Eleven causes of yellowing of asparagus leaves and their treatment

Causes of yellowing of asparagus leaves 1. Excessive watering

In the case of watering asparagus, the amount of water is too much, and the basin soil of asparagus is too wet for a long time, resulting in anoxia in the basin soil, rotting part of fibrous roots, hindering normal respiration and absorption of water and nutrients, causing asparagus leaves to turn yellow and fall off. After the injury, the young leaves turned pale yellow, and then the old leaves gradually turned yellow.

What to do

Immediately control the amount of water to asparagus, and stop fertilizing, and use small sticks or other small shovels to loosen the soil for a long time to make the soil aerate well. After being maintained in this way for a period of time, the yellow leaves of asparagus will slowly turn green and restore their former vitality.

2. Lack of water

Asparagus avoid missed watering or long-term watering half waist water (that is, wet and dry), which is easy to affect the absorption of asparagus nutrients, but also easy to cause asparagus leaf color dull and dull, asparagus leaves wilting and drooping. The first is the aging of the lower old leaves, and gradually withered and yellowed from the bottom up.

What to do

At this time, a small amount of watering is needed and carried out by spraying water, so that it can be gradually restored after it is gradually restored and then transferred to normal watering.

3. Indoor air drying

If the maintenance environment, indoor air is too dry, like the humid environment of asparagus will appear leaf tip dry or leaf edge scorched and other phenomena.

What to do

Methods such as water spraying and plastic film cover should be taken in time to increase air humidity.

4. long-term lack of fertilizer

Without applying ammonia fertilizer or changing soil for a long time, there is a lack of nitrogen and other nutrient elements in the basin soil, resulting in thin leaves and thin and yellow leaves.

What to do

It is necessary to pour the pot for asparagus in time, replace it with new loose and fertile culture soil, and then gradually apply rarefied mature liquid fertilizer or compound flower fertilizer to ensure its nutrient absorption, so that the roots and its branches and leaves can absorb nutrients and grow rapidly.

5. High temperature in summer

In summer, if you put asparagus at a high temperature and let the strong light shine directly, it is easy to cause the leaf tip and edge of young leaves of asparagus to scorch, or the leaves yellow to fall off.

What to do

It is necessary to move asparagus to a well-ventilated shady place in time, spray and water its leaves after 2 hours, and then slowly recover after a few days of shade.

6. Excessive shading

Although asparagus likes semi-shade, it can not be placed in shade or lack of light for a long time. It is easy to make the branches and leaves of asparagus turn yellow after a long time.

What to do

To ensure that asparagus has at least 5 hours of scattered light every day, it is generally best to put asparagus under the windowsill, so that asparagus can receive sufficient scattered light, which is more conducive to the growth of asparagus.

7. The winter temperature is too low

If the room temperature is too low in winter, asparagus, which is sexually fond of high temperature, is vulnerable to cold damage, which leads to the yellowing of leaves and death in severe cases. In addition, if the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are in short supply, the leaves will turn yellow.

What to do

Pay attention to timely adjustment of room temperature, take appropriate cold protection measures in winter, move asparagus to indoor maintenance, timely watering in summer, and take appropriate shade measures.

8. Excessive fertilization

If the fertilizer is too much, the new leaves will grow, and the old leaves will be scorched yellow.

What to do

Should stop fertilizing immediately, increase the amount of water, make the fertilizer flow out from the drainage hole at the bottom of the basin, or pour the basin immediately, rinse the mound with water and then plant it again into the basin.

9. The environment is not ventilated

If the application of nitrogen fertilizer to asparagus is too much, and the indoor ventilation condition is not good, and the branches and leaves of asparagus grow too luxuriantly and have not been pruned for a long time, the light of the branches and leaves of the inner chamber is insufficient and not ventilated, which is easy to cause the leaves to yellowing and falling off.

What to do

The branches and leaves of asparagus which are too dense should be fertilized reasonably and pruned to make them ventilated and transparent so as to increase photosynthesis and restore green vitality.

10. Metabolism

The growth of asparagus is metabolized all the time, and there will be the withered and yellow leaves of old death.

What to do

The yellowing of this kind of leaves is a normal phenomenon, which can be cut directly as yellow leaves and does not require special maintenance.

11. Diseases and insect pests

The leaf spot disease of asparagus caused by fungi and other bacteria is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, and the leaves are mottled with yellow and green after being infected by mosaic virus; suffering from shell insects, red spiders and other damage, the leaves will also become local yellow, and even the whole leaves will wither and fall off.

What to do

At this time, according to the corresponding diseases and insect pests, go to the horticultural shop to buy related drugs, spray control in time.

What if the leaves of asparagus turn yellow? Causes of yellowing of asparagus leaves and its solution

Asparagus is a kind of small green plant on the desk, tall and straight and fresh is the most favorite feature of everyone, but the leaves will turn yellow if there is a little carelessness in the process of planting asparagus, which is also the longest phenomenon encountered by flower friends who cultivate asparagus. What about the yellowing of asparagus leaves? In fact, there are many possible reasons for the yellowing of asparagus leaves, the most important factors are light, watering, fertilization, or asparagus poisoning and so on. The editor summarized several reasons and solutions for the yellowing of asparagus leaves. I hope it will be helpful to you.

1. The light is not comfortable. Asparagus is a kind of plant that avoids dry wind, likes semi-shade and is slightly tolerant to shade, so it is not suitable to be exposed to strong light, especially in summer, we should pay more attention to avoid direct sunlight, otherwise it will cause branches and leaves withered and yellow and even plant necrosis. The solution is also very simple: move the asparagus to a ventilated and cool place and spray some fog around the branches and leaves to increase its humidity.

