Cultivation Details
Leucaena confertiflora is native to high, dry, inland hills and plateaux of southern Mexico, where it can experience regular moderate frosts for up to 3 monhs of the year. It experiences a mean annual rainfall in the range of 500 - 700mm, with a dry season of up to 7 months[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. A slow-growing plant[1]. The plant responds well to coppicing[2, 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].
Propagation
Seed - it has a hard seedcoat and may benefit from scarification before sowing in order to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. The seed retains its viability for a long period if stored under conditions of less than 10 % moisture content at less than 4°c in hermetically sealed containers[2].
