Culture methods and matters needing attention of asparagus what to do if the leaves turn yellow

Asparagus leaves are very small, very good-looking, is very suitable for bonsai, now many families are raised to have asparagus, but when raised, the leaves turn yellow, what can be done? It's not pretty at all. Let's take a look at it with the Women's Network:

Culture methods of asparagus:

1. Selection of flowerpots for asparagus culture

(1) flowerpot requirements: muddy flowerpots, plastic pots, porcelain pots and pottery pots can be used for cultivation.

(2) flowerpot size: asparagus can be planted in pots with a diameter of 14-18 cm. Now it is cultivated in flat bonsai pots.

two。 The pot method of asparagus culture

When the seedlings grow to more than 5 cm, they can be divided into pots and planted in pots with a diameter of 7 cm and 10 cm. The basin soil should be mixed with 5 parts of rotten leaf soil, 2 parts of garden soil, 2 parts of river sand (sand soil) and 1 part of rotten barnyard manure.

Asparagus is a flower cultivated for many years, but the pot should be changed once a year before sprouting in early spring, the old soil should be removed and the new culture soil should be replaced; according to the plant size and growth, the larger pot should be replaced or the original pot should be used; the withered branches and yellow leafy branches should be cut off to maintain a beautiful plant shape.

3. Watering method of asparagus culture

Watering is the key problem in the cultivation and management of asparagus. Therefore, watering has become an important measure to raise asparagus well. Too much watering, basin soil is too wet, easy to cause root rot, leaf yellow shedding; too little watering, basin soil long-term drought, but also easy to cause leaf tip yellowing and shedding. Therefore, the amount of water and times of watering during the growth period should be determined according to the weather, growth condition and the dry and wet condition of the basin soil.

Watering should grasp the principle of "dry and wet". If you don't do it, you should water it thoroughly. That is to say, when the surface of the basin soil is dry, the water should be watered until the bottom of the basin is watered; you cannot pour "half of the water", that is, the amount of water only moistens the topsoil, and the soil below is dry, so that the bottom roots can not absorb water, so that the branches and leaves will be withered and yellow. When the weather is dry or hot, in addition to keeping the basin soil moist, it is also necessary to often sprinkle water on the ground around the plant and spray the branches and leaves with clean water to increase air humidity. In winter, watering should be controlled, watering times should be reduced, and branches and leaves should be sprayed with water close to room temperature every 5 to 7 days to keep the plant green and fresh.

4. Lighting requirements of asparagus culture

Asparagus is a shade-loving flower that grows well under the condition of scattered light. The sun is not strong in early spring and autumn, so it is good for growth to be placed in a sunny place indoors; in winter, it should be placed in a sunny place; after summer, it can be moved to a cool place outside without direct sunlight or where there is bright scattered light indoors.

5. Fertilization methods for asparagus culture

Asparagus prefers to be fat. In order to make the plant grow healthily, fully mature thin organic liquid fertilizer can be applied every 15 to 20 days in spring and autumn, nitrogen, phosphorus and potassium fertilizer can also be applied, and 0.1% urea and 0.1% potassium dihydrogen phosphate mixture can be applied. Stop fertilizing during hot summer and overwintering. However, fertilization should also be controlled during the growth period to avoid overgrowing and drawing growing vines, destroying the plant shape and affecting the ornamental effect. In order to make the plant low, it is necessary to apply less liquid fertilizer, especially less nitrogen fertilizer.

6. Four Seasons Management of asparagus Culture

(1) Spring management

From March to April, the old plants of asparagus were changed and pruned properly before changing pots. As asparagus likes the damp environment, it can be decorated indoors for a long time. However, due to the low indoor air humidity, attention should be paid to increasing indoor air humidity. Spring temperature is suitable, asparagus growth is more exuberant, seedlings can be fertilized twice to ensure adequate water supply, while pay attention to increase air humidity, otherwise the leaf color is easy to aging and fall off, affecting ornamental.

(2) Summer management

In summer, asparagus can be placed in a brightly lit place to keep the basin soil moist, sprinkle more water around it, strengthen ventilation to cool down, and do not apply fertilizer.

(3) Autumn management

When the temperature is cool in autumn, asparagus will grow again. Attention should be paid to the supply of water and fertilizer and the supplement of air humidity. After the temperature drops at the end of autumn, we should pay attention to maintain the indoor temperature, gradually move the asparagus to the place with light by the window, reduce the watering times, and keep the basin soil moist.

(4) Winter management

Asparagus is not resistant to cold. The temperature below 5 ℃ will cause defoliation, and the room temperature should be kept above 5 ℃. At this time, asparagus is in a state of stagnant growth, so we should ensure a certain amount of light, reduce watering, make the basin soil slightly dry and do not apply fertilizer. When the room temperature is kept above 10 ℃, asparagus can also grow normally, so the basin soil should be moist and no fertilizer should be applied.

