What if the leaves of asparagus turn yellow? Causes and solutions

Asparagus is a perennial evergreen vine ornamental plant, famous ornamental plant, asparagus is a kind of ornamental green plant with high ornamental value. It can clean the air, kill bacteria and regulate the indoor air when planted indoors. In the cultivation of asparagus, the leaves yellowed or even dried up and fell off how to do?

Yellowing of leaves caused by too much light

Asparagus likes semi-shade, avoid strong light, especially in summer to avoid direct sunlight, otherwise it will cause branches and leaves withered and yellow. The flowerpot should be moved to a cool place and water is often sprayed on the branches and leaves to increase air humidity.

Yellowing of leaves caused by improper watering

Asparagus likes to be moist but afraid of waterlogging, so it should keep the basin soil dry and wet, and generally water the topsoil to make it moist. More water is easy to rot roots, less water is easy to dry tip, in the dry season should be more to spray water to the leaves.

Yellowing of leaves caused by improper fertilization

If the application of topdressing is too thick or immature fertilizer is applied, it is easy to cause "root burning", resulting in leaf drying and shedding. On the contrary, if the potted soil is barren, the leaves will turn yellow due to lack of nutrients.

Yellowing of leaves caused by poor winter management

Asparagus likes to be warm and sunny in winter. In winter, if you put it in a place where no light can be seen for a long time, poor ventilation or cold, it is easy to cause withered and yellow leaves. Generally, the room temperature should be no less than 12 ℃, and it should be placed near the south window, and watering should be controlled properly.

Yellowing of leaves caused by poisoning

Asparagus is afraid of smoke and dust, and if it encounters poisonous gases, its branches and leaves are prone to yellowing. In addition, if the plant is too large, the flowerpot is too small or damaged by insect pests such as shell insects, it will also cause branches and leaves to turn yellow, so the pot should be changed and controlled in time.

Yellowing of leaves caused by diseases and insect pests

Once asparagus is infected with shell insects and other pests, it will also cause withered and yellow branches and leaves, so it should be controlled in time.

If asparagus does not grow luxuriantly, it should be fertilized. Here is a local way to pour white sugar water on asparagus, which can also increase nutrition. Pouring asparagus with 5% white sugar water every 20 days can make it grow luxuriantly.

What to do about the yellowing of asparagus leaves? the causes and solutions of yellowing asparagus leaves

The small branches of asparagus are many and smooth, and the leafy branches are distributed in flocculent clusters, floating like feathers, and the strength of stems and leaves shows the combination of strength and flexibility. Asparagus likes to grow in a warm and humid environment, but it is not resistant to cold and drought and needs climate control and watering, so it is suitable for growing indoors. What about the yellowing leaves of asparagus? The following is to introduce the causes and solutions of the yellowing of asparagus leaves.

Growth environment of asparagus

Asparagus likes warm, humid and semi-overcast ventilated environment, can't bear cold and drought in winter, can't pour too much water, root will rot, and avoid direct sunlight in summer. It is better to cultivate loose, fertile and well-drained sandy loam rich in humus. It is suitable to keep the room temperature between 12-18 ℃, ventilation and heat dissipation when it is more than 20 ℃, the suitable temperature for growth is 15-25 ℃, and the overwintering temperature is 5 ℃. Born in the mountains, but also cultivated in the garden.

Causes of yellowing of asparagus leaves and its solution

Watering reason

Everyone knows that asparagus likes a wet environment, but this does not mean that asparagus should be watered all the time, keeping the pot soil dry and wet, and watering it thoroughly is the right way to water asparagus.

Solution.

If there is too much watering, you can not water temporarily, but only spray water to the leaves to moisturize asparagus.

The cause of strong light

Asparagus is a semi-negative plant, it is conceivable that if placed in strong light, it will certainly burn asparagus, withered and yellow branches and leaves.

Solution method

Move the flowerpot to a cool place, and spray more water to the branches and leaves to increase humidity, water evaporation will take away a certain amount of heat, can cool asparagus.

Temperature reason

If it is in a low environment for a long time, it will lead to asparagus frostbite, asparagus frostbite and slow metabolism, which will cause leaves to turn yellow.

Solution.

The solution is to keep asparagus in an environment of about 15 degrees, and can be irradiated with appropriate astigmatism and weak light.

Fertilizer cause

Too much or too little fertilizer will lead to some discomfort of asparagus, if too much fertilizer will cause burning seedlings, if too little fertilizer will lead to subsequent undernutrition of asparagus, but also cause leaves yellowing.

