How to Grow a Sugar Apple Tree
Sugar apples are also known as anon, custard apple and sweetsop. They are a member of the Annonaceae family. Sugar apples grow best in warm tropical locations and are a common fruit tree in the southern regions of Florida.
By following some basic tips in planting and caring for your sugar apple tree, in just a few years you should be harvesting its fruit.
Choose a healthy tree from your local nursery. You may also grow one from seed. The seeded varieties seem to grow better and produce better fruit than the seedless types. Most trees are grown in 3-gallon containers. Make sure the sugar apple is no taller than 4 feet from the surface of the soil in the container. Large trees growing in small containers can become root bound and never grow correctly even when planted in the ground. Pick a location in your yard that gets full sun, doesn't flood, is wind protected and is away from any structures and power lines. If left unpruned, sugar apple trees can obtain a height of 20 feet.
Dig a hole that is 3 times the diameter and depth of the container holding the tree. Loosen the surrounding soil, making it easier for the roots to spread out. It's not recommended to add topsoil, compost or any type of fertiliser to soil.
Remove the tree from the container and place it in the hole, making sure the top of the plant's soil is level with the ground. Planting the tree too deep will weaken it. Fill the hole with the excavated dirt. Stomp down the soil around the tree to get rid of any air pockets and water the area well.
Fertilise your tree about every 2 months with a mixture of 6-6-6 or 8-3-9. By placing mulch around the base of the sugar apple tree, more moisture will be retained in the soil around the roots. Water your tree regularly, but don't overdo it. Sugar apples are drought hardy and don't tolerate flooded conditions.
