How to cultivate asparagus? Key points of attention in potted asparagus culture

Asparagus prefers a warm, humid, semi-overcast and ventilated environment. It is best to use loose, fertile and well-drained sandy loam rich in rot. Next, let's take a look at the key points of asparagus pot culture.

1. Basin soil

The basin soil for cultivating asparagus should use fertile sandy loam, which should be warm and humid, rich in rotten branches and good drainage. Generally, it can be prepared in the proportion of 4 parts of garden soil, 2 parts of rotten leaf soil, 2 parts of compost soil and 1 part of sand, and the soil should be changed and fertilized regularly. If excessive application of fertilizer causes "watering roots", it is necessary to pour the pot to remove the fertilizer, irrigate the soil with clean water, and then put it into the new soil for breeding.

2. The growing environment of asparagus

Asparagus prefers a warm, humid environment, and does not like a smoky environment. If you put the green apple in the position where there is lampblack at home, the leaves will easily become yellow and dry.

3. Light and temperature

Asparagus likes scattered light and must not be exposed to the sun for a long time, especially in summer, asparagus can not be directly placed in the sun, otherwise it is easy to be burned by the sun. Put asparagus in the shade in summer and bask in the sun in the morning and evening. Asparagus should be moved to indoor maintenance in winter, the outdoor low temperature environment will freeze asparagus, the indoor environment should be kept above 5 degrees Celsius, asparagus can survive the winter smoothly.

4. Watering

Watering asparagus is easy, as long as you keep it dry and wet. When you see that the pot soil is dry, water the asparagus again, do not water too much, if there is stagnant water in the basin, asparagus is easy to have yellow leaves and rotten roots.

In the spring and autumn season, pay attention to do not dry or water asparagus, and try to water as little as possible in winter. when the temperature is hotter in summer, in addition to more watering, you can also use a spray can to spray water on the leaves.

5. Fertilization

If it is found that the leaves of asparagus turn yellow, it is very likely that the nutrient content in the soil is too low. It is necessary to supplement fertilizer to green pineapple, and compound chemical fertilizer can be used. After fertilization, the symptoms of yellow leaves will gradually disappear.

If you are not careful to apply too much fertilizer will also cause yellow leaves, how to deal with it at this time? You can pour out the fertilizer, and then irrigate the soil with clean water to replace the new soil. Therefore, when applying fertilizer, we must pay attention to the application of thin fertilizer and do not covet too much at one time.

Asparagus belongs to the genus Liliaceae, perennial evergreen vine herbaceous flowers, native to southern Africa. Asparagus is not only an excellent potted foliage flower, but also an excellent leaf-cutting flower, which is often used to make flower basket, bouquet, corsage, flower arrangement and so on.

Asparagus likes warm, humid climate and semi-overcast environment. For fear of strong light, the strong sunshine in summer will make the branches and leaves yellow. It is not cold-resistant and afraid of heat. The suitable temperature for growth is 15-25 ℃. When the summer temperature is more than 30 ℃, the branches and leaves will turn yellow. The northern cold region moved indoors in early October, and the overwintering temperature in winter was 10 ℃, and the cold injury occurred when the temperature was below 10 ℃. It is not resistant to drought and should always keep the basin soil moist during the growth period. Asparagus has strict requirements on basin soil, which requires loose, fertile and good drainage. It is generally prepared with rotten leaf soil, river sand and mature organic fertilizer.

Key points of family care

Basin soil

Asparagus is suitable for growing in warm and humid soil rich in rotten branches and good drainage. Asparagus is afraid of smoke and dust, and if it encounters poisonous gases, its branches and leaves are prone to yellowing. For this reason, attention should be paid to putting it in a clean environment during maintenance. Asparagus should be fertile soil, if there is no soil change for a long time, nutrients are in short supply, there will be branches and leaves yellowing phenomenon. At this time, it is necessary to pour mature thin liquid fertilizer or compound chemical fertilizer once a week, and water and loosen the soil in time, so that it can change from yellow to green soon. If the fertilizer is too thick or unmature fertilizer is applied, it is easy to cause "watering the root", resulting in the drying and shedding of the leaves. At this time, it is necessary to pour the pot to remove the fertilizer, irrigate the soil block with clean water, and then change it into the new culture soil.

Watering

If the potted asparagus is watered too much, the soil is too sticky and the drainage is poor, the leaves of asparagus will become scorched yellow and fall off, which will affect the growth of asparagus. Generally need to wait for the basin soil to see dry before watering, spring and autumn season should reduce watering, adhere to do not water, winter control watering. Excessive watering can easily cause root rot and leaf yellow shedding when the basin soil is too wet. When watering, we should pay attention to the water temperature should be as close as possible to the surrounding temperature, so as to reduce the stimulation of water temperature discomfort to the root system. Spray the leaves with water when the weather is hot and dry.

Fertilizer application

Asparagus is not a good fertilizer plant, but it can not be short of fertilizer. Potted asparagus is limited by potted soil, so it is necessary to replenish nutrients in time to meet its growth requirements. Asparagus fertilization should be thin and diligent, do not apply thick fertilizer, otherwise it is easy to cause branches and leaves to turn yellow. The growing season in spring and summer is dominated by nitrogen fertilizer. The mature thin liquid fertilizer can be applied once a month. When the plant is stereotyped, fertilization should be properly controlled to avoid excessive growth and affect the beauty of the plant type.

Light

Asparagus cultivation must not be exposed to the hot sun, summer and autumn hot season, should be placed in a shady and ventilated place. The flowering period is afraid of both wind and rain. At this time, we should pay attention to good ventilation, otherwise the fallen flowers will not bear fruit. When potted, it is suitable to put the potted plant outside to receive sunlight on a sunny day, which is beneficial to its light and function.