2. Watering is wrong. Asparagus likes to be wet and afraid of waterlogging. When watering, we should pay great attention to the amount of water. Generally, it is appropriate for the basin soil to maintain 20% humidity, that is, the water poured into the basin quickly seeps into the soil and the soil surface does not accumulate water, so it is best not to dry or water in the planting process, and the water is watered thoroughly. If there is too much water, it is necessary to stop not watering, and spray more fog around the branches and leaves to moisturize asparagus.

3. Improper fertilization. Asparagus likes to be rich in humus, well-drained soil, can adopt the principle of multiple fertilization and a small amount of each time, and the use of mature fertilizer. If the lack of fertilizer, fertilizer is too thick or the application of immature fertilizer, will cause asparagus leaves yellowing, shedding and even withered. If it is due to improper fertilization caused by asparagus leaves yellowing, can be taken to change the basin soil to solve. It is worth noting that it is not suitable to apply fertilizer in winter low temperature period and summer high temperature period, and fertilization should be controlled after plant setting.

4. Gas poisoning. Asparagus is very afraid of smoke and dust. if it is often attacked by harmful gases such as smoke and dust, asparagus will be poisoned with yellow branches and leaves. If this happens, the flowerpot should be moved away from the original position in time, and the work of foliar sprinkler and dust removal should be increased.

5. Insect pests. Shell insects are the most common pest in asparagus culture. When shell insects are found, they should be wiped off with wet cloth strips in time. In serious cases, they should be bought at the drugstore for prevention and control, and the pot soil should be changed in time. When changing the basin soil, the old residual roots can be cut off to reduce nutrient consumption.

6. Winter management is not in place. Asparagus culture should keep it at a certain temperature, especially in the sunny position in winter. If asparagus is placed in places that lack light, poor ventilation and cold for a long time, it is easy to make the leaves of asparagus withered and yellow. The temperature of asparagus culture in winter should not be lower than 12 ℃, and it should be placed in a place with good light, and watering can be reduced appropriately.

7. Others. In addition, the reason for the yellowing of asparagus leaves may also be that asparagus culture pots are placed next to organic items such as heating bags, air conditioners and televisions, which can also cause asparagus leaves yellowing and shedding because of high radioactivity, and the stems will dry up over a long period of time, so pay attention to it when placing flowerpots in asparagus culture.

Asparagus is a relatively weak plant, and growers need to take good care of it in daily maintenance. If the leaves of asparagus turn yellow because of insufficient nutrition, you can also use a "folk prescription" to improve the nutrition of asparagus-pouring white sugar water to asparagus to ensure that your asparagus can grow very luxuriantly.

The leaf of asparagus is yellow, which not only affects the healthy growth of asparagus, but also affects the aesthetic effect of indoor furnishings and spoils the taste of the owner of the house. therefore, the editor summarizes the above reasons for the yellowing of asparagus leaves and solutions hope to exchange more planting experience with the majority of flower friends.

Solutions to the yellowing of asparagus leaves for four reasons

Asparagus is a common indoor plant, and the yellowing of asparagus leaves is one of the most common diseases of asparagus. Here are four reasons for the yellowing of asparagus leaves.

What if the leaves of asparagus turn yellow-- reason 1:

Winter management is not in place. Asparagus culture should keep it at a certain temperature, especially in the sunny position in winter. If asparagus is placed in places that lack light, poor ventilation and cold for a long time, it is easy to make the leaves of asparagus withered and yellow. The temperature of asparagus culture in winter should not be lower than 12 ℃, and it should be placed in a place with good light, and watering can be reduced appropriately.

What about the yellowing leaves of asparagus?-reason two:

Pests. Shell insects are the most common pest in asparagus culture. When shell insects are found, they should be wiped off with wet cloth strips in time. In serious cases, they should be bought at the drugstore for prevention and control, and the pot soil should be changed in time. When changing the basin soil, the old residual roots can be cut off to reduce nutrient consumption.

What about the yellowing leaves of asparagus?-reason 3:

Gas poisoning. Asparagus is very afraid of smoke layer, if often attacked by smoke and other harmful gases, asparagus will appear yellow branches and leaves poisoning phenomenon. If this happens, the flowerpot should be moved away from the original position in time, and the work of foliar sprinkler and dust removal should be increased.

What about the yellowing leaves of asparagus?-reason 4:

Improper fertilization. Excessive fertilization or application of immature fertilizer will cause asparagus leaves to yellowing and shedding. On the other hand, the nutrient of the planted pot soil is too poor, which will also lead to the yellowing of asparagus leaves. Therefore, when applying fertilizer, we should pay attention to Pushi, but the number of times is more but less, and we should use rotten fertilizer, and for the situation that has occurred, we can take to change the basin soil to solve. It is worth noting that it is not suitable to apply fertilizer in winter low temperature period and summer high temperature period.

What about the yellowing leaves of asparagus?-reason 5:

Watering is wrong. Asparagus likes to be moist, but it is not easy to get too wet. in the process of breeding, it is best to keep the basin soil dry and wet, and the soil is watered once and for all. If too much watering occurs, it can not be watered for the time being, but only spray water to the leaves to keep asparagus moist.

What about the yellowing leaves of asparagus?-reason 6:

Bright light. Asparagus is a semi-shady plant, summer should not have a strong column of direct sunlight, otherwise it will cause branches and leaves withered and yellow. So the best way is to move the flowerpot to the shade and spray more water on the branches and leaves to increase humidity.
