The fruits of cawesh appear in small bunches of two to three on the branches. As the fruits are set in clusters, they are usually small in size.

Habitat and cultivation

Apparently, this species (A. scleroderma) grows wild in a vast area ranging from the Atlantic slope in Campeche right up to Honduras. However, in Guatemala, this species is grown in a relatively small area on the Pacific slope between an altitude of 300 m and 1000 m. This region is known as Bocacosta and the soil here is volcanic and very fertile. Moreover, this region has a very brief dry season and receives an annual rainfall of 4000 mm.

Different from the seeds of other fruits of plants belonging to the Annona family, cawesh seeds sprout readily when they are fresh. The germination rate is as high as 90 per cent in a month and they also do not require any pre-planting treatment. However, stored cawesh seeds normally take roughly six months to take root, especially the seeds that have been kept aside for two to three months. Cawesh trees propagated from seeds start bearing fruits after four years. By this time, these trees attain a height of anything between 4 m and 6 m.

For instance, in Australia this species (A. scleroderma) has an excellent growth, especially when it is grafted on the stocks of Rollinia mucosa and A. muricata.

After picking the fruits, they need to be stored indoors to allow them some time to ripen completely. The harvesting of cawesh fruits is somewhat similar to that of custard apples.
