How to do with the yellow leaves of Taxus: the temperature is too low, the leaves turn yellow and fa

Taxus chinensis is a kind of landscape and functional tree species, which has the functions of anti-cancer, purification, greening and so on.

The reason analysis and treatment methods of the sick Taxus chinensis Leaves yellowing: 1. The environment mutation causes the yew leaves to turn yellow: due to the sudden change of the growth environment, the plants can not adapt well, resulting in poor plant growth state.

Solution: when transplanting or changing the growth environment of plants, we should create an environment similar to the original growth environment, and adjust it slowly to give it a growth transition period.

2. Excessive watering causes the leaves of Taxus chinensis to turn yellow (water yellow): in the potted landscape of Taxus chinensis, the tender leaves are dark yellow and dull, and the top of new shoots is withered.

Solution: the potted landscape with mild symptoms should control the amount of watering, and use a hard and blunt object to gently pick the surface soil of the basin, so that the basin soil can breathe, and move to a place where dew can be accepted every night.

3. Long term water shortage causes the leaves of Taxus chinensis to turn yellow (dry yellow): due to long-term water shortage, the leaves are dry, and the water quality is insufficient, thus turning yellow.

Solution: the watering should be done once, and the surface soil of basin soil is dry, but the middle soil is not necessarily lack of water. When watering, it can be combined with Fungicides to prevent root rot.

4. Sun exposure causes the leaves of Taxus chinensis to turn yellow (burning yellow): because the sunlight is too strong, the transpiration of plants is too strong, and the water supplement speed of root system is insufficient, resulting in the water shortage on the leaf surface of the plant, thus withering and yellowing.

Solution: put the yew back indoors and spray water on the leaves to recover.

5. Air drying causes the leaves of Taxus chinensis to turn yellow: as the potted landscape of Taxus chinensis is placed at the air outlet of the air conditioner, the water evaporation on the leaf surface of Taxus chinensis increases, causing the branches and leaves of Taxus chinensis to dehydrate rapidly, curling and withering leaves, appearing withering and drooping.

Solution: if placed in the air conditioning room, air conditioning should be carried out every day. Spray the leaves every day, keep the humidity of the leaves, and put a basin of clean water indoors.

6. The lack of sunlight causes the leaves of Taxus chinensis to turn yellow (lack of light yellow): because the photosynthetic products can not supply the root system, the root system is lack of nutrients, and leaves turn yellow and fall off.

Solution: put it on the balcony or outdoors in the morning and evening, and do it every few days.

7. The temperature is too high to cause the leaves of yew to turn yellow: because the environment temperature of yew bonsai is too high, the plant leaves are short of water and become brown.

Solution: the growth environment temperature of Taxus chinensis should not be too high. When the temperature is high, spray water mist on the leaves to keep it moist.

8. Low temperature leads to yellow leaves of Taxus chinensis: low temperature affects the transportation of nutrients inside the plant, resulting in insufficient nutrition, resulting in yellowing and abscission of leaves.

Solution: when outdoor weather changes greatly, or when it's cold, you can put yew indoors.

9. Excessive fertilization of yew results in yellowing of leaves (fat yellow): spraying fertilizer solution on the leaves of newly purchased Taxus chinensis potted landscape just sprouted, causing the tender leaves or buds of yew potted landscape to shrink and curl.

Solution: appropriate dilution of fertilizer water, or replacement of basin soil.

10. The leaves of Taxus chinensis are yellow due to long-term lack of fertilizer. The leaves of Taxus chinensis are yellow and grow slowly, and the fruit is flat and small.

Solution: appropriate fertilization, nitrogen fertilizer can promote the growth of branches and leaves of flowers and plants; phosphorus fertilizer can promote the formation of flowers and fruits; potassium fertilizer can promote the growth of stems and roots.

11. Rotten root causes yellow leaves of Taxus chinensis: root rot, stem rot and rotten roots occur in individual saplings of Taxus chinensis in rainy season.

Solution: the water in the bonsai can be properly discharged, so as to avoid the root rot caused by the lack of oxygen due to the excessive water, and the solution of 70% dixone 500-800 times can also be used.

12. Diseases and insect pests cause the leaves of Taxus chinensis to turn yellow: on the needles and twigs at the lower part of the seedlings, small brown spots first appear, gradually expand into dark brown, and finally cause the leaves and twigs to wither.

Solution: in the high temperature and drought season, individual saplings will have leaf blight and Fusarium blight. Spray 1% Bordeaux solution or 50% Emamectin 500-1000 times solution, once every two weeks. When the weather is dry, the spraying frequency can be reduced appropriately.

Healthy Taxus chinensis conservation experience: yew is a yew bonsai shade and afraid of sun, like wet afraid of waterlogging plants, so in the planting time should pay attention to watering, not too much. Some people like to pour the remaining tea water into the bonsai. Remember that this is not advisable because the tea is alkaline, while the growth environment of Taxus chinensis is acidic. Moreover, the flowerpot of Taxus chinensis should be larger, and several holes should be drilled in the basin to enhance the water permeability and air permeability of the flowerpot.