Temperature

In winter, potted asparagus should keep the ambient temperature above 5 ℃ to avoid freezing.

Reproduction method

Asparagus is generally propagated by sowing or ramets. Sowing should be carried out from March to April in spring, and it can germinate 30-40 days after sowing. It can blossom and bear fruit after 4 years of normal growth. Asparagus can be propagated separately for 3 ~ 5 years, but the joint of the rhizome should be cut off with a sharp blade, otherwise the plant will recover slowly and its shape will be uneven, which will affect the ornamental effect.

Culture skills of asparagus asparagus

Asparagus originates in South Africa and is distributed in central China, northwest China, the Yangtze River Basin and the south. Its nature likes the warm, humid and semi-overcast ventilated environment, it is not resistant to cold and drought in winter, and avoid direct sunlight in summer; it has extremely high ornamental plants, which can be placed in the living room and study to purify the air and add bookish flavor at the same time. Root medicine can treat acute tracheitis and has the function of moistening the lung and relieving cough. Now let's get up and take a look at the breeding skills of asparagus.

How to raise asparagus

Asparagus, an evergreen ornamental plant, belongs to the genus Ophiopogon of Liliaceae from Africa. It is a common potted landscape in the home. Asparagus is a green vine, the roots and stems are fleshy stems from the stem, relatively soft, and straight upward. It is as jointed as bamboo, implying rising. Because it is like dwarf bamboo, but it has more elegance and literary flavor than bamboo, it is called asparagus by ancient literati. Asparagus to show that the green is not actually leaves, but its leaf-like branches, leaf-like branches are more dense, together like feathers, very elegant. Seen from afar, asparagus is superimposed layer by layer, like green clouds, so it is also called Yunpian pine and Yunzhu, with luxuriant branches and leaves, so it is rated as bamboo Chinese. Generally speaking, asparagus grows better in the first three years, and needs proper pruning after growing up gradually, mainly to observe the leaves. And asparagus placed in the middle of the home, not only play a role in purifying the air, and its fragrance, this fragrance has the effect of relieving cough and moistening the lungs.

Since asparagus is so good, how can we raise it to add to the scenery? First of all, let's take a look at its habits.

Asparagus native to Africa, the climate in Africa is relatively warm, and the soil is fertile, the temperature has been above 15 degrees Celsius. However, asparagus has been growing in the shade, and the ventilation environment is relatively good, generally growing in the mountains, now many people are raised in the courtyard or home, but also with rockery as a landscape match. The requirement for moisture is relatively strict, and it is not hardy in winter and is easy to die.

Asparagus for more than 3 years can be propagated separately, but it should be carried out in spring when dividing plants, which is very important. Then the method is to use the blade to divide the stem and root of asparagus into two to three clumps, so that each clump has three to five branches. Then plant them separately in a prepared new basin. Remember to moisturize and shade after dividing the plant. Otherwise it will cause yellow leaves!

As a family farming, planting asparagus soil is very important, to choose a fertile sandy loam, its soil to ensure moisture. Friends should pay attention! Generally speaking, the adobe can be reconciled with the proportion of four parts of sand stuffed soil, two parts of rotten leaf soil and one part of sand. But friends should pay attention to changing soil and adding fertilizer regularly, so as to ensure the healthy growth of asparagus.

Asparagus is a very "hypocritical" plant, if you water more, then the root of asparagus will rot; if there is less water, then the leaf tip of asparagus will turn yellow and become withered.

So the main points that friends should remember are: pay attention to the weather when watering, the condition of the soil, dry watering, spray watering can be used to humidify and cool asparagus in hot summer.

Here the editor would also like to talk about the daily pruning methods of asparagus for all of you. If the branches and leaves of asparagus cause growth problems due to sun burns or dry soil or lack of fertilizer, all the leafy branches can be cut off. If the growth of a branch is slow, then in order to make the shape of asparagus look good, it can be cut off from the roots at once.

Maintenance methods of asparagus

1. Adequate nutrients to avoid nutrient loss. Some are due to the hardening of basin soil and the decrease of root activity due to poor ventilation, which affects the normal growth of plants. In addition to changing the basin with soil rich in organic matter in spring, we should often loosen the surface of the basin soil and pay attention to strengthening fertilization.

2. Water more and keep moist. Should always keep the basin soil moist, and often spray water to the plant, the water temperature had better be the same as room temperature, and put asparagus in a place with high air humidity. Mixed fertilizers should be properly applied in the growing season to make the plants healthy and strong and enhance their resistance.

3. The amount of water should be appropriate, and too much is not good. It should be moved to the shade or the edge of the curtain window to avoid direct exposure to strong light, and pay attention to not watering too much.

4. Pay attention to the weather changes. When a typhoon comes, asparagus should be moved indoors. Its decay is mainly caused by strong winds in the hot summer season, or long-term stagnant water in flowerpots. So in summer, we should pay special attention to guard against thundershowers or typhoons.

Asparagus is a shade-loving plant, likes a warm and humid climate, can not bear cold, but also afraid of summer heat. The requirements of light conditions are relatively strict, neither year-round shade, but also can not withstand the sun exposure, exposure in the hot sun for half a day will be withered and yellow. Therefore, it is appropriate to migrate asparagus to indoor culture and grow under scattered light to avoid direct sunlight. Keep the soil fertile, draining and breathable, and keep the indoor temperature above 5 ℃ in winter in order to make it safe through the winter.
