There are several types of fruit trees, including cherry, apple, lemon, orange, grapefruit, plum, peach, lime, apricot, berries, pear, crab apple and passion fruit. They all suffer from similar problems, such as pests, animals and diseases, but these usually vary from tree species to species.
Pests commonly infest fruit trees and can include fruit flies, plant bugs, coddling moths, fruit moths, leaf rollers, borers and aphids. Slugs are also common pests. These pests can be prevented with nets or deterrent sprays. Some fruit trees need to be protected before they blossom, while others need it after.
Most fruit trees that become infected with a disease get it from a certain fungus or bacteria. There are several types of fruit tree diseases, so it is important to get it diagnosed properly based on the symptoms and time of year the fruit tree falls ill. These diseases may include things such as scabs or blight. You can successfully treat about half of these fruit tree diseases with preventative measures and treatments, but some diseases can completely kill a tree. Common diseases include apple scab, black knots on cherry trees and fire blight on pear trees.
Some animals think fruit tastes good, just like humans do. These include flying foxes, flying squirrels, squirrels and mice. These pests can bore holes into trees, gnaw on branches and early growth, and create homes in the trees so they are the ones getting the majority of the fruit. You can prevent these pests from accessing fruit with nets, or by planting the tree away from other trees with outstretched branches, or by encircling the trunk with several feet of mesh wire.
