Reasons and solutions for yellowing leaves on narcissus
Narcissus is a flower plant that many people like very much, and it is grown on a very large scale in our country. Narcissus has very high ornamental value, so it is also very popular with many people. However, when we grow narcissus, many problems often appear that affect its ornamental value. One of them is yellowing narcissus leaves. So how should yellowing narcissus leaves be handled? Below, the editor will briefly introduce this for everyone. Let's take a look!
1. Supplement nutrients
During the growing period of narcissus, the demand for nutrients is very great. If fertilizer is not applied for a long time, narcissus will develop yellow leaves due to a lack of nutrients. In particular, a lack of nutrient elements such as nitrogen fertilizer and iron fertilizer is a main cause of yellowing narcissus leaves. So when planting narcissus, we should pay attention to doing the fertilization work well. Reasonably applying some nitrogen fertilizer is very beneficial to the growth of narcissus. We should also pay attention to regularly supplementing some iron elements, such as ferrous sulfate, which can effectively reduce the yellowing of narcissus leaves.
2. Temperature control
Temperature is very important to the growth of narcissus. During the growth process of narcissus, if the temperature is unsuitable, it is very easy for narcissus to develop yellowing leaves. For example, in summer, the temperature is relatively high and the light is relatively strong, which is very unfavorable to the growth of narcissus. At the same time, the temperature should not be too low either. If the temperature is too low, it is easy to cause frost damage to narcissus and lead to yellow leaves. So we should pay attention to adjusting the temperature well according to seasonal changes. In summer, do a good job of cooling down; conversely, in summer, pay attention to cold protection and heat preservation.
3. Light management
During growth, narcissus does not have a very great demand for light, but it should not be kept in a dark, low-light environment for a long time either. Otherwise, it is also very unfavorable to the growth of narcissus. However, attention should also be paid to light intensity. Light must never be too strong, especially in the strong-light environment of summer. If the light is too strong, it is easy for the leaves to be scorched and turn yellow. So when growing narcissus, pay attention to placing it in a place with good light but without direct strong sunlight. Avoid narcissus being exposed to direct sunlight, which can cause yellowing leaves.
4. Reasonable pruning
When planting narcissus, pruning work is also very important. If it is not pruned for a long time, the leaves and branches of narcissus will become excessive, thereby reducing the internal air permeability of the plant and very easily causing the occurrence of pests and diseases. This is also very unfavorable to the growth of narcissus and can easily lead to yellowing leaves. So we should pay attention to doing the pruning work well for narcissus, avoiding excessive branches and leaves affecting the growth of narcissus, concentrating nutrients, and at the same time also improving the internal air permeability of the plant and reducing the yellowing of narcissus leaves.
The above is a brief introduction to how to deal with yellowing narcissus leaves. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
