Yew bonsai leaves are yellow from bottom to top, what to do!! 200

Yew transplanted from the field to the pot, placed indoors is not in place to easily appear leaf yellowing, leaf loss and other phenomena, now some of our summary of some experience and solutions to write out for your reference:

1. Yew is a negative plant, the biological properties are suitable for indoor maintenance, but many enthusiasts plant yew will lose leaves, leaf yellow, the main reason is that yew is placed indoors, there is no natural circulation of air, for a long time in a certain environment, is not conducive to the absorption of yew sunlight, nutrients, air, and in summer, the indoor temperature changes greatly, the air conditioning has a great impact, the cold air of the air conditioner has a great impact on the evaporation of yew leaves, it is recommended that the yew bonsai is placed in the window, away from the position of the air conditioner. or placed on the balcony, there is no yellowing and falling leaves;

2. If you buy the Yunnan yew cultivated in the greenhouse, and suddenly place it indoors for ornamental bonsai, it is also very easy to yellow and fall leaves, because the greenhouse environment is a little different from the natural environment, it is recommended to buy the yew bonsai, place it on the balcony to adapt to a period of time, and then place it indoors, so that the growth cycle of yew bonsai will be long;

3. Yew bonsai is best placed under a ventilated window, so that it does not die easily, if the conditions allow, place it indoors for a period of time, and then move it to the balcony for maintenance for a period of time, so that the cycle can extend the life cycle of yew bonsai;

4. Yew bonsai watering requirements, if you use tap water to water, it is best to put tap water in precipitation for 24 hours before watering, yew bonsai does not have high water requirements for water, no need to water every day;

Pro-points.

1. Block strong light: When the light is too strong, a layer of sunshade net should be pulled to block about 60% of the light. 2. Reduce watering

When the moisture in the soil is too high, stop watering as soon as possible to allow the water to evaporate. 3. Replace the potting soil: replace the soft and permeable soil.

4. Reasonable temperature control: After low-temperature frostbite, yew should be moved to a warm environment.

1. Block strong light

Yew is shade-tolerant, and has little need for light during the growth period, if it is placed in direct light for a long time, the leaves are easy to be sunburned, resulting in a large area of yellowing, at this time, the yew should be moved to a cool place to strengthen air circulation.

2. Reduce watering

Yew drought tolerance is strong, afraid of waterlogging, excessive watering during the growth period, there will be root phenomenon, so that the branches and leaves are yellow in a large area, at this time you need to stop the water as soon as possible, let the water evaporate, when the yew is maintained in the later stage, it is necessary to water in accordance with the method of seeing dry and wet.

3. Replace the potting soil

Yew has certain requirements for the soil, pot maintenance to change the soil regularly, every 1-2 years to change the soil, if the soil is compacted, it will hinder the root respiration, so that the yew branches and leaves appear yellow and withered.

4. Reasonable temperature control

Yew leaves large area yellowing and dryness may be caused by too low temperature, the plant likes a warm environment, not cold-tolerant, if it is in low temperature for a long time after winter, it will be frostbitten, you need to move the yew to a warm place, the temperature is controlled at about 10.

The appearance of a large area of yellow leaves and dead branches of yew may be caused by overwatering, so it is necessary to remove the pot and prune the roots and re-cultivate. It can also be caused by too much light, in which case a shade net needs to be built above the yew to weaken the light intensity. It may also be caused by soil compaction, so it is necessary to change the soil as soon as possible.

It may also be caused by low-temperature frostbite, which needs to be transferred to a warm environment for maintenance, and the room temperature should be controlled at about 10 side by side.

The solution to the large area of yellow leaf dead branches of yew.

Yew appears a large area of yellow leaves and dead branches may be caused by excessive watering, yew drought tolerance is strong, but waterlogging tolerance is poor, if the yew is frequently watered during the breeding period, it can not absorb water, there will be yellow leaves, at this time the yew needs to be depotted and pruned off rotten roots and yellow leaves, when watering in the later stage, it is found that the soil is dry and white after proper watering and moisturizing.

Yew appears a large area of yellow branches and dead branches may also be caused by too strong light, yew in the growth period of light demand is not large, has a certain negative resistance, if the yew is placed in strong light for a long time to maintain, its leaves are easy to be sunburned, yellowing conditions, at this time the yew needs to be transferred to a ventilated and cool environment as soon as possible to maintain, and prune off the yellowed leaves.

Yew appears a large area of yellow leaves, may also be caused by the soil is too compacted, so in the process of cultivating yew, need to change the pot every 1 2 years, if there is no change of soil and potting for a long time, the soil compaction is serious, it will hinder the respiration of the root system, it is easy to make the yew leaves appear yellow and dry, at this time it is necessary to loosen the soil in time, and replace it with loose and breathable new soil.

Yew leaves large area yellowing and drying can also be caused by too low temperature, yew is suitable for growing in a warm environment, if the temperature can not be reasonably controlled after winter, long-term growth in a low temperature environment, yew leaves will appear yellowing, at this time need to increase the room temperature as soon as possible, transfer the yew to a warm environment for maintenance, and control the room temperature at about 10.

