What s going on with taro curling leaves and smaller leaves at the bottom?

There are many reasons why taro leaves are rolled. If it is caused by lack of moisture, it needs to be watered in time; If it is caused by too strong light, you need to put it in semi-shade and see light every morning and evening; If it is caused by poor air circulation, you need to put it in a spacious place indoors and open the window for ventilation every day; If it is caused by leaf spot, it is necessary to cut off the diseased branches and leaves, and spray Bordeaux liquid to prevent and control.

1. Watering moderately.

Reason: There are many varieties of arrowroot, and the demand for water is also different, if the water volume is not well controlled, it is easy to cause the leaves to roll.

Solution: For varieties with thin and large leaves of arrowroot, it is necessary to water frequently, and it can be watered once a day during the growth period. However, varieties with thicker and slender leaves have longer watering intervals, usually 3-4 times a day in summer.

At the same time, in the low temperature season, water less to keep the soil dry.

2. Shade and avoid light.

Reason: Arrowroot does not have a very high demand for light, and it is easy to be burned after being exposed to strong light, resulting in curling leaves.

Solution: Moderate shade during its growing season. Especially in the summer when the temperature is high, avoid exposure to the sun. You can place it in a semi-shaded place to receive scattered light. But you can see light every morning and evening to prevent stunting, thinning of leaves, and so on.

3. Strengthen ventilation.

Cause: Poor air circulation can cause arrowroot to breathe poorly, which makes it grow poorly, causing the leaves to curl.

Solution: Put the arrowroot in a well-ventilated place. If you breed indoors, you can put it in a spacious room, and open the windows every day to improve air circulation. Especially in environments with high humidity, air circulation can reduce the risk of bacterial growth.

Fourth, disease prevention and control.

Cause: Arrowroot is susceptible to leaf spot disease during the growth period, and the leaves of the diseased plant will dry up and curle.

Solution: Cut off the diseased branches and leaves first, and destroy them in a centralized manner to avoid the spread of germs. Then spray Bordeaux liquid, the concentration should not be too high, around the right and left.

Generally, two sprays are sufficient**. To prevent disease**, put the plants in a ventilated place and reduce watering.

It may be because of too much rain, so that the soil is full of water, the soil void becomes smaller, the plant root system lacks air, resulting in rotten roots, so that the leaves turn yellow, or it may be because of long-term rainy days, the soil and environmental humidity is too large, coupled with the high temperature after the rain, so that the plant is easily infected by pathogenic bacteria, causing the plant to also turn yellow, you can turn the soil properly, but be careful not to hurt the root system, and then spray 40% carbendazim 500-1000 times the solution, or use carbendazim to irrigate the roots.

Summary. Hello, glad for your question. Reasons for scorched edges of taro leaves:

1. Lack of light taro has a greater demand for light during the growth period, and the lack of light will make the taro leaves yellow. Therefore, during the growth period of taro, it is necessary to give more than 5 hours of sunlight every day. When the light is too strong, a shade net can be built on top of the taro to weaken the intensity of the light.

Hello, glad for your question. The reasons for the scorching edge of taro leaves: 1. Lack of light taro has a greater demand for light cavity during the growth period, and the lack of light will make taro leaves yellow.

Therefore, during the growth period of taro, it is necessary to give more than 5 hours of sunlight every day. When the light is too strong, Kewuhe builds a layer of sunshade hail net above the taro to weaken the intensity of the light.

2. Lack of nutrients, if the taro young leaves become lighter in color, yellow or light green, and the old leaves are in a normal growth state or turn from green to yellow, it may be caused by the lack of nutrients in the soil.

3. The yellowing of taro leaves may also be caused by soil waterlogging, which will lead to difficulty in root respiration and rotten roots and yellow leaves. Therefore, the amount of watering needs to be strictly controlled during the daily maintenance of the taro, which can be watered every 2 or 3 days to ensure that the soil is in a moist state. 4. Bacterial infection.

Taro is suitable for growing in a ventilated and breathable environment, if the taro growth environment is too closed, it will make a large number of germs breed, making taro leaves yellow. At this time, the diluted carbendazim solution can be sprayed on the leaves late to alleviate the problem, so that the root wilt system and the leaves can resume growth as soon as possible.

The reason why the leaves of the taro are not raised very well.

Reason 1: Insufficient water or too much watering.

Alocasia is a plant that prefers a humid growth environment, especially during the growing season, it needs enough water to ensure the nutrients needed for plant growth, so as to promote the rapid growth of plants; If the water is not enough, the growth of taro fan Zhengtou will be restricted, especially the leaves, which will not grow and will become dark after being clipped; In addition, too much watering will cause water accumulation in the potting soil, resulting in rotten roots, which in turn affects the growth of leaves, so the leaves cannot grow.

