Why are the leaves of lilies turning yellow?

1. Too much watering

Reason: Lilies do not like a humid environment. Too much watering will cause the bulbs to have difficulty breathing, resulting in yellow leaves.

Solution: If there is water accumulation in the flowerpot, drain it immediately. It is also necessary to loosen the soil appropriately to accelerate the evaporation of moisture in the soil, or replace it with dry soil and replant. Usually pay attention to control the amount of water and keep the soil slightly moist. In addition, you can place the flower pots in a ventilated place, and good air circulation can also alleviate the moisture problem.

2. Insufficient Fertilization

Cause: Due to lack of nutrients, the lily grows poorly, causing the leaves to turn yellow.

Solution: Fertilization should be changed as the lily grows. Apply compound fertilizer 2-3 times a month during the growing season. Potassium dihydrogen phosphate can also be applied before flowering. Appropriate topdressing should also be applied after flowering to provide nutrients for the bulbs. Do not fertilize too concentratedly, otherwise it will damage the bulbs and affect their development.

3. Soil compaction

Reason: Long-term fertilization can easily cause the soil to become compacted, making it impossible for water to penetrate into the roots, leading to yellow leaves.

Solution: After the lily bulbs up, pour out the original potting soil and replace it with new soil when planting in winter. If the plant does not form a ball, you need to loosen the soil regularly, and be careful not to damage the bulb when loosening the soil.

4. Pest and disease damage

Cause: Sap-sucking pests and some diseases can cause poor growth, which can lead to yellow leaves.

Solution: If disease is found, the diseased branches and leaves should be cut off and burned to prevent the spread of bacteria, and spray pesticides for treatment. For pests, if the number is small, they can be removed manually, but if the number is large, they need to be sprayed with pesticides to eliminate them.
