How to remedy the withered leaves of the yew?

Many people grow yew bonsai for the first time, so they don't know the specific planting methods. How to remedy the withered leaves of yew? What if the leaves fall off?

How to remedy the withered leaves of the yew:

A: there is a serious imbalance in moisture

Taxus is resistant to drought and waterlogging, such as serious water stains, the basin soil is too wet, which will cause insufficient oxygen in the basin soil, anaerobic respiration of the roots, and then develop into alcoholism, root asphyxiation, rot, resulting in the death of the whole plant.

Solution: watering should be thoroughly watered once, dry and wet, the topsoil of basin soil is dry, but the middle soil is not necessarily short of water. Watering can be combined with medicament to prevent root rot: 1 gram of diexamethasone or 2 grams of carbendazim or active root promoter can be irrigated with water. Ferrous sulfate can also be added to irrigate, the concentration should be small, not high, according to the principle of a small number of times.

B: serious lack of light

Although Taxus is a shade-tolerant tree species, it still needs proper light to carry out normal photosynthesis. if the light is insufficient and the photosynthates are few, there will be a lack of sufficient nutrients, and the photosynthates can not be supplied to the root system. The lack of nutrients in the root system makes the leaves yellow and lose leaves, which is a way of plant self-regulation.

Solution: put it on the balcony or outdoors in the morning and evening, and the placement cycle can be carried out every few days.

C: small pots and big seedlings

The lack of nutrient supply in the basin soil results in yellowing of seedlings, dense root system at the edge of the basin, sensitivity to external temperature, root tip death, and then yellowing, withering and leaf loss of branches on the plant.

Solution: choose the shady time in the morning and evening to change the basin, the bottom hole of the large basin should be padded high, the bottom had better be padded with a layer of egg-sized pebbles to facilitate water penetration and no stagnant water, the basin soil should be planted with humus, and the right amount of ferrous sulfate should be added to mix evenly. One is to disinfect the basin soil, and the other is to supply iron for a long time to avoid the yellowing of leaves due to iron deficiency.

D: lack of nutrients

Lack of nutrients in the basin soil, soil hardening, resulting in dry leaves.

Solution: each pot with 10-20 grams of organic fertilizer, or rotten cake fertilizer, combined with loose basin soil and then watering, or mixed into water, but also combined with spraying foliar fertilizer.

What if the yew loses its leaves:

The symptoms caused by the transplanting of yew on the basin indicate that the conservation environment and measures are not appropriate.

1. In the conservation environment, because it is the first yew on the basin, it must be half-shaded and must not be exposed to the sun. Although the yew is more shady, it is not suitable to give the whole shade environment ~ and the air should be moist, slightly ventilated, and there should be no strong wind and convection. The air can also be dry, and it is best to spray water to the ground and air of the growing environment. Spray water on the plant must ensure that water does not flow into the basin soil.

2. When watering, be sure to water the topsoil after it dries, and do not keep it moist, otherwise it is not suitable for traumatic roots to search.

3. Put it in a semi-shade micro-ventilation place to maintain high air humidity, dry and wet watering the root system. When the basin soil needs to be watered, choose 500-600 times carbendazim solution instead of clear water.

All right, this is the end of the introduction of the solution to the yew leaf problem, all of you understand.

Yew leaves yellowing reason what to do about yew leaves drying up

Taxus is a kind of ornamental flower plant that many people like to cultivate at home, but in the process of breeding, it often shows symptoms of yellowing or withering leaves, what should be done at this time? In fact, there are many reasons for yellowing and drying up of yew leaves, so we should deal with the disease. Here I will specifically talk about the causes of yew leaves yellowing and what should be done about yew leaves drying up.

Yew leaves yellowing reason what to do about yew leaves drying up

1. Lack of light causes yellowing of leaves.

When the yew is in culture, if the light is insufficient, it will cause the leaves to yellowing or dry. Although the shade tolerance of this plant is very strong, it also needs the right amount of sunlight when growing. If the light is not enough, photosynthesis cannot be carried out. It will also make the leaves yellowing and withered. At this time, as long as the yew is moved to the sun sooner or later, the yellowing and drying of these leaves can be avoided.

2. Yellowing of leaves caused by water imbalance

Water imbalance is also an important cause of yellowing or drying up of yew leaves. Therefore, we should pay special attention to watering the yew at ordinary times, watering it thoroughly, but not too much, and adding some bacterial yarn or ferrous sulfate when watering, it is also of great benefit to prevent the leaves from yellowing and drying up.

