What is the reason why the leaves of potted lemon turn yellow and fall off?

Nowadays, many people like to grow lemons in potted plants at home. Although the lemon trees we usually see are mature large plants, in fact, even small lemon seedlings , with proper care, can thrive and bear fruit in a potted environment in just two years or so. But if the flowers are not well taken care of, the lemon tree will also turn yellow and drop leaves. Let’s learn below why the leaves of potted lemons turn yellow and drop leaves.

1. Adaptation after repotting

After a newly purchased lemon tree is repotted, it may experience leaf drop due to root damage and environmental changes. This is a normal adaptation process. In this case, prune the branches appropriately to reduce nutrient consumption, remove weak branches, retain strong branches, and pay attention to moisturizing, and water thoroughly when the soil is half dry. Make sure the soil is breathable and water-permeable, and place it in a well-ventilated area. Spray water regularly to help the plant absorb water and promote rapid recovery of root growth within 1 to 2 months. If the lemon tree blooms after repotting, it is recommended to cut off the flowers and give priority to root care.

2. Indoor environment issues

If a lemon tree begins to drop leaves while being grown indoors, it could be due to poor ventilation or waterlogging in the soil, leading to root rot. At this time, you need to wash the roots and change the pots, remove the soil from the roots, and check and cut off rotten roots. Soak the roots in rooting liquid and carbendazim solution for half an hour to an hour, then replace the soil with new soil to help the lemon tree reroot.

3. Indoor maintenance points

Caring for an indoor potted lemon tree is relatively simple. Choose a low pot with good air permeability, such as a clay pot, and add particles such as river sand to the soil to enhance air permeability. Place the plant in a well-ventilated, brightly lit area, avoiding dark conditions. When watering, wait until the soil surface is dry to a depth of one or two centimeters before watering thoroughly. Apply fertilizer regularly and in appropriate amounts. Beginners can use multi-element fertilizers . During the flowering period, potassium dihydrogen phosphate can be supplemented to promote flowering and fruit setting.

4. Winter care

If the indoor temperature drops below 50 degrees Fahrenheit in winter, your lemon tree may experience leaf drop. At this time, keep the soil in the pot moist and ensure sufficient light to help the lemon tree safely through its dormant period. When temperatures warm up in the spring, the lemon tree will resume growth, put on new leaves and bloom.

In conclusion, potted lemon trees are an increasingly popular household plant, but they may sometimes have issues with leaf drop. With these maintenance measures, your lemon tree can grow healthily and bear fruit even in an indoor environment.
