The sudden change of growth environment will lead to the inability of Taxus chinensis to adapt at once, resulting in the poor growth of plants and the phenomenon of yellow leaves.
In the process of transplanting Taxus, we need to create an environment similar to the original environment, and then adjust it slowly. When the growth environment suddenly changes, it is the same, adjust slowly
In the process of cultivation, too much water will cause the leaves of Taxus chinensis to be dull and the top center of new shoots to wilt. Long time water shortage will lead to dry leaves, lack of water, yellow phenomenon.
When the situation is not very serious, it is necessary to control the amount of water. Use a shovel to gently loosen the soil on the surface of the basin to let the soil breathe. Move to a place with dew every night. When the situation is serious, change the soil directly. In the process of watering, we should take the principle of not drying, not pouring, then pouring thoroughly. We should pay attention to the surface of basin soil is dry, but the middle soil is not necessarily short of water. When watering, we can use some anti rotten agent
In summer, when Taxus chinensis is exposed to direct sunlight, it will cause the plant transpiration to be too strong, and the root system can not keep up with the speed of water replenishment, resulting in the water shortage of plant leaves and wilting and yellowness.
Put the yew indoors, spray water on the leaves, and it will recover after a while.
Yew is not suitable for the air-conditioning outlet, which will lead to the increase of water evaporation on the leaf surface of yew, resulting in rapid dehydration of the branches and leaves of yew, the leaf curl and dry, wilting and drooping.
If air conditioning is on indoors, spray water on the leaves of Taxus chinensis, keep the humidity on the leaves, and put a basin of water in the room.
Insufficient light. Photosynthesis is weak, photosynthetic products can not supply the root system, is the root system lack of nutrients leading to yellow leaves, leaves.
Sooner or later, put it on the balcony or outdoors, and do it every few days.
The environmental temperature of Taxus chinensis is too high, which will lead to water shortage and scorch yellow phenomenon. Too low temperature will affect the internal nutrition transportation of plants, resulting in insufficient nutrition, making the leaves yellow.
When the temperature is too high, spray water mist on the leaves of Taxus to keep them moist. When the outdoor weather changes greatly, we should pay attention to the prevention of cold and warm Taxus.
The newly purchased Taxus chinensis can't spray fertilizer on the newly sprouted leaves, which will cause the young leaves or buds to shrink and curl. Long term lack of fertilizer will lead to yellow leaves and slow growth.
When too much fertilizer is applied, it is necessary to dilute the fertilizer water properly or change the basin soil. When the long-term lack of fertilizer, to apply nitrogen, phosphorus, potassium
Diseases and insect pests will cause small brown spots on the needles and twigs at the lower part of the seedlings, gradually expand into dark brown, and finally cause the leaves to die.
When appear leaf blight and red blight, want to undertake treatment, use Bordeaux fluid to prevent or control or abacteria..
