Permaculture uses
Leucaena leucocephala is a valuable multipurpose tree in permaculture. Its nitrogen-fixing abilities improve soil fertility, and it serves as a living fence, windbreak, and shade tree. Young leaves and pods are edible when properly prepared to reduce mimosine content; they are used as livestock fodder. The wood is used for fuel, construction, and pulpwood. Some cultivars are specifically bred for higher palatability and lower mimosine levels for improved forage. It can also be used for green manure and composting.
Permapeople description
Leucaena leucocephala is a fast-growing tree in the subfamily Mimosoideae
Botanical description
Leucaena leucocephala is a fast-growing, leguminous tree native to Central America and Mexico. It can grow up to 20 meters tall. The leaves are bipinnately compound, with small, lanceolate leaflets. The flowers are white and arranged in globular heads. The pods are flat, brown, and contain numerous seeds. The tree has a deep taproot, enabling it to access water in dry conditions. It is adaptable to a wide range of soil types, but prefers well-drained soils.
Companion planting
Leucaena leucocephala is a nitrogen fixer, so it benefits plants that require nitrogen-rich soil. However, due to its rapid growth and potential invasiveness, careful consideration is needed when planting it near other plants. It can compete for sunlight and resources. Favorable associations include grasses and other nitrogen-loving species planted below the canopy. Avoid planting near sensitive native species.
Propagation methods
Leucaena leucocephala can be propagated by seeds, stem cuttings, and root suckers. Seed scarification is often necessary to improve germination rates. Cuttings should be taken from young, actively growing stems. Root suckers can be transplanted directly.
History and traditions
Leucaena leucocephala has a long history of use in its native regions for food, fodder, and fuel. It has been introduced to many tropical and subtropical regions worldwide. In some areas, it has become an invasive species due to its rapid growth and prolific seed production. Traditionally, various parts of the plant have been used for medicinal purposes, including treating intestinal worms and skin ailments.
Usage calendar
Flowering occurs throughout the year in tropical climates. Pods mature several months after flowering. Planting is best done during the rainy season. Pruning can be done at any time of year to control size and shape.