Points for attention in bamboo culture:

The main results are as follows: (1) if it is found that the new branches of asparagus turn yellow, 20 times of rotten liquid fertilizer or 1000 times urea solution should be applied 1-2 times, and the light should be increased in the morning and evening.

(2) asparagus likes to be warm, moist, semi-overcast and not cold-resistant. In the south of the Yangtze River, you can't spend the winter in the open. Potted asparagus should be placed in the semi-shade which is not directly exposed to the hot sun in summer and autumn and in the south-facing sun shelter in winter.

(3) potted asparagus should be cultivated in loose, well-drained sandy soil containing humus. In order to cultivate asparagus, it is best to choose mud basins with good drainage and gas generation performance, and the lower layer should discharge rental sand and stones as drainage layer.

(4) the key problems in the cultivation and management of potted asparagus are fertilization and watering, avoiding rain and direct sunlight, otherwise it is easy to cause scorched branches of asparagus and plant color to turn yellow. In the growing period, do not apply thick fertilizer, depending on the growth of seedlings, appropriate application of thin light fertilizer to control nutrients, do not make the plant grow too much and keep the plant shape beautiful. Generally speaking, fully fermented liquid cake fertilizer and water (bean cake or vegetable cake) is applied every 7 to 10 days, with a concentration of 30% fertilizer and 70% water. If the plant grows vigorously, when growing vine branches, you can stand or trim properly.

(5) although asparagus likes to be wet, it is not allowed to water too much, the stagnant water in the basin can not be drained for a while, and the root is easy to rot, even causing plant death. With less water, drying on the basin will also cause yellow leaves or scorched tips. Therefore, whenever the soil surface turns white, it needs to be watered thoroughly. The standard is that after the water is thoroughly watered, the water can be discharged quickly from the bottom of the basin. It is better to be a little wet in the high temperature growing season and dry in the low temperature dormant season. High temperature in summer should be sprayed on the leaf surface, and water close to room temperature can be used to wash the leaves in winter to keep the leaves clean and alive.

What if the leaves of asparagus turn yellow?

1. Strong light exposure. Asparagus culture like semi-shade, summer should not have a strong column of 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 wrong. 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, generally not dry and watered thoroughly, but do not let the basin surface be watered too much 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 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.

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.

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 will also cause asparagus leaves to yellowing and fall off because of high radioactivity, and will also cause stem drying up over a long time, so pay attention to it when placing flowerpots in asparagus culture.

Asparagus bonsai is very beautiful, especially in winter is very easy to die, it is necessary to give asparagus some temperature in winter, so that it will not die, raise bonsai, it is easy to die because of the soil, this requires good attention.

Culture methods and matters needing attention of asparagus [figure]

Asparagus, also known as Pinus elliottii, Phyllostachys pubescens, Phyllostachys pubescens and so on, is a kind of climbing plant, the plant is several meters high. As asparagus is a potted foliage plant, its ornamental value is very high, can be put in the living room, study and other places for breeding, and it can also purify the air. The root of asparagus is a kind of medicine, which has the function of moistening lung and relieving cough for acute tracheitis. Today, let's take a look at the breeding methods and precautions of the article. The pot soil of asparagus culture method asparagus likes to grow in loose, fertile, well-drained sandy loam rich in humus, so when breeding, garden soil, rotten leaves, compost soil and sand can be mixed in accordance with the proportion of 4RV 2RU 2RU 1 to cultivate asparagus, and it is necessary to change soil and fertilize it regularly during culture. If too much fertilizer is applied, it is easy to burn roots, so it is necessary to pour the pot to remove the fertilizer, irrigate the soil with clean water, and then put it into the new culture soil for culture. The watering method of asparagus is a kind of drought-resistant plant, but if it is watered too much, it is easy to cause its roots to rot. Too little watering will lead to the withering and yellowing of its leaf tips. Therefore, in the process of watering, it must be watered according to the weather and the drought of the basin soil. Especially in the case of hot and dry weather, it is necessary to spray foliage with water to humidify and cool down. In winter, it is necessary to water less. The demand for fertilizer of asparagus is not great, but it can not be short of fertilizer, because it is limited by pot soil culture, it is necessary to replenish nutrients in time to meet its growth needs. When applying fertilizer to asparagus, we must follow the rule of more and less amount, and do not apply concentrated fertilizer, otherwise it will cause leaf yellow. generally, we can apply rotten thin liquid fertilizer to asparagus once a month. In its growing period, it is necessary to apply thin fertilizer containing ammonia and phosphorus 1-2 times a month to promote the growth of branches and leaves. Asparagus culture methods the light of asparagus can not be exposed to strong light, especially in summer, it should be placed in a cool and ventilated place for breeding. Asparagus is also a plant that is afraid of wind and rain, so during the breeding period, we should not only pay attention to its good ventilation, but also put it in a place of light to introduce sunlight in appropriate weather. As asparagus likes to grow in a clean and well-ventilated environment, it must be raised in a clean and ventilated place in a society where it is placed. The cultivation method of asparagus is pruned during culture, in order to make the shape of asparagus more beautiful, we can prune it properly. When the growth position of the leafy branch on the main branch is not ideal or is missing for some reason, short pruning can be carried out in the appropriate position of the main branch in order to force the hidden bud to germinate. Pruning can also be carried out in its growing season, because pruning in the growing season is generally high and easy to sprout new branches, but it is necessary to appropriately reduce the amount of water after pruning, and never make the basin soil too wet, otherwise it will easily lead to pruning failure. Points for attention in asparagus culture 1. When watering asparagus, it should not be too much or too little. Although asparagus likes to be wet, it is not allowed to be too wet. If the basin soil is too wet and the drainage is not smooth, it will make the roots retting. Watering too little or no watering will cause large evaporation and small absorption of asparagus, resulting in leaf scorch tip shedding. 2. Asparagus likes to grow in clean and ventilated places. If damaged by harmful gases such as smoke, gas and pesticides, it will cause its leaves to turn yellow, curl and even die. 3. After pruning asparagus, it is necessary to reduce the amount of water to starve it and not let its basin soil get too wet. Conclusion: asparagus is a kind of plant with slender branches and leaves, tall and straight beautiful, dense green and chic posture, and it is also a good foil plant for cut flowers, bouquets and baskets. Whether it is used as a foil, or pot culture, it has a high ornamental value. The above is the introduction of asparagus culture methods and matters needing attention brought by the editor. After reading the introduction of the editor, I believe we all have a better understanding of it. Culture methods and matters needing attention of asparagus what to do about the yellowing of asparagus leaves

