If you're a citrus tree owner, you may have noticed that the leaves on your tree are starting to fall off. It's important to understand why this is happening so that you can take appropriate action and prevent further damage to your trees. In this article, we'll explore the reasons behind leaves falling off citrus trees and what you can do about it.

Citrus Tree Physiology

Citrus trees are evergreens that require a lot of water and nutrients to thrive. They have shallow root systems that absorb water quickly, but they also lose water quickly through their leaves. As a result, citrus trees need consistent watering to maintain healthy foliage and fruit production.

During the growing season, citrus trees produce new leaves, which are essential for photosynthesis and fruit production. As these leaves mature, they start to produce sugars and other nutrients that are necessary for the growth and development of the fruit. If the tree does not receive enough water or nutrients, the older leaves will start to yellow and eventually fall off.

Lack of Water

The most common reason for leaves falling off citrus trees is due to lack of water. If your tree is not receiving enough water, the leaves will start to wilt and eventually turn yellow or brown. This is because the tree is using all of its available water to maintain its roots and fruit, leaving no water for the leaves.

If you notice that your tree's leaves are falling off and the soil is dry, it's important to water your tree immediately. Make sure to give your tree a deep watering to ensure that the water reaches the roots.

Nutrient Deficiency

Citrus trees require specific nutrients to remain healthy and produce fruit. These include nitrogen, phosphorus, and potassium, as well as trace minerals such as iron and zinc. If your tree is lacking in any of these nutrients, the leaves will start to yellow and fall off.

To address nutrient deficiencies, you can fertilize your tree with a citrus-specific fertilizer. These fertilizers are formulated to provide the specific nutrients that citrus trees require. You can also amend your soil with compost or other organic matter to improve its nutrient content.

Pests and Diseases

Pests and diseases can also cause leaves to fall off citrus trees. Common pests include spider mites, aphids, and scale insects. These pests feed on the leaves and suck sap from the tree, which can cause the leaves to wilt and fall off.

Diseases such as citrus canker and greening can also cause leaves to fall off citrus trees. These diseases are caused by bacteria and can be difficult to treat. If you suspect that your tree has a disease, it's important to contact a professional arborist or horticulturist for advice.

Leaves falling off citrus trees can be a sign of several different problems, including lack of water, nutrient deficiency, pests, and diseases. By understanding the causes of leaf drop, you can take appropriate action to keep your trees healthy and productive. Make sure to give your trees enough water and nutrients, fertilize regularly, and monitor for signs of pests and diseases. With proper care, your citrus trees will continue to produce bountiful fruit for years to come.