Last month in Dali bought a pot of yew bonsai, I heard that now this thing is very precious, are about to become a giant panda, take it back and put it in the living room, look very comfortable, but it didn't take long for the yew to start withering leaves, the leaves turned yellow, falling leaves, what can I do? The yew leaves were a little hard when I bought them before, but now the yew leaves are soft. If you buy a yew bonsai cultivated in a greenhouse, suddenly placed indoors for ornamental bonsai, it is also very easy to yellow leaves, the reason for falling leaves, because the greenhouse environment is a little different from the natural environment, it is recommended to buy back yew bonsai, place it on the balcony to adapt to a period of time, and then place it indoors, so that the yew bonsai growth cycle will be long;

1.

Watering Water loss makes it easy for leaves to droop.

1. "Newly purchased bonsai maintenance" It is best to spray the new high-lipid film on the foliar surface of the newly purchased yew bonsai every three or four days, generally before ten o'clock in the morning, or at about four o'clock in the afternoon, after three to four consecutive sprays, gradually reduce to about once a month.

2. "Light requirements" Yew is a shade-loving plant and is suitable for indoor placement, but it should be noted that it should be properly shaded in summer and should not be placed in a room with light.

3. "Soil selection" The soil quality of yew planting should be loose, rich in humus, fertile, and slightly acidic soil (between pH=5).

4. "Water requirements" The surface of the potting soil is slightly yellowish-white, the leaves are slightly curled, and the potting soil does not need to be watered, as long as the leaves are sprayed. When the soil in the pot is whitish, the potting soil should be watered. Pay attention to watering at one time to make the potting soil fully absorb enough water.

5. "Soil fertility" The three elements of plant growth: nitrogen, phosphorus and potassium fertilizer, nitrogen fertilizer can promote the growth of flowers and plants, branches and leaves;

6. "Bonsai trimming" If the dry yellow leaves in the lower part of the bonsai fall off seriously, it may be that the lower branches are too dense, and you need to prune off a few branches of the lower overdense branches. In order to reduce the excessive consumption of nutrients by branches and leaves, and restore the growth of the root system. Apply a callus antiseptic film to the trim mouth to promote wound healing.

7. "Pest control" In high temperature and dry season, leaf blight and red blight will occur in individual yew saplings, and a variety of targeted drugs can be sprayed for rotation and controlled, and new high-lipid film can be added to enhance the control effect.

Yew is especially afraid of direct sunlight, shading, and less watering. Never use rooting powder.

You have two big mistakes: 1, what is the use of soil with water, he doesn't like water, and he only pays it once every five days or a week.

2, he likes yin You put him in the sun in very hot weather, ruthless!

Depending on what breed you are, if you want to relieve the Northeast or Mandia for a few days, the vitality is very strong, quickly cover him.

If the yew is very dry, there is basically no way to save it. There could be two reasons for this:

1. When you transplant yew, the temperature is high, and the soil balls scatter during transplantation, causing root injuries and affecting the normal absorption function of the plant.

2 Another possibility is that after your transplant, you will water it frequently. Excessive water affects the absorption of oxygen by the roots of the plant, resulting in yew root rot.

Yew transplantation should be done in September-October and March-April, other times are not suitable for transplanting. After transplantation, yew should be watered thoroughly at one time, and only maintain a certain humidity in the future, and do not water it often. Otherwise, the yew will rot and die due to excessive water.

Yew leaves are yellow and branches are dry? As long as you maintain it like this, the new shoots will swish and grow.

Yew bonsai maintenance.

1. Try not to spray fertilizer on the foliar surface of the newly purchased yew bonsai when it has just germinated new shoots, because at this time the yew bonsai has not really survived or the leaves are too tender, if fertilization at this time will make the leaves or shoots shrink and curl. In order to affect the normal germination of new roots, the amount of water sprayed on the foliar surface should not be too much, and the water droplets that can be seen on the leaf surface but do not drip down. Spray two hours before dark in the afternoon, and do not leave water droplets at night (especially when the amount is large), otherwise it will affect the normal growth of young leaves or the leaves will turn yellow, affecting the healthy growth of plants.

The reverse side of the leaf can be sprayed more than the front, because there is a waxy protective film on the front of the leaf, which will hinder the absorption of nutrients and water, while the back of the leaf has no waxy layer, more pores, and stronger ability to absorb water and fertilizer. So the back absorbs faster and more than the surface of the blade). Depending on the situation and temperature, once a day or two or three times a day.

Note that the room needs to be ventilated frequently.

Second, the newly purchased yew bonsai with a height of about 40 cm, due to the transplantation from the planting base to the pot will cause damage to a part of the root system, so that the nutrient supply between the root and the branches and leaves is unbalanced, especially those bonsai with lush branches and leaves, the evaporation of the leaf surface is greater than the absorption of the root system, and the top leaves are curled and dried under the condition that the potting soil is kept moist, so it is best to prune the branches and leaves properly to reduce the water of the branches and leaves. Excessive consumption of nutrients restores the growth of the root system as soon as possible, and at the same time, it is necessary to control watering and keep the potting soil slightly dry, so as to facilitate the growth of roots as soon as possible and accelerate the return to normal ** nutrients. At the same time, yew has a strong germination ability, especially the strong growth ability of new branches, which is very resistant to pruning, and will germinate new branches and new leaves soon after survival.

If necessary, plant rooting or rooting agent can be used to water the potting soil every seven days or so, three or four times in a row (use better quality products and do not use too much water), so that the root system can grow quickly and healthily. The supply balance between roots and leaves should be restored as soon as possible, so that yew can grow well.

Your current temperature and climate and how often you water it tell me whether the potting soil is very wet and what the leaves reflect, it is better to have a picture.

It must be the cold weather or the lack of water.