3. Large potted seedlings can also cause yellowing of leaves.

When we usually cultivate yew, we should change the basin in time. If there is a large seedling in the basin, it will also make the leaves of the yew yellow or dry, because when the seedling is big and small, it is impossible to provide the necessary nutrients for the yew at all. and its root system will also extend to the edge of the flowerpot, the root tip will die, after the occurrence of this situation, the leaves of the yew will turn yellow or directly dry off.

What should be done to teach you the treatment of yew wilt?

Taxus is an ancient relict tree species left over from Quaternary glaciers, which has a history of 2.5 million years on earth. It is a national first-class protected plant, but now there is also artificial cultivation of yew, so how do the leaves of yew dry up? How to treat it?

What to do if the yew leaves are dry:

Taxus leaves dry for many reasons, we should find out the reasons to solve the symptoms, such as high temperature, high density will cause leaf drying.

Causes of dryness and solutions:

A: there is a serious imbalance in moisture

Taxus is resistant to drought and waterlogging, such as serious water stains, the basin soil is too wet, which will cause insufficient oxygen in the basin soil, anaerobic respiration of the roots, and then develop into alcoholism, root asphyxiation, rot, resulting in the death of the whole plant.

Solution:

Watering should be thoroughly watered once, dry and wet, and the topsoil of the basin soil is dry, but the middle soil is not necessarily short of water. Watering can be combined with the medicament to prevent root rot: add 1 gram of divisone to water or 2 grams of carbendazim or active root promoter to water. Ferrous sulfate can also be added to irrigate, the concentration should be small, not high, according to the principle of a small number of times.

B: serious lack of light

Although Taxus is a shade-tolerant tree species, it still needs proper light to carry out normal photosynthesis. if the light is insufficient and the photosynthates are few, there will be a lack of sufficient nutrients, and the photosynthates can not be supplied to the root system. The lack of nutrients in the root system makes the leaves yellow and lose leaves, which is a way of plant self-regulation.

Solution:

Put it on the balcony or outdoors in the morning and evening, and the placement cycle can be carried out every few days.

C: small pots and big seedlings

The lack of nutrient supply in the basin soil results in yellowing of seedlings, dense root system at the edge of the basin, sensitivity to external temperature, root tip death, and then yellowing, withering and leaf loss of branches on the plant.

Solution:

Choose the shady time in the morning and evening to change the basin, the bottom hole of the large basin should be padded high, the bottom had better be padded with a layer of egg-sized pebbles to facilitate water penetration and no stagnant water, and the basin soil should be planted with humus and mixed evenly with the right amount of ferrous sulfate. one is to disinfect the basin soil, and the other is to supply iron for a long time to avoid yellowing of leaves due to iron deficiency.

D: lack of nutrients

Lack of nutrients in the basin soil, soil hardening, resulting in dry leaves.

Solution:

Each pot with 10-20 grams of organic fertilizer, or mature cake fertilizer, combined with loose basin soil after watering, or mixed into water, can also be combined with spraying foliar fertilizer.

Foliar fertilizer: urea 0.3% + ferrous sulfate 0.3% potassium dihydrogen phosphate 0.3% + carbendazim 0.1%

Mixed fertilizer into medicine solution, foliar spraying, the cycle is seven to ten days, the rest of the time to spray water, tap water needs to be placed for 2-3 days before using surface water.

As leaf fertilizer spraying is mainly absorbed by stomata, and stomata are mainly concentrated on the back of leaves, water spraying is required to spray from leaf surface to leaf back in order to have a good absorption effect. The best spraying time is around five o'clock in the afternoon.

Treatment of Taxus wilt:

Fertilizer and water: Taxus is a negative tree species, which grows slowly, but has strong resistance and grows best in cool, humid climate and acidic soil. Like fertilizer, but it is not easy to apply more potted plants, otherwise, the leaves are dense, cover branches, dry posture, or the formation of new branches grow crazy, mess up the overall shape. Taxus is not tolerant to drought and is difficult to recover after loss of water. To keep the basin soil moist, use a matrix with good water retention on the basin.

Pruning: cut off the overdense branches, or properly remove the unnecessary leaves on the branches, so that the branches and leaves in the crown should be well proportioned.

On the basin and change the basin: the root system of the yew is more developed, slightly fleshy, do not hurt the root system when going on the basin or changing the basin, pay special attention to the basin or change the basin in the growing season. Otherwise, the survival rate will be affected. Half a month after the root system was injured, the needles yellowed and withered and died.

Sunshade: yew likes shade, avoid direct light, greenhouse should be shaded and maintained, and indoor placement can be placed in a bright place.
