White Spots On Lemon Tree Leaves- Causes

Are you a gardener with a lemon tree that has developed white spots on its leaves? If so, you may be wondering what is causing the problem. Let’s dive in to find the reasons behind those white spots.

Cottony Cushion Scale

The cottony cushion scale is one potential cause of white spots on lemon tree leaves. This is a type of insect that feeds on the sap of plants. The female cottony cushion scale produces a white, waxy substance that covers the tree body and acts as a protective barrier. This substance can also transfer to the plant’s leaves, causing white spots. You can use an insecticide or hire an exterminator to get rid of the cottony cushion scale. 

Powdery Mildew

Another potential cause of white spots on lemon tree leaves is powdery mildew. Powdery mildew is a type of fungus that affects many types of plants, including lemon trees. The fungus grows on the leaves’ surface and produces a white powder. You can use a fungicide or hire an exterminator to get rid of powdery mildew. 

Whiteflies

Another potential cause of white spots on lemon tree leaves is whiteflies. Whiteflies are small flying insects that feed on the sap of plants. They are usually white with yellow stripes or spots. You can use an insecticide or hire an exterminator to get rid of whiteflies. 

Citrus Cankers

Another potential cause of white spots on lemon tree leaves is citrus cankers. Citrus cankers are caused by a bacteria called Xanthomonas citri subspiralis. This bacteria infects the branches and leaves of citrus trees, causing them to develop raised bumps or lesions.

The bumps eventually rupture and ooze out a sticky substance that dries into crusty scabs. The scabs are usually black in color but can also be brown, red, or tan. Hire an arborist or tree surgeon to remove the infected branches and leaves from your lemon tree to get rid of citrus cankers. Uprooting the entire tree may also be necessary in some cases. 

There are several potential causes of white spots on lemon tree leaves. In most cases, the solution is to use an insecticide or fungicide. However, in some cases, such as with citrus cankers, you may need to hire an arborist or tree surgeon to remove the infected branches and leaves from your lemon tree. Uprooting the entire tree may also be necessary in some cases.

How To Treat White Spots On Lemon Tree Leaves?

While a lemon tree with white spots on its leaves can be unsightly, the good news is that this condition is not deadly to the tree and can be easily treated. The most common cause of white spots on lemon tree leaves is a fungal disease called powdery mildew.

This disease is caused by a lack of air circulation around the leaves, which creates the perfect environment for fungus to thrive. Read on to learn more about how to treat powdery mildew on your lemon tree.

Treating Powdery Mildew on Lemon Trees

Powdery mildew is best treated with a fungicide that contains either sulfur or neem oil. These fungicides can be found at most hardware stores or garden centers.

To apply the fungicide, mix it according to the instructions on the label and then apply it evenly to the affected leaves using a garden sprayer. You will need to reapply the fungicide every 7-10 days until the powdery mildew has disappeared.

In addition to treating your lemon tree with fungicide, you can also help prevent powdery mildew from occurring in the first place by increasing air circulation around the leaves.

This can be done by pruning any branches touching the ground and spacing your lemon trees further apart if they are planted close together. Lastly, ensure to water your lemon trees at their base rather than above, as this will help keep the leaves dry and less susceptible to fungus growth.

By following these tips, you can easily get rid of powdery mildew on your lemon trees and prevent it from coming back in the future.
