Potted asparagus is usually mixed with 1 humus soil, 2 parts garden soil and 1 river sand as the base material, and a small amount of decomposed animal manure is added as the base fertilizer when planting. The key problem in its cultivation management is watering. Too much watering is easy to cause root rot and yellow leaves to fall off; If there is too little water, the soil in the basin is too dry, which will easily lead to yellowing of the tip and leaf falling off. Therefore, it is necessary to properly control the amount of watering at ordinary times, so that it will be transparent if it is not done, and the basin soil will always be wet. When the weather is hot, in addition to watering the basin soil, we should also often spray water on the leaves to improve the air humidity; After winter, the amount of watering can be reduced appropriately. Apply dilute liquid fertilizer 1-2 times a month during the growth period, and avoid applying thick fertilizer, otherwise the branches and leaves will turn yellow. In plant modeling, we can reduce the amount of fertilizer, avoid unnecessary growth and affect the beautiful modeling of plants, and at the same time pay attention to proper pruning and modeling. Suitable for growing in a semi-cool and ventilated environment, pay attention to proper shading, especially in summer and autumn to avoid direct sunlight and yellow leaves. It is best to cultivate in a place with a certain diffuse light indoors.

The key to asparagus management is watering. Too much watering, branches and leaves are easy to turn yellow, and the growth is not good, which is easy to cause rotten roots. The watering amount should be adjusted according to the plant growth and season. Water should be properly controlled in winter, spring and autumn. Generally speaking, the surface of basin soil is dry before watering. If the water quantity is difficult to master, it can also be done alternately. That is, after watering for 3 ~ 5 times, water 1 times the water permeability, keep the basin soil moist from top to bottom, and do not water much. Water in the morning and evening in summer, and the amount of water is slightly larger.

Potted soil should be watered only when it is dry. Irrigation should be sufficient during the growth period, but not too much, otherwise the roots will rot easily. It is necessary to grasp that water will quickly penetrate into the soil and there will be no water on the soil surface. Use less water after the end of autumn. Organic fertilizer can be applied every 20 days during the growth period, such as decomposed cake and fat water. Keep it indoors in a warmer place in winter.

Although asparagus doesn't like fertilization very much, it should be supplemented with nutrients when potted, especially when plants are ready to be planted. The fertilization of asparagus should be thin and diligent, and thick fertilizer should not be used. In the growing season, the decomposed organic liquid fertilizer is generally applied ~ times every 15 ~ 20 days. Asparagus likes slightly acidic soil. Therefore, combined with fertilization, some alum fertilizer water can be properly applied to improve the soil pH value.

Asparagus should be wintered indoors, and the room temperature should be kept at about 10C in winter, with sufficient sunlight, so it can be moved outdoors for maintenance after April next year.

Asparagus is planted in the ground, with lush foliage and rapid growth of new vines. It must be erected in time to facilitate ventilation and light transmission. Prune old vines with dead branches properly to promote the germination of new vines. Apply bone meal or calcium superphosphate again before flowering to improve the seed setting rate.

As a kind of cut-off asparagus, when harvesting, branches with length meeting the requirements of marketing are selected for cutting, and every 20 branches are bundled for marketing. Generally, the price in winter is more than 20% higher than that in summer and autumn.

Asparagus should be fully watered during the growth period, and the pot soil should be always wet, but it should not be watered too much, and it should not accumulate water, otherwise the roots will rot and the leaves will fall off, reducing the ornamental value. Reduce watering after autumn. During the growing period, apply 1-2 thin fertilizers containing ammonia and phosphorus every month to promote the flourishing of leaves, and other liquid fertilizers can also be used. It should be noted that fertilization should not be excessive during flowering, and liquid fertilizer should be applied twice in May-June and September-10 respectively. The amount of watering should be flexibly controlled according to the size of the plant, with the principle of seeing wet. When the branches of plants are long, they should be tied in time and trimmed properly to keep the plants neat and beautiful.

Asparagus is to prevent the sun from being too strong, so it should be placed in a semi-cool place. Although asparagus likes warmth, its tip is easy to wither under strong light.

The second is to prevent watering too much or too little. Although asparagus likes to be wet, it should not be too wet. If the basin soil is too wet and the drainage is not smooth, the roots will rot. Too little or no watering will cause the leaves to fall off because of the large evaporation and small absorption of asparagus.

The third is to prevent the pollution of harmful gases. Asparagus likes a clean and ventilated environment. If it is stimulated by harmful gases such as smoke, gas and pesticides, its leaves will turn yellow, curl and even die.
