Lemon bonsai is loved by many gardening enthusiasts for its unique fragrance and rich nutrition. Many bonsai enthusiasts encounter the problem of yellow leaves and flower drop during the maintenance process, which causes a lot of frustration. This article will reveal the reasons and solutions for yellow leaves and flower drop in lemon bonsai, allowing you to easily cultivate a healthy lemon bonsai.
Reasons for Yellow Leaves and Flower Drop in Lemon Bonsai1. Insufficient lighting
Lemon bonsai enjoys plenty of sunlight. If it remains in a dark environment for a long time, it can lead to yellow leaves and even leaf drop. This is because insufficient light prevents the plant from performing photosynthesis, thus affecting growth.
2. Improper watering
Lemon bonsai requires a higher amount of water, but both excessive and insufficient watering can cause yellow leaves and flower drop. Too much water can lead to root hypoxia, affecting nutrient absorption, while too little water will cause the soil to dry out and the leaves to lose water.
3. Soil issues
Soil that is too compacted or has an unsuitable pH level will affect the growth of lemon bonsai. Compacted soil can impair root respiration, leading to yellow leaves and flower drop, while soil with an unsuitable pH level will affect the plant's nutrient absorption.
4. Improper application of fertilizer
Excessive or unsuitable fertilizer application can cause the plant to absorb too many nutrients, leading to yellow leaves and flower drop. Uneven fertilization will also affect plant growth.
5. Pest and disease infestation
Lemon bonsai is prone to being attacked by pests such as aphids and red spiders, as well as diseases like leaf spot and root rot, which cause yellow leaves and flower drop.
Solutions for Yellow Leaves and Flower Drop in Lemon Bonsai1. Adjust lighting
Place the lemon bonsai in a sunny area, ensuring at least 4-6 hours of direct sunlight per day. In the case of insufficient sunlight during winter, artificial lighting devices can be used.
2. Control watering
Water the plant according to the soil's dryness, keeping the soil slightly moist, and avoid excessive or insufficient watering.
3. Improve soil
Replace the soil with one suitable for lemon bonsai growth, such as leaf mold or peat soil. Regularly loosen the soil to maintain its looseness and breathability.
4. Fertilize properly
Choose fertilizers suitable for lemon bonsai, such as organic or compound fertilizers, and apply them evenly, avoiding excess.
5. Control pests and diseases
Regularly inspect the lemon bonsai and address pests and diseases promptly. Use biological pesticides or physical methods for control.
Yellow leaves and flower drop in lemon bonsai are not unsolvable. By addressing the causes with proper care and mastering the secrets of maintaining lemon bonsai, you will be able to cultivate a lush and healthy lemon bonsai.
