Custard apples are a subtropical fruit known for their creamy texture and sweet flavor. Growing them locally is not difficult due to our warm climate, fertile soils, and reliable rainfall. Custard apples prefer a frost-free environment, as frost can cause damage to the trees and in particular young plants. Our local climate with our temperatures between 20°C and 30°C provides the warmth needed for the trees to flower and set fruit.
Humidity is important for fruit development, as custard apples prefer moderate to high humidity levels. Our proximity to the coast offers the necessary moisture and humidity. Custard apples perform best in well-drained soils with a pH range between 5.5 and 7.5. That PH is typical in our local soils.
When planting, choose a location that receives full sunlight for at least 6-8 hours a day. Custard apple trees are sensitive to water logging, so ensure that the site has good drainage to avoid root rot. If the natural drainage is poor, consider planting on mounds or raised beds.
When planting, start with a large hole and add plenty of organic matter, such as compost or well-rotted manure, to improve soil structure and fertility. Ensure that the soil is loose and not compacted. This ensures good root growth and water penetration. Custard apples also benefit from mulching, which helps retain soil moisture, regulates the temperature, and suppresses weeds.
Planting is ideal in late spring, after the risk of frost has passed. Custard apples have moderate water requirements. They need consistent moisture during the growing season, particularly during flowering and fruit set. Fertilizing custard apple trees helps with healthy growth and fruit production. We apply our compost yearly and then some additional mulch.
Pruning is essential to maintain a healthy tree structure and promote good fruit production. Custard apples tend to grow as multi-stemmed trees, so we always avoid having a central leader and prune so we have an open vase shape. Regular pruning helps to remove dead or diseased wood, improves airflow, and allows sunlight to reach the inner parts of the tree, reducing the risk of fungal diseases.
