What causes the leaves of the yew to drop?
The yew is a shallow-rooted plant with fairly well-developed lateral roots. It has a very long history in China, and the yew has high ornamental value as well as a strong anti-cancer effect. Nowadays, quite a lot of people grow yew as a potted plant. But when caring for a yew, the yew may drop its leaves, which affects its growth. So what causes the yew to drop its leaves? Let's take a look below!
1. Improper watering
When growing a yew, watering is indispensable. However, if you water too often and in too large an amount, the soil will become waterlogged, and if the water is not drained in time, the soil will become too wet. The roots gradually rot from the water, the leaves do not get enough nutrients, and the leaves will slowly fall off. So when watering, we should decide based on the condition of the soil. If it is grown indoors, then watering about once every three weeks is enough; if outdoors, this can be shortened to about two weeks. If the soil is too wet, then drain it in time.
2. Improper fertilizing
During the growth of the yew, nutrition is of course also very important. So fertilizing work must also be done well, but when fertilizing, you must also pay attention to controlling the amount of fertilizer. Too much or too little fertilizer will have a great impact on the yew. If too little fertilizer is applied, then the leaves lack enough nutrients, such as iron, magnesium, etc., causing the yew to drop leaves, while too much fertilizer will cause fertilizer burn in the yew. Therefore, when fertilizing, we must pay attention to controlling the amount and frequency of fertilizing. It is best to mainly use fertilizer specially made for yews to ensure the normal growth of the yew.
3. No pruning for a long time
After a long period of growth, the yew will have more and more leaves. If the yew is not pruned during its growth, then the lower branches and trunk of the yew plant will grow stronger and stronger, causing excessive consumption of nutrients and the phenomenon of leaf drop. Therefore, during the growing process, we should pay attention to doing the pruning work of the yew well, and cut off the excess branches and leaves on the plant. Properly removing the terminal buds and some side branches of the plant can not only prevent the branches and leaves from consuming too many nutrients, but also promote the growth of the root system and reduce leaf drop.
4. Unsuitable light
Light is also one of the main reasons for the yew dropping its leaves. In many cases, the yew drops its leaves mostly because of unsuitable light. The yew is not suitable for growing in an environment with too strong light; too strong light can easily scorch the leaves of the yew, causing the leaves to turn yellow and wither. However, a certain amount of light must also be maintained; with insufficient light, the leaves cannot carry out photosynthesis, which will likewise cause the leaves to shrivel and fall off. Therefore, we should pay attention to controlling the light intensity well. The light should mainly be scattered light, and in summer, do a good job of shading to weaken the light intensity.
The above is a brief introduction to what causes the leaves of the yew to drop. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