Culture methods and matters needing attention of asparagus

[propagation and cultivation of asparagus]

The main results are as follows: (1) asparagus propagation: there are two kinds of asparagus: sowing and ramet. After growing for 3-4 years, asparagus can blossom and bear fruit in autumn, and the fruit will change from green to brown (about December). After it is fully ripe, it will be harvested and dried for storage. From February to March of the following year, it was planted in a shallow basin, covered with soil twice the size of the seed, and covered with glass or plastic film.

The temperature should be kept at 20-25 degrees Celsius and the soil should be moist and loose. It takes about 40 days for seedlings to emerge.

When collecting seeds, we should first cultivate the mother plant, and when asparagus blossoms, do not move the direction of the flowerpot, otherwise it is easy to cause flowers to fall, and the fruit should be fully ripe before harvest, otherwise the seed germination rate is low.

Ramet propagation: there are more clump branches of large plants in 4 ~ 5 years, and they can also be propagated in spring and autumn, but the plant shape is not necessarily beautiful.

(2) cultivation of asparagus:

① soil: loose and fertile soil with good drainage should be selected. 5 samples of available rotten leaf soil,

2 parts of garden soil, 1 part of rice bran ash, 1 part of sandy soil and 1 part of rotten organic fertilizer were mixed, and the basin soil was changed once every 2 to 3 years.

② fertilizer: generally apply 5 times diluted bean juice water or human feces, chicken manure and so on every 10 days in spring and autumn. No or less fertilization in summer and winter.

③ boil water: the basin soil can be a little wet in spring, summer and autumn, but it should also be breathable. If the basin soil is too dry, the leafy branches will turn yellow from top to bottom. Asparagus likes the air humidity is high but the environment is ventilated, can often spray water to maintain humidity.

④ illumination: asparagus is a shade-loving plant, which grows well under scattered light, so it is suitable for indoor cultivation. It can be properly exposed to the sun in spring and avoid direct sunlight in summer.

⑤ temperature: asparagus is not resistant to cold and frost, room temperature above 5 ^ can safely survive the winter.

⑥ pruning and shaping: 1-year-old asparagus is graceful and shaped like a pine tree, but with the growth of the plant, the later branches will grow into a climbing type, so it can be properly supported and tied up to make it grow luxuriantly and keep the plant neat and beautiful. However, if you want to maintain a low shape, you need to prune the old leaves and yellow leaves at any time, and to find new branches that are overgrown, you should pick the growing point of the bud tip in time so as not to grow too long into a climbing type. During the growing period, asparagus needs to cut off the dense branches, weak branches and dead branches in time, so as to keep the plant shape beautiful, ventilated and transparent, and conducive to growth. Pruning the old stem and climbing stem at different heights can promote the germination of new branches and leaves from the bifurcations of the stem at the lower end of the incision, which can make the plant shape have different modeling effects.
