Mammee apple is limited to tropical or near tropical moist to wet climates[]. It grows best in the lowlands, but can succeed at elevations up to 1,000 metres[]. It grows best in areas where annual daytime temperatures are within the range 24 - 30°c, but can tolerate 12 - 35°c[]. When dormant, the plant can survive temperatures down to about -2°c, but young growth can be severely damaged at 0°c[]. It prefers a mean annual rainfall in the range 1,200 - 1,800mm, but tolerates 800 - 2,600mm[].
Prefers a position in full sun or light shade[]. Prefers a deep, rich, well-drained sandy loam[]. Prefers a pH in the range 6 - 6.5, tolerating 5.5 - 8[].
Trees can produce their first crop in 6 - 10 years from seed[].
Good trees can produce 300 - 400 fruits per year[].
There are some named varieties[].
One report says that the plant is dioecious[], others that it is monoecious.
In some forms of this plant, the flowers produced are predominantly female and the tree fruits heavily, in other forms there can be a predominance of male flowers and fruit yields are much lower[].

Edible Uses

The fruits can be as large as a child's head and weigh up to 2 kilos[, ].

All parts of the plant have insecticidal properties; infusions of the powdered seeds and gum from the bark and green fruit rind are used as insecticides to kill ticks, fleas and jiggers[, ]. Mammee leaves are wrapped around young tomato plants when setting them in the ground to protect them from mole crickets and cutworms[]. Various extracts from the fruit, bark, leaves or roots are toxic to moths, beetle larvae and also to bugs[]. Seed extracts are toxic to fish, chicks and hogs[]

The heartwood is reddish or purple-brown; the sapwood much lighter in colour. Texture is medium; the grain is fine in one report, whilst another says that it is frequently interlocked and irregular; the surface of this attractive wood often is flecked with small, dark, oily, exudations. The wood is hard; heavy; strong; fairly resistant to decay but very susceptible to termites. Air-seasoning is moderate in rate but very difficult, and the amount of degrade is considerable. It is easy to work; has an attractive grain and polishes well; planing, turning, boring, and mortising are good; shaping and resistance to screw sjjlitting are excellent ; and sanding is poor. The wood is useful in cabinetwork, it is valued for pillars, rafters, decorative features of fine houses, interior sheathing, turnery and posts[, ].
The wood is used for fuel[].

Propagation

Seeds are the usual means of propagation and they germinate in 1 - 4 months with a 97% rate. Seeds sprout readily in leaf-mulch under the tree. Grown under light shade, seedlings reach 40 - 50cm and are ready to out-plant 3 - 5 months after sowing.[].
