Origin It is believed to be a native of the West Indies but was carried in early times through Central America to southern Mexico.
DescriptionClosely related to sugar apples, the flavor of custard apple has been described as a cross between papaya, vanilla and pineapple. The ripe fruit is sweet and pleasant in flavor.
Growth HabitatTropical climate but with cooler winters than those of the west coast of Malaysia. This species is less drought-tolerant than sugar apple and prefers more humid atmosphere.
FoliageThe slender leaves are not hairy, straight and pointed at the apex (in some varieties wrinkled), 10 cm to 20 cm long and 2 cm to 7 cm wide.
FlowersYellow-green flowers, generally in clusters of three or four, 2 cm to 3 cm diameter, with three long outer petals and three very small inner ones.
FruitsFruit is 8-16cm in diameter, can be symmetrically heart-shaped, lopsided, irregular, nearly round, or oblate with a deep or shallow depression at the base. The skin is thin but tough, turns yellow or brownish when ripe, with a pink, reddish or brownish-red blush. There is a thick, cream-white layer of custard like flesh beneath the skin surrounding the juicy segments. In each segment there is a single, hard, dark-brown or black, glossy seed, oblong and smooth, less than a half of inch long. There are between 55 and 76 seeds in a fruit. The unripe fruit is rich in tannin.
Harvest The fruit is harvested after its colour changes patterns although in some cultivars this does not occur and ripeness is determined by feel. The skin is very thin and the fruit must therefore be handled carefully.
SoilThe custard apple does best in low-lying, deep, rich soil with ample moisture and good drainage. It grows to full size on oolitic limestone but is less productive in light sand and other types of soil
PruningPrune for vegetative growth and shape for aeration and light penetration. Pruning branches during the second to fourth year can stimulate the growth of secondary and tertiary branches.
FertilizationThe tree is fast-growing and responds well to mulching, organic fertilizers and to frequent irrigation if there is dry weather during the growing period.
PropagationUsually by seeds. There are few named varieties and better strains are propagated by air layering and grafting.
The custard apple is a good source for important minerals such as calcium, phosphorus and potassium and also vitamin C.
