2. Treatment method: Stop watering first, then move the potted plants to a ventilated and sunny place to allow the water to evaporate quickly. You need to stop watering first, and then move the potted plants to a ventilated sunny place to allow the water to evaporate quickly.

2. Excessive fertilization

1. Reason: Lily needs fertilizer to provide nutrients for its growth. However, it cannot tolerate excessive amounts of fertilizer. If too much fertilizer is applied during cultivation, it will not have time to absorb the fertilizer, and the excess fertilizer will remain in the soil, damaging the root system and causing yellow leaves.

2. Treatment method: Stop fertilizing and then water to dilute the fertilizer and let the excess fertilizer drain out of the pot. In serious cases, cut off the rotten roots, change the pot soil, and replant.

3. Alkaline soil

1. Reason: Lily of the valley prefers deep, well-drained, fertile, slightly acidic soil. Once the soil becomes alkaline, the lily will suffer from iron deficiency, resulting in yellow leaves.

2. Treatment method: It can be solved by spraying ferrous sulfate aqueous solution (7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water).
