What causes tea tree leaves to turn yellow and wilt?

Too much watering, diseases, and insect infestations can all cause the leaves of the tea plant to turn yellow.

The way of maintenance of tea trees.

1. Flower soil: Tea trees need to use weak acidic flower soil with good air permeability and strong drainage capacity. This ensures that the soil is permeable enough to prevent root rot.

2. Light: It needs a certain amount of light to help synthesize nutrients, but it cannot be exposed to strong light, otherwise the leaves may be sunburned. Therefore, it is best to plant it in a place with good sun conditions and proper shade in the summer.

2. Prune in time.

During the growing season, it needs to be topped 1-2 times at the right time to promote the growth of side shoots and allow it to grow more leaves. If you don't want it to bloom, cut it off when it sprouts, so that most of its nutrients can be used for foliage growth and become more lush.

The dry leaves of the tea tree are generally due to drought due to continuous high temperature weather, resulting in large areas of branches and leaves yellowing or even dying. Control methods: shallow tillage and weeding to reduce the contradiction between weeds and tea trees competing for water and fertilizer, and at the same time, through 3-5 cm shallow tillage, the pores and thin tubes on the surface of the soil can be cut off to reduce the evaporation of water in the soil; Water fertilizer frequently, flush 8-10 quintals of 20% farmhouse fertilizer per mu, and water in a ditch between the rows 20 cm from the base of the tea tree.

TeaThe yellowish dry tip of the leaves of the flowers is mainly due to the following three points.

The first is water yellowing, too much watering causes water to rot the roots, and the leaves of the plant will turn yellow and wilt if they cannot absorb nutrients.

The second is light, long-term strong direct light will cause plant leaf burns, serious water loss, insufficient light affects photosynthesis plants will also yellow leaves.

The third is improper fertilizer, excessive fertilization or application of unrotted fertilizer water will cause the leaves of the flowers to turn yellow and dry tips.

Tea flower cultivation method

1. Soil: 2. Watering:

This type of plant likes water more than normal plants, so pay attention to the amount of water you give to your plant. In spring and autumn, you can water the plants twice a day, and in the summer, when the temperature is high, you need to water the plants twice a day, in the morning and in the evening. You don't need to water the plants too many times in winter, you can water the plants once every 7-8 days.

3. Fertilization: This kind of plant produces beautiful flowers and nutrients play a great role, and the growth period of the plant can be given to it once a month to wash the fertilizer made of rice water, or you can use the special fertilizer bought back from the market.

1. Caused by pests and diseases.

Specific reasons: Affected by some pests and diseases, such as "red spiders", "leaf blight", etc., the leaves may turn yellow.

Solution: Spray special and targeted agents for different diseases and insect pests, and pay attention to light, ventilation, etc.

2. Watering too much.

Specific reasons: The yellowing of the leaves caused by watering mainly refers to too much watering, serious water accumulation, and root rot.

Solution: Suspend watering first, and then put it in a ventilated and cool place for a period of time. When you're almost recovered, resume watering slowly and don't accumulate water.

3. The soil is alkaline.

Specific reasons: Camellia prefers acidic soil, and the alkaline soil can easily cause the leaves to turn yellow.

Solution: Regularly change the potting soil for the plants in exchange for acidic soil, and pay attention to the nutrients it contains.

4. Lack of nitrogen.

Specific reason: When the plant is in a state of growth, if there is a lack of nitrogen, the leaves may turn yellow.

Solution: This element needs to be supplemented, such as bean cake water, etc. In addition, some ferrous sulfate can also be added.

5. Normal phenomenon.

Specific reason: The leaves of camellia generally do not fall off in a short time, but there is also the phenomenon of leaf change. At this stage, the yellowing of the leaves is a normal metabolic phenomenon.

Solution: In this case, there is no need to take any special measures, just normal maintenance.

Answer: The tip of the camellia leaf is yellow and dry, which may be caused by soil compaction, and it needs to be cultivated in time. It may also be caused by a lack of light, and the camellia needs to be transferred to a ventilated and cool place for astigmatism. It may also be caused by overwatering, and the camellia needs to be transferred to a ventilated place for maintenance to speed up the evaporation of water.

Tea leaves are yellowing because.

1. Fresh tea leaves: because of the long light time, the anthocyanins accumulate too much, and they appear purple-red; The buds of the tea will be green and yellowish, or the leaf color of special varieties of tea leaves will be yellowish and other reasons.

2. Finished tea: The leaves of the maple tree are also green during the growth period, and they will turn red in autumn; The leaves of poplar trees are also green, and they also turn yellow and wither after falling leaves. This is the life state of the leaves, and the ecological substances inside the leaves change and thus change the color.

The same goes for tea trees, the leaves are green during the growing season. If the changes in ecological substances are artificially controlled, that is, the production process of tea, the leaves of the tea tree will also become different colors, so there is a green leaf bottom for green tea, a reddish-brown leaf bottom for black tea, a red edge on the green leaves of oolong tea, a white tea leaf on the brown bottom, a yellow tea leaf with a slightly green bottom, and a dark brown tea with black tea.

There is a possibility of excessive water or fertilizer, and tea plants are suitable for growing in acidic soils, which require a certain amount of water but the roots cannot breathe if there is too much. Place the plants in a ventilated place and control the amount of water and fertilizer.

The yellowing of the leaves of the tea leaves may be caused by a lack of nutrients. Strengthen water and fertilizer management, pest and disease control, and supplement trace elements.

Watering too much or too little camellia on weekdays will have an impact on the growth of camellia, and more or less will easily cause leaf yellowing and falling off;

If the potting soil is too dry, the leaves are easy to curl, wilt and yellow;

If the potting soil is too wet, it is easy to cause root rot and yellow leaves, and in severe cases, the whole plant will die.

What to do first of all, the watering of camellia on weekdays must control the amount of watering and watering frequency, camellia in the spring and summer growth period, the temperature rises, the water demand increases, generally watering once every 10 days, and the high temperature in summer should be watered once in the morning and evening.

Why are camellia leaves yellow and dry? Figure it out in 1 and a half minutes, and cure it in a few tricks.

Diseases, lack of fertilizer, lack of water, etc. can all cause the leaves of the tea plant to turn yellow.

The way of maintenance of tea trees.

Environment: Try to do a good job of shading at noon in the hot season in summer, and increase the light appropriately in autumn and winter.

Soil: Soil should be well-drained and preferably slightly acidic, sandy loam soil and clay loam.

Moisture: The air humidity is required to be sufficient, and the potting soil should be kept slightly moist.

Temperature: The ideal wintering temperature should be around 5 degrees.

Fertilization: Fertile leaf water-soluble fertilizer can be applied during the growth period to promote its normal growth.

The wilting of camellia leaves is due to the fact that there is no way to carry out good sunlight, he has no way to photosynthesize and secrete chlorophyll, so the leaves will turn yellow and wilt.

It may be because of the lack of certain trace elements, you can add some nutrient solution to the camellia drops. Or plant it in some more fertile soil.
