What is the reason for the loss of yew leaves?

Taxus mairei is a kind of shallow root plant, and its lateral root is relatively developed. Taxus has a very long history in China. Taxus has high ornamental value and strong anti-cancer effect. At present, there are still many people planting yew as a potted plant. However, when conserving the yew, the yew will lose its leaves, which will affect the growth of the yew. So why did the yew lose its leaves? Let's take a look at it.

1. Improper watering

Although watering is indispensable when planting yew. However, if there are many watering times and a large amount of water during watering, it will lead to stagnant water in the soil, and there is no timely drainage, resulting in the soil is too wet. The roots are gradually rotten by water, the leaves do not have enough nutrient stagnant water, the leaves will slowly fall. So when we are watering, we should decide according to the condition of the soil. if it is cultivated indoors, it can be watered once in about three weeks, and it can be shortened to about two weeks outdoors. If the soil is too wet, it should be drained in time.

2. Improper fertilization

Taxus in the growth process, nutrition is of course very critical. Therefore, we should also do a good job in fertilizing, but we should also pay attention to controlling the amount of fertilizer when applying fertilizer. Too much or too little fertilization will have a great impact on the yew. If there is too little fertilization, then the leaves lack enough nutrients, such as iron, magnesium, etc., resulting in the loss of leaves of the yew, while too much fertilization will lead to fertilizer damage of the yew. Therefore, when applying fertilizer, we must pay attention to control the amount of fertilizer and the number of times of fertilization, and the fertilizer had better be given priority to the special fertilizer of Taxus to ensure the normal growth of Taxus.

3. No pruning for a long time

After a long period of growth, the number of leaves of the yew will be more and more. If the yew is not pruned during its growth, the lower branches of the yew plant grow stronger and stronger, resulting in excessive nutrient consumption and leaf loss. Therefore, in the process of planting, we should pay attention to the pruning of the yew and cut off the excess branches and leaves on the plant. Proper removal of terminal buds and some lateral branches of the plant can not only avoid excessive nutrition consumption of branches and leaves, but also promote root growth and reduce leaf loss.

4. Light discomfort

Light is also a main reason for the loss of leaves of yew. Most of the time, the loss of leaves of the yew is caused by discomfort in the light. Taxus should not grow in the environment of excessive light, if the light is too strong, it is easy to burn the leaves of the yew, resulting in yellowing and withering of the leaves. However, it is also necessary to maintain a certain amount of light, lack of light, leaves can not carry out photosynthesis, but also lead to leaf shrinkage and fall. Therefore, we should pay attention to control the light intensity, give priority to scattered light, and do a good job of shading in summer to reduce the light intensity.

The above is a brief introduction to the reason why the yew leaves are lost. That's all for today's introduction. This article is for reference only. I hope it can help you all.
