Asparagus, once raised and once dead, turns yellow. How about asparagus?

The key problem of asparagus 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. During the growing period, thin liquid fertilizer 1 ~ 2 times a month should be applied, and thick fertilizer should be avoided, otherwise the branches and leaves will turn yellow. When modeling plants, we can reduce the amount of fertilization, so as not to affect the beauty of plants, and 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, so as to avoid yellowing 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.
