosters healthy growth by removing dead branches and shaping the plant. This practice enhances airflow, promotes strong branching, and aids in disease prevention, ideally occurring during black wattle's dormant period to minimize stress and ensure vigorous growth.

Propagation: Black wattle is a fast-growing tree valued for its timber and nitrogen fixation. It prefers well-drained soils and full sunlight. Effective propagation involves semi-hardwood cuttings with rooting hormones in a sterilized, porous medium, while high humidity and warmth support successful rooting.
