Why is my lemon tree dropping leaves?

Lemon , this popular fruit , is not only known for its sour taste and rich vitamin C, but also loved for its diverse uses. Whether it's used to make tea, lemon honey, or in salads, lemons can add flavor to food. However, in the process of growing lemon trees , you may encounter some challenges such as yellowing leaves, leaf shedding, fruit dropping and other problems. Let’s learn together why lemon trees lose leaves.

1. High temperature and drought

Under high temperature and drought conditions, the amount of watering should be properly controlled to keep the soil slightly moist and avoid water accumulation. Increase the humidity of the air by spraying water. Spraying water several times a day will help the leaves absorb moisture and keep them firm. At the same time, be careful to avoid direct sunlight and use equipment such as shade nets to protect the plants and reduce water evaporation. If improper watering causes the soil to become compacted, the soil should be loosened in time to promote root respiration.

2. Too much girdling

Excessive ring cutting will cause larger wounds on the fruit trees, affecting nutrient transfer, leading to insufficient nutrients in the root system, and causing yellowing and falling of leaves. The treatment method is to disinfect the wound in time, use 30% myclobutanil suspension, and bandage it with adhesive tape. At the same time, spray foliar fertilizer in appropriate amounts to supplement nutrients and help the fruit tree resume growth.

3. Diseases, Pests and Insects

Foot rot is prone to occur in hot and rainy seasons. At this time, ventilation in the garden should be strengthened, the drainage and irrigation system should be ensured to be in good condition, and stagnant water should be removed in time. For fruit trees that have already become infected, the roots should be exposed to dry and sterilize, the rotten parts should be removed, and the wounds should be coated with metalaxyl. For insect pests such as leatherworms and longhorn beetles , spray 2000 times diluted 35% cypermethrin·thiacloprid suspension once every 7 to 10 days, and spray twice in a row.

In short, identifying the cause and prescribing the right remedy can effectively deal with the problems that lemon trees may encounter during their growth, reduce yellowing and falling leaves, and improve fruit quality and yield.
