Why do pepper grass leaves curl leaves? Why do the leaves of red backed pepper grass be closed?

The main reasons for pepper grass leaf rolls are as follows:

1.Sun exposure: Pepper grass is a shade-loving plant, and if exposed to excessive sunlight, it can cause the leaves of pepper grass to curl. The solution is proper shading and protection from direct sunlight.

2.Reflection: The reflection of sunlight on walls and floors can also cause damage to pepper leaves.

If pepper grass is exposed to reflected light for a long time, it may cause the leaves to curl. It is recommended to block the sun after 9 a.m. and before 4 p.m. to avoid damage to the pepper grass caused by reflected light.

3.Dehydration: Pepper grass prefers a moist environment, and if it lacks water, it may cause the leaves to curl. Make sure to water in a timely manner to keep the soil moist, but also avoid overwatering.

4.Pest and disease infestation: If pepper grass is attacked by pests and diseases, such as aphids, red spiders, etc., it may cause the leaves to curl. Once pests and diseases are found, timely measures should be taken, such as spraying insecticides or taking other corresponding control measures.

5.Too high temperature: Pepper grass has high temperature requirements, and if the temperature is too high, it may cause the leaves to curl. In hot weather, it is necessary to increase the frequency of watering appropriately and take other measures to reduce the temperature, such as increasing air circulation.

The above are several causes that cause pepper grass leaves to curl and the corresponding solutions. If none of the above methods can solve the problem, it is recommended to contact a professional horticulturist or plant expert for consultation and guidance.

The leaves of pepper grass are rolled up, which has something to do with sun exposure. Direct sunlight, combined with the reflection of sunlight on the walls and floors, causes damage to the leaves of the pepper grass. After 9 a.m. and before 4 p.m., you need to block out the sun.

1.If the rotten leaves of the rotten pepper grass are yellow, it means that it is caused by bacteria.

2.It should be noted that there should be more ventilation at ordinary times, and the air circulation of the ring where the plants are located should be good.

3.Also be careful not to keep the temperature too high, otherwise the bacteria are easily contagious.

4.It may also be the rotten leaves caused by overwatering, and the large amount of water is easy to stuff the roots, so that the leaves will turn yellow, fall, rot and so on.

5.Attention should be paid to the amount of watering, and the soil must not accumulate branch water.

Nowadays, almost every household will plant some pepper trees. When the time comes, they can pick their own chili peppers and eat them. However, in the process of planting peppercorns, there are often some problems, such as pepper leaf rolls. Let's take a look at Xiong'an with you.

1. Some vegetable farmers will spray pesticides on peppercorns when they encounter difficulties. When there are insects, grass grows, or they are sick, they spray insecticide on the pepper. As a result, excessive use of pesticides has caused irreparable damage to chili peppers. One of the direct manifestations of this is the curling and shrinking of pepper leaves.

2. Sometimes, due to the hot weather, the water in the soil hall is evaporated in large quantities, resulting in the pepper can not absorb enough nutrients to maintain nutrient growth during the growth process, and the leaves will roll up, and then wilt and fall off.

3. Sichuan pepper is generally planted in summer, when the temperature is relatively high, for example, the temperature in our summer will even reach 40 degreesIt is difficult for general crops to withstand such high temperatures, such as peppercorns, which will have a large number of leaf curls.

1. Excessive use of pesticides In this case, only the curly pepper leaves can be removed, so that the normal growth of the whole pepper will not be affected.

2. Lack of water Proper watering, should pay attention to the way of small water watering. After watering, continue to observe the growth of the leaves, if it is not good, you need to analyze to find out the cause, and then take corresponding control measures.

3. The temperature is too high You can cover the pepper with a parasol or pull a shade net to avoid direct sunlight and high temperature causing leaf rolling.

4. Pests and diseases The small-scale ones in our garden can be treated manually. Currently, the fastest and most effective method for large-scale planting is to spray pesticides.

Autumn and spring can be selected for the sowing season of Zanthoxylum pepper, and autumn sowing is better in areas with severe spring drought. Spring sowing should be sown directly before and after the "spring cluster infiltration". The soil of the seedbed is required to be fertile and loose, with 2000 kg of manure and 100 kg of phosphate fertilizer per mu, deep ploughing and ridge formation, and a compartment width of 1 meter.

After sowing, cover 1 cm of soil, and the sowing amount per mu is 4-6 kg. After sowing, Zheng Xiao covered it with straw to moisturize and promote seed germination.

The leaves of the red-backed pepper grass are closed, which may be caused by low humidity, so it is necessary to sprinkle water around the plant frequently to increase the humidity of the air. If its leaves are tightly closed, it may also be caused by too much light, and it needs to be shaded in time. If the temperature is too low, the leaves will also be closed, and it is necessary to take measures to keep warm.

1. The humidity is too low

Redback pepper grass is not tolerant to waterlogging and likes to grow in dry places, but if the humidity in the air is relatively low, it will reduce water volatilization by closing the leaves, so if you want to make its leaves comfortable, you need to sprinkle water around the plant frequently to increase the humidity of the air.

2. The light is too strong

Red-backed pepper grass likes to grow in a semi-shady environment, it is not tolerant of strong light, if its leaves appear tightly closed, it is likely to be caused by too much light, this phenomenon occurs, we need to take shade measures for it in time, it is best to move it to a cool place for maintenance, so that it can return to normal.

3. The temperature is too low

Redback pepper grass likes to grow in warm environments, its optimum growing temperature is between 18-28, it is not tolerant of low temperatures, if the temperature is too low, its leaves will be closed. At this time, it is necessary to take measures to keep it warm in time, and it is best to move it to a warm place indoors for maintenance.
