The lemon trees are particular in case of light requirements. It is one of the reasons behind the Lemon Tree Leaves falling off. The lemon tree needs a good amount of sunlight that is bright and direct.

Though indirect light will also help them thrive. The light should reach the lemon tree for 5-6 hours.

The temperature drops below 20 degrees which means the lemon trees can get into cold stress and are susceptible to getting damaged. The lemon trees are hardy but the frost can affect the leaves.

The high temperature can inhibit the growth of lemon trees. It is one of the reasons behind the Lemon Tree Leaves falling off.

The leaves will start to fall if the temperature rises more than 50 to 60 degrees in summer and 60 to 90 degrees Fahrenheit in the fall and winter seasons. The high temperature can irritate the lemon tree leaves.

7. Pests and diseases

Pests like aphids, mealybugs, scales, bugs, and leaf miners can be the reason that the leaves are falling. It is one of the reasons behind the Lemon Tree Leaves falling off. The pest sucks the nutrients and sap from the plant body and hinders the movement of the food into the leaves which can lead to the drooping of leaves which will later fall from the trees.

The disease can be the reason also, caused by fungi, soil-borne pathogens, and bacteria as well. The disease affects the plant tissue with the result that the fruits’ quality decreases and the leaves start to fall. 

5 ways to revive back the lemon trees 

1. Spraying the tree regularly 

When the temperature is too high, or the soil is looking dry you can spray the lemon tree after a few hours in a day. 

2. Maintain the nutrients level in the soil 

Fertilize the soil one time a year in the spring season. Adding the slow-release fertilizer is effective.

The lemon trees can be fertilized one time every 2-3 months if the conditions are too stressful around the tree. 

3. Use good soil with good drainage

The soil that you use should have little sand content in it; this will improve the drainage of the soil.

The soil should not be soggy but moist and well-drained. The soil needs to be discarded if it is moldy. Use new and clean soil. 

4. Maintain a watering schedule, stick to it

The proper watering schedule is needed to make and make sure you stick to it. Water the lemon tree every other day when they are growing and if matured then water the trees one time every one to 2 weeks. Check the soil dryness before watering. 

5. Move the potted lemon tree to the better spot 

If the sunlight is too strong you can move the potted lemon plant to the shaded spot. The trees can also be covered if the temperatures are too low.
