Why Are Lily Leaves Turning Yellow? Find the Cause and Fix It Easily
The lily, also known as "Shandan" and "Zhongting", is a perennial herbaceous plant in the lily family. It is distributed throughout China, and lilies have extremely high ornamental value as well as considerable nutritional and medicinal value, making them a flower that many people love very much. However, when growing lilies, the leaves often turn yellow. So what causes yellow leaves on lilies? Below, the editor will give you a brief introduction. Let's take a look together!
1. Improper watering
Lilies like to grow in a slightly dry environment and have extremely poor tolerance to waterlogging. If they grow in an overly moist environment for a long time, the lily bulbs will rot and the plant may even die. Therefore, if you water too much, it can very easily cause the leaves to turn yellow. However, although lilies like to grow in a slightly dry environment, they should not go without watering for a long time either. So when watering, we should follow the principle of letting the soil dry out and then watering thoroughly, and never allow water to accumulate in the soil, so as to ensure normal growth of the lily. This avoids yellowing leaves caused by overwatering.
2. Improper fertilizing
Improper fertilizing is also one cause of yellow leaves on lilies. It is not only overfertilizing that causes root rot and leads to yellowing leaves; insufficient fertilizing can also cause yellow leaves due to a lack of nutrients. In particular, if there is an iron deficiency, lilies are very prone to iron-deficiency yellowing of the leaves. So we should fertilize scientifically, not overfertilize, and follow the principle of applying more frequently but in small amounts. If too much fertilizer is applied, water promptly to flush the fertilizer out. If it is iron-deficiency yellowing, then appropriately supplement some iron, such as ferrous sulfate solution. For regular topdressing, a compound fertilizer can be used as the main choice.
3. Soil compaction
The growth of lilies is closely tied to the soil. When growing lilies, because of the lily's growth and long-term watering, the soil can easily become compacted after a period of time. Once the soil is compacted, its permeability is rather poor, which is very unfavorable for the growth of lily roots. Moreover, compacted soil has fewer nutrients, and if the plant stays in compacted soil for a long time, it is very prone to yellow leaves and various other adverse conditions. So we should regularly cultivate and loosen the soil to break up soil compaction. If growing in flower pots, then change the soil regularly to ensure normal growth of the lily and improve the flowering rate and ornamental value.
4. Damage from pests and diseases
In addition to the above three factors, yellow leaves on lilies may also be caused by pests and diseases. After yellow leaves appear on a lily, if it is not caused by the above three reasons, then it is very likely caused by pests and diseases. At this time, we should promptly identify exactly which pest or disease it is, then take corresponding measures and treat the specific cause. However, the main thing is still prevention, and management should be strengthened, especially the management of water, fertilizer and soil, as these are the key to ensuring normal growth of lilies. Everyone must pay close attention to this.
The above is a brief introduction to what causes yellow leaves on lilies. That is all for today's introduction. This article is for reference only, and we hope it can help you!
