Lemon tree leaf loss can be caused by a variety of factors, including growing season, pests and diseases, environmental conditions, improper maintenance, etc. Here are some of the reasons that can cause lemon trees to lose their leaves and how to fix them:
1.Growing Season:
It is normal for lemon trees to naturally shed some of their leaves in different seasons.
If only a small number of old leaves are dried up or yellowed, there is usually no need to worry too much.
2.Environmental conditions:
Lack of light: Lemon trees need plenty of sunlight for photosynthesis and growth, and if there is not enough light, it can cause the leaves to yellowing and fall off naturally.
Solution: Place the lemon tree in full sunlight, trying to choose a south- or west-facing location.
Poor temperature: Lemon trees are suitable for growing in warm environments, and too high or too low temperatures can cause leaves to fall.
Solution: Maintain a suitable temperature range, generally between 1528 degrees Celsius.
Humidity issues: Lemon trees prefer a moist environment, but either being too wet or too dry can cause leaves to fall.
Solution: Maintain the right humidity, do not let the soil become too moist, and do not over-dry. Increase the humidity of the environment by watering regularly or using a humidifier.
3.Improper maintenance:
Overwatering: Overwatering can cause damage to the lemon tree's root system, which in turn can cause yellowing and leaf drop.
Solution: Reasonably control the amount of watering, avoid stagnant water, and let the soil dry out a little and water again.
Dehydration or dryness: Overly dry soil can cause the roots to not absorb enough water and nutrients, resulting in yellowing and shedding of leaves.
Solution: Keep the soil moist to avoid over-drying, but be careful not to over-water.
4.Pests and diseases:
Fungal infections: Lemon trees can be susceptible to fungal infections such as black spot, powdery mildew, etc., which can cause the leaves to turn yellow, dry up and fall off.
Solution: Early detection and take corresponding measures, and use appropriate fungicides for prevention and control.
Pest and disease infestation: Lemon tree leaf loss can also be associated with common pests and diseases, such as spider mites, termites, etc.
Solution: Check the leaves and roots of the lemon tree to find and eliminate pests and diseases, and also use a suitable insecticide.
5.Other factors:
Malnutrition: Lack of nutrients can also cause lemon tree leaves to turn yellow, dry up, and fall off.
Solution: Provide lemon trees with balanced nutrients, which can be supplemented with necessary nutrients by fertilizing.
Bottom leaf withering: Bottom leaf withering is normal for lemon trees, and you can gently prune the fallen bottom leaves.
For the problem of lemon trees losing leaves, you can troubleshoot them according to the above reasons and take corresponding measures. If the specific cause cannot be identified, it is advisable to seek the assistance of a professional horticulturist or plant specialist in diagnosing and dealing with the problem. We hope you will be able to restore the healthy growth of your lemon trees and enjoy the fresh lemon fruits and green plant environment!
