Lemon Tree Problems: Treating Common Lemon Tree Diseases
The following are some common lemon tree problems. These are some of the most common lemon tree problems. They include the most severe and serious issues that affect your trees health. You need to take care of these issues because they could cause your trees death or even make them die prematurely.
Some of these problems may not kill your trees immediately but it will lead to their death later on in life if left untreated. If you do not take proper care of these issues, then you risk losing your trees.
Leaf Curl: Leaky Root Zone
Leakage from the root zone is one of the major causes of lemon tree problems. This problem occurs when water gets into the roots and makes its way through the soil and out to other parts of your trees system. When this happens, it leads to a loss in vigor and leaves. Other causes of leeching include poor drainage, excessive watering, and improper pruning.
Root Rot: Root Rot
A condition called root rot is caused by lack of oxygen in the soil around the roots. The root zone becomes infected with fungi which produce toxins that eventually destroy the plant’s structure. This disease usually affects young trees but can occur at any age depending on how long it takes for the fungus to grow and infect your plants roots.
Light Leaf Spot: Cloudy Water
Sometimes, water can contain too many minerals. The most common of these are iron and manganese. When these minerals come into contact with the leaves of your trees they form a substance called oxalic acid. This acid causes spots and lesions on your leaves that form what is known as cloudy water.
Greasy Spot: Greasy Leaves
Greasy spot causes yellow rings to develop on the leaves. This issue is caused by a fungal infection. The fungus that causes greasy spot also infects the fruit of your trees and can cause them to rot. While greasy spot doesn’t directly affect the health of your tree, it obviously still poses a problem since no one wants to pick up a lemon with rotten spots all over it.
Mildew: Plant Disease
Mildew affects all parts of the tree but is most notable on the leaves. It causes them to develop a grayish white coating which reduces the efficiency of photosynthesis. It spreads quickly so it is important to identify and treat this issue as soon as possible.
Root Knot: Root Knot Nematodes
These are microscopic creatures that attack the root system of your trees. The female nematode is larger than the male and can produce up to 2,000 eggs. The eggs then hatch and infect the roots of your trees. If left untreated, this problem could kill your lemon tree.
Scab: Scabby Appearances
Scab is a fungal disease that causes dark spots and patches on the leaves of your trees. This condition is most noticeable on young trees that are under stress.
