Why Is Lemon Tree Losing Leaves

Lemon trees are a beloved plant for many gardeners, valued for their beautiful leaves, fragrant scent, and tasty fruit. Unfortunately, lemon tree owners sometimes experience problems when their trees start losing leaves. This can be a concerning situation, as it can lead to the tree being unhealthy and unproductive. In this article, I will discuss why lemon trees may be losing leaves and what can be done to fix the issue.

The most common cause of lemon tree leaf loss is a disorder called chlorosis. Chlorosis occurs when there is a deficiency of chlorophyll in the plant, which is necessary for the production of necessary sugars. If the leaves appear yellowish, or if there are spots or dead patches on the leaves, then this is most likely the cause. Other potential causes of leaf loss include inadequate nutrition, infestation of pest or fungus, excessive watering, or extremes in temperature.

In order to treat the problem, it is important to determine what is causing it. If the environment is too hot or too cold, then it is necessary to adjust the temperature range to a more suitable level. If the tree isn’t getting enough nutrients, then fertilizing can help. By providing a balanced fertilizer, the tree can get the right amount of essential minerals and nutrients. If there is a pest or fungus infestation, then the affected areas should be treated with the appropriate medicine or spraying.

Overwatering is also an issue that can cause a lemon tree to lose its leaves. Too much water can cause the roots to drown and the leaves to drop off. In order to obtain the right amount of water, it is essential to know the particular needs of the species and the environment in which it is planted. Careful monitoring of the soil moisture can also help to prevent overwatering.

Finally, ensuring that the tree has adequate sunlight is important for a healthy lemon tree. Taking the time to ensure adequate care will ensure that the lemon tree remains healthy, productive and beautiful. With proper care and attention, the leaves of a lemon tree will remain healthy for many years.


In addition to climate and nutrient maintenance, pruning is another important step for keeping a lemon tree healthy. Pruning shapes the tree, maintaining its health and vigor, as well as its ability to produce healthy fruit. Pruning is also important for removing dead or damaged leaves, branches and stems. An excessive amount of dead material can inhibit the growth of new healthy leaves. Depending on the particular needs of the tree, regular pruning can be helpful.

Pest Control

As with any outdoor plant, pests can be a problem for lemon trees. Common pests to watch out for include aphids, spider mites, and scale insects. The application of appropriate pest control methods, such as insecticidal soaps, oils and sprays, can help keep these pests under control. Keeping an eye out for other pest activity can also be beneficial, as certain types of worms and caterpillars can also feed on the leaves.

Fungal Prevention

Fungal diseases can be a serious problem for lemon trees, and can be especially hard to eradicate. Common fungal diseases include anthracnose, rust and powdery mildew. Prevention is key here, and keeping the tree healthy with regular nutrition and maintenance will go a long way. Pruning dead or diseased branches, thinning the canopy and raking up any fallen leaves can also help keep fungal problems away.


Lemon trees can be a source of great joy in the garden, giving their owners both the pleasure of beauty with their leaves, and the reward of delicious fruit. That being said, sometimes problems may arise and leaves may start dropping off. By understanding why this might be happening and taking appropriate preventative action, lemon tree owners can ensure their trees produce healthy leaves and delicious fruit for many years to come.
