Yellowing lemon leaves is one of the most common problems gardeners face. Yellow leaves and leaf drops are manifestations of improper plant care or infection with diseases and pests. Stay with us to learn more about the causes and how to save them.
Why are lemon tree leaves turning yellow?
Nutrient Deficiency
One of the most common reasons why lemon tree leaves turn yellow is due to a nutrient deficiency. Specifically, a lack of nitrogen, iron, or magnesium can cause the leaves to turn yellow. Nitrogen is essential for leaf growth, and a deficiency can result in yellowing leaves. Iron is needed for chlorophyll production, and a lack of iron can cause yellowing between the veins of the leaves.
Environmental Factors
Lemon tree leaves can become yellow due to environmental variables such as excessive temperatures, high winds, and frost. Hot weather can cause the leaves to wilt and turn yellow, while frost can discolor and cause the leaves to fall off. High winds can also harm the leaves, turning them yellow.
Pests and Diseases
Lemon tree leaves can sometimes become yellow due to pests and illnesses. Spider mites, aphids, and whiteflies are common pests that affect lemon plants. These pests feed on the sap of the leaves, causing yellowing, curling, and deformation. Yellowing of the foliage can also be caused by diseases such as citrus greening, citrus canker, and root rot.
