How to deal with the yellowing of yew leaves

How to deal with the yellow leaves of Taxus chinensis? Taxus chinensis is a tenacious plant. Many people like farming, but sometimes they find that the leaves turn yellow and don't pay attention. Why? What should I do once this happens? Let me talk about the treatment of yellow leaves of Taxus chinensis.

How to deal with the environment of 1 1 and mutation in the yellow leaves of Taxus chinensis?

Taxus chinensis cultivated in pots, if moved to other places for cultivation, will easily lead to confusion in the growth state of Taxus chinensis, and the leaves will turn yellow and dry due to sudden changes in the growth environment of Taxus chinensis.

Solution: It's not that yew can only stay where it is, but to avoid moving here. Pay attention to methods and matters to ensure foolproof. First of all, when moving potted yew, it should be carried out in cool evening or night, and the ambient temperature at night is almost the same, which is most suitable for plants to move flowerpots. Secondly, near noon, we should take timely measures to shade and cool down, keep the temperature consistent with the in-situ culture, and slowly adjust the ambient temperature; It recovered in about 1-2 weeks.

2, high temperature exposure

In the hot weather in summer, if Taxus chinensis is exposed to the sun for a long time, it will easily lead to the acceleration of plant transpiration, which will lead to the yellow and dry leaves of Taxus chinensis.

Solution: First, cut the withered branches of Taxus chinensis slightly with scissors, water them and move them indoors for maintenance. Put the yew in a cool and ventilated place, which has astigmatism and often sprays water on the leaves. After a while, it will recover on its own.

Step 3 air dry

Indoor potted Taxus chinensis is not recommended to be maintained under air conditioning and fan blower; The air under the air outlet will be too dry for the growth of yew.

Solution: When turning on the air conditioner indoors, it is recommended to adjust the temperature to a suitable temperature; Taxus chinensis cultivated indoors can raise some hydroponic plants or put a pot of water next to it and spray water on its leaves regularly to increase humidity.

4. Improper fertilization

No matter too much or too little fertilization, it is not good for the growth of Taxus chinensis. Excessive fertilization will burn the roots of plants; On the contrary, long-term lack of fertilizer will also lead to the yellow leaves of Taxus chinensis, which is not conducive to its growth needs.

Solution: Taxus chinensis should be well controlled in fertilization and fertilized regularly; Fertilizer supply should not be too much or too little. If too much fertilizer is applied, it should be shoveled off or washed away with water in time. When there is a long-term fertilizer shortage, it is necessary to increase the number of fertilization, implement the principle of "less fertilizer and diligent application", and give priority to compound fertilizer of nitrogen, phosphorus and potassium, so that the roots of plants can absorb nutrients bit by bit and recover slowly.

5. Insufficient lighting

In the case of insufficient sunshine, the leaves of yew will also turn yellow. If it is placed in a dark and opaque corner for a long time, it is easy to cause the leaves to turn yellow, dry, fall off, and even die seriously.

Solution: potted yew is recommended to be planted on a well-ventilated balcony or outdoors. If the leaves of Taxus chinensis cultivated indoors turn yellow due to insufficient light, they can be placed outdoors or on a transparent balcony to make up the light in the morning and evening, and can be repeated every 2-3 days.

6. illness

The main diseases of Taxus are Fusarium wilt and damping-off disease. At the early stage of the disease, small brown spots will appear on the lower part and branches of the seedlings, which will gradually expand into dark brown, and finally lead to dry leaves and serious plant death.

Solution: Taxus chinensis should be treated with drugs in time at the initial stage of dry disease and bacterial blight, which can be prevented by dilution and spraying with Bordeaux solution or chlorothalonil.

How to deal with the yellowing of Taxus leaves 2 1? Taxus chinensis is an excellent potted foliage plant, which likes humidity, avoids light and bears drought. Therefore, it is not suitable for full light, and it should be shaded properly in summer, especially in July and August every year, under full light and strong light, chlorophyll in leaves is destroyed and young trees die. The best illumination time of Taxus chinensis is 7:00- 1 1:00 every morning, and the illumination time is about 4 hours, which is shorter in summer and longer in autumn and spring. However, insufficient light also affects the photosynthesis and growth of Taxus chinensis. Remember not to put it in a room with a western view, or near the air outlet of an air conditioner or a heater, otherwise the water in the yew leaves will be evaporated and it will be easy to dehydrate and dry up after breakfast.

2. Taxus likes acidic soil. It is best to use loose, fertile, water-retaining and breathable soil. In addition, when applying fertilizer, we should pay attention to applying fertilizer along the basin wall as far as possible, not near the roots of Taxus chinensis. Newly bought Taxus bonsai will generally have nutritious soil, and there is no need to fertilize it within three months. After three months, they will be fertilized every two to three months.

3. Due to the requirement of water, the cultivation of Taxus chinensis should observe the surface of basin soil. If it is slightly white in Huang Lue and the leaves are slightly curly, you don't need to water it, just spray the leaves. When the soil in the basin turns white, it should be watered, and it should be remembered that the water should be poured thoroughly at one time to make the soil fully absorb water.

4. Compared with common plants, Taxus chinensis has the characteristics of shade tolerance, low temperature tolerance, evergreen, strong stress resistance and extensive management resistance, and is more suitable for indoor display. It is very resistant to low temperatures, with temperatures as high as 40 degrees in summer and below zero in winter. Under the condition that the temperature difference between the four seasons is so great, yew can still grow well and has strong vitality. It is a typical lazy plant, which does not need frequent watering and digging, is suitable for extensive management and easy to survive, and is very suitable for fast-paced urban groups.
