Knowing how to recognize fruit problems is not easy and it can take quite a bit of time to familiarize yourself with the signs, warnings and characteristics of each type of fruit-related ailment. However, not all citrus tree fruit problems are common in North American regions.

The two most common types of fruit diseases are referred to as fruit drop and citrus scab. Here is a brief description of each:

Fruit Drop: The signs of severe fruit drop are quite obvious. Early in the fruit formation period, small immature fruit will fall from the tree in large quantities. Though it is normal for a fruit tree to drop some of its fruit as a self-thinning process, an abundance of fallen fruit is a much more serious issue. Fruit drop is most commonly caused by stress, late frost, lack of water, too much water or even inadequate fertilization.

To avoid Fruit Drop consider fertilizing your tree annually in the spring growing season. It is also imperative to use a fertilizer which is specifically designed with the needs and requirements of citrus trees in mind.

Citrus Scab: This fruit infection is common, and can lead to wasted fruit as well as premature leaf drop. Citrus scab can be identified by the accumulation of small brown raised marks on the skin of maturing fruit. Citrus scab may also result in brown, dried areas on leaves and delayed growth and development.

Citrus Scab and other similar citrus tree fruit problems are caused by overly-damp conditions and excessive watering during wetter seasons which lead to a build up of aggressive fungus. Controlling citrus scab is not difficult for the most part and all that is needed is a fungicide spray or treatment.

It is also recommended that you refrain from watering your citrus tree with a sprinkler, as a drip hose near the base of the tree is much more effective and will prevent the spread of citrus scab and other citrus tree fruit problems.