Reason 2: The soil is too sticky.

Taro is a plant that transports underground tubers, and its growing environment requires loose, fertile, well-drained soil. If the soil is too sticky, it will make the root system unable to breathe, which will affect the growth and development of the root system. In this case, the leaves do not grow.

Reason 3: The temperature is too high or too low.

The optimum temperature for taro growth is between 22-28. If the growth temperature is too high or too low, it is not conducive to the growth of the leaves, so it will also cause the taro leaves to grow very little. On the other hand, there are the light conditions.

Too little light will also affect the growth and development of taro leaves, so they can't grow.

Mosaic taro leaves are not very large** method.

First of all, water reasonably, no more, no less. Water the potting soil when it is dry, and do not water it when it is dry. Secondly, the soil should be loosened frequently, and it can also be turned over again. In short, don't let the soil be too dry and too hard. Finally, it is to maintain a balanced temperature and enough light to promote.

Summary. Hello, taro grows well when new leaves are born in the middle of each leaf.

The taro leaves are shield-shaped leaves, the leaves are broad and thick, hairless, smooth and slightly waxy, the texture is fragile, the leaf color is green, the base of the leaves is light purple, the general leaves are 50 cm 35 cm, and the large ones can reach 60 cm 50 cm. Under normal circumstances, the number of leaves is 8 9 pieces, and the number of leaves can reach 10 13 under high fertilizer conditions, but there are only 5 6 green leaves with photosynthesis, and 7 8 leaves can be maintained in high fertilizer fields. At the beginning of growth, the leaves are smaller, the petioles are shorter, and the leaves are the largest in August, and then the leaves become slower and smaller as the temperature drops, and the leaves gradually turn yellow and die in October.

The petiole is green, reticulated and hollow.

The petiole of taro is 40 to 80 cm long, erect or spreading, the lower part is swollen into a sheath, holding a stem, there is a groove in the middle, and the petiole is green, red, purple or black, which is often used as the basis for the naming of varieties. At the peak of taro growth, the petioles on fertile soil can reach more than 2 meters. The diameter of the petiole is 1, 4 cm.

The upper cross-section of the petiole is round, the lower 10 cm of the leaf is often purple, the planting density is small, the group has good light transmission, the color is dark, the density is large, and the color is light when the fertilizer and water conditions are good.

What medicine is used for taro rotten roots.

The bright rot of the taro should be sprayed with 600 times of 30% copper oxychloride suspension, or 3000 times of 72% sparrowtomycin sulfate soluble powder, 1:1:100 Bordeaux solution.

75 100 liters of pesticide solution per mu were applied, once every 10 days or so, and 2 3 times were continued to be controlled by ants.

1. Improper watering.

Jerusalem artichoke leaves are soft, which may be caused by improper watering. It needs more water during the growing season, so water it frequently to keep the soil moist. If the soil is dry for a long time, the plant cannot absorb water, and it is easy to droop and soften, or even wither and fall off.

It is recommended to rehydrate as soon as possible, and thoroughly hydrate at once. The amount of watering should be controlled, and no water should be accumulated. Water affects root respiration, and the leaves will become soft and yellow over time.

If there is a lot of moisture, ventilate and loosen the soil frequently to evaporate the water.

2. Improper lighting.

Alocasia likes light, but it can only be scattered light. If the environment is too bright and there is direct light, the plant can easily get sunburned, and the leaves will droop, soften, or even turn yellow and fall off. It should be removed as soon as possible and moved to a cool, ventilated place to promote faster recovery.

3. Soil discomfort.

It has high requirements for the soil, which should be loose and breathable, and well drained. During the maintenance period, it is generally replaced once every one or two years. All the old soil is dumped and the new nutrient soil is reconfigured.

If the soil is not changed for a long time, the soil is easy to compact, hindering the growth of plant dust preparations, and the leaves will become soft, yellow or even fall off. Pay attention to changing the soil as soon as possible, you can recover slowly.

If the old leaves below the taro swelling period need to be removed, if the old leaves are not removed in time, it will cause some nutrients to be lost to the old leaves, which will cause the taro root fruit to grow slowly, and the smaller the fruit, the more old leaves below will also cause poor ventilation, easy to breed bacteria and cause diseases, so we must remove the old leaves under the taro, so as to reduce the nutrient competition between the roots and leaves, so that the taro fruit will be larger.