Solution.

If you apply too much fertilizer, it is recommended to change the pot immediately and transplant asparagus to a new environment. Or water the plant immediately and move the plant to a place with bright light and good ventilation. If there is not enough fertilizer, it is recommended to increase the amount of chemical fertilizer to provide the nutrients needed by asparagus.

Causes of diseases and insect pests

Scale insects are the most common pest in asparagus culture. after giving birth to shell insects, if left unchecked, the nutrients of asparagus will be absorbed and the leaves will turn yellow.

Solution.

When a shell worm is found, it should be wiped off with a wet cloth in time. When it is serious, you should buy it at the drugstore for prevention and control, and change the pot soil in time. When changing the pot soil, the old residual roots can be cut off to reduce nutrient consumption.

Causes of 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. In addition, such as television radiation, fire, etc., will also cause the leaves of asparagus to turn yellow.

Solution.

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. Wipe off the dust from the leaves of asparagus, or stay away from radiation items such as televisions.

Causes of poor winter management

Asparagus has its own growth temperature, generally speaking, 12-18 ℃ is the most suitable, especially in the northern winter when placed in the sunny position. If asparagus is placed in a place with poor ventilation and too low temperature for a long time in winter, it will cause the leaves to turn yellow.

Solution.

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. If the temperature can not meet the requirements, plastic film can be used to make a simple greenhouse to help asparagus through the winter.

What to do about the yellowing of asparagus leaves? causes and solutions of yellowing of asparagus leaves

The leaves of plants will turn yellow in the process of breeding, and asparagus is no exception. What about the yellow leaves of asparagus? Then Xiaoqi analyzed the causes of asparagus yellowing and effective solutions.

1. The reason for the yellowing of asparagus leaves

1, strong light exposure: asparagus culture like semi-shade, summer should not have strong direct sunlight, otherwise it will cause branches and leaves withered and yellow. The solution is to move the flowerpot to a cool place and spray more water on the branches and leaves to increase humidity.

2. watering is incorrect: asparagus likes to be wet, but it is also too wet and waterlogged, so it is best to keep the basin soil dry and wet in the process of culture, generally not dry and not watered, but do not let the basin surface have too much waterlogging when watering. If there is too much watering, you can not water temporarily, but only spray water to the leaves to moisturize asparagus.

3. Improper fertilization: excessive fertilization or immature fertilizer will lead to yellowing and shedding of asparagus leaves. 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.

4. Gas poisoning: asparagus is very afraid of smoke and dust. if it is often attacked by harmful gases such as smoke and dust, the branches and leaves of asparagus will be yellowed. If this happens, the flowerpot should be moved away from the original position in time, pest. 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.

5. Winter management is not in place: asparagus culture should maintain 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.

2. Characteristics and solutions of yellowing of asparagus.

The main results are as follows: 1. The yellowing but not shedding of branchlets is mainly caused by insufficient nutrients and malnutrition in basin soil. Some are because the basin soil is hard and the vitality of the root system with poor ventilation decreases, which affects the normal growth of plants. In addition to replacing the basin with culture soil rich in organic matter in spring, the surface of the basin soil should be often loosened and attention should be paid to strengthening fertilization.

2. The withered and yellow leaf tip or shedding is mainly caused by less watering, dry basin soil, or too low relative humidity. Always keep the basin soil moist, and often spray water to the plant, preferably the same water temperature as room temperature, and place the plant in a place with high air humidity. Mixed fertilizers should be properly applied in the growing season to make the plants strong and enhance their resistance.

3. The color of the branch tip is dark yellow or yellowish green, which is caused by strong light or too much watering. It should be moved to a shaded place or a window with curtains to avoid direct exposure to strong light and be careful not to water too much.

4. The scorched and yellow branches fall off, mainly due to the strong wind attack in the hot summer season, or the root rot of the pots with stagnant water for a long time. Special attention should be paid to the prevention of thunderstorms or typhoons in summer. If the concentration of topdressing fertilizer is too strong or the application of immature fertilizer is too strong, it is easy to cause fertilizer damage, which will lead to leaf drying and shedding. Once fertilizer damage occurs, the pot should be poured out, and the fertilizer should be removed, then the soil mass should be washed with clean water and the new culture soil should be replaced.

The above is the relevant introduction of asparagus leaves yellowing how to do, in the process of breeding asparagus, we should pay attention to management, found that the yellowing characteristics of asparagus should be dealt with in time.
