Why Do Lily Leaves Turn Yellow? An Analysis of the Latest Causes
The lily is also known as the tiger lily, the middle courtyard lily, and so on. It is a perennial herbaceous plant of the Liliaceae family. It is distributed throughout our country. The lily has extremely high ornamental value and also relatively high nutritional and medicinal value, making it a flower that many people greatly love. However, when growing lilies, the lily often has yellow leaves. So what is going on with yellow leaves on lilies? Below, the editor will give everyone 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, it will cause the lily bulbs to rot, or even die. Therefore, if watered too much, it can very easily cause the leaves to turn yellow. However, although lilies like to grow in a slightly dry environment, they also cannot go without watering for a long time. Therefore, when watering, we should follow the principle of letting the soil dry and then become wet, and we must never let water accumulate in the soil, so as to ensure the normal growth of the lily. Avoid the yellow leaf phenomenon caused by excessive watering.
2. Improper fertilizing
Improper fertilizing is also one cause of yellow leaves on lilies. It is not only because excessive fertilizing causes root rot and triggers leaf yellowing, but it may also be because insufficient fertilizing leads to a lack of nutrients and causes leaf yellowing. Especially if there is a lack of iron, lilies are very prone to iron-deficiency yellow leaves. So we should fertilize scientifically and must not fertilize excessively, following 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 yellow leaves, then appropriately supplement some iron elements, such as ferrous sulfate solution, etc. For regular topdressing, compound fertilizer can be mainly used.
3. Soil compaction
The growth of lilies is closely related to the soil. When planting lilies, because of the growth of the lily and long-term watering, etc., after a period of time, the soil is prone to compaction. After the soil becomes compacted, its permeability is relatively poor, which is very unfavorable to the growth of the lily's roots. Moreover, compacted soil has fewer nutrients, and if it remains in compacted soil for a long time, it is very prone to various adverse phenomena such as yellow leaves. So we should regularly cultivate and loosen the soil to break up soil compaction. If it is grown in flower pots, then the soil should be changed regularly to ensure the 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 the yellow leaf phenomenon appears on lilies, 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 find out exactly which pests or diseases are involved, then take corresponding measures and prescribe the right remedy. However, the main thing is still to focus on prevention and strengthen management, especially the management of water, fertilizer, and soil. These are the keys to ensuring the normal growth of lilies, and everyone must pay close attention.
The above is a brief introduction to what is going on with yellow leaves on lilies. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
