Delicious Fruit from my backyard

Well I picked 14 star fruit today. The yellow 5 corner variety. AMazing i bought the tree 6 years ago for a few dollars and now it produces fruit year long. It has the best smell and fresh juice when they are ripe. We can slice them into star shape and use them to decorate things.
This is a grea tree to plant and we dont have to use any spray or pesticide. Lucky. I wonder what is important in the care and pruning of a star fruit tree. Does anyone know? And what are some organic methods for dealing with the pesky worms. If left to long to ripen the get worms in some of them. Will wrapping in a plastic bag help? I used this method on my Guava trees and we are also eating guava for the first time in 7 years. We have had the tree the whole time but they always went wrotten. This last month i used plastic 7 eleven grocery bags to wrap them and they didnt rot as bad. Does anyone know what i need to do? Please comment
