Leucaena magnifica

Cultivation Details

Leucaena magnifica is a tropical species and occurs in areas with 800 - 1,200mm rainfall and a 5 - 6 month dry season^[1]. Leucaena species generally require a sunny position. They are often found in the wild on poor, shallow and dry soils, usually overlying a calcareous rock. Most of them do not thrive on acid soils. Most species experience a long dry season and are more or less drought tolerant. The plant is moderately susceptible to damage from psyllids^[1]. The unripe seedpods are harvested by climbing the trees and lopping the terminal branches or groups of pods, often crudely, with machetes, small knives or cutting poles. Annual pollarding in this way apparently causes only limited damage to the trees which resprout and fruit annually^[1]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby^[2].
