Why does asparagus die?

The reason why asparagus turns yellow and dies: (1) Too strong sunlight can easily cause leaves to turn yellow or even die. (2) Improper watering: Asparagus likes wet, afraid of waterlogging, and the soil is hardened and the water permeability is not smooth. (3) The soil in the basin is too dry, and water is poured on it. The soil has been dry for a long time, leading to death. (3) Improper fertilization, such as applying original fertilizer or excessive fertilization, will make the leaves turn yellow and fall off. (4) If the winter tube is not shaded for a long time and the room temperature is below 8 degrees, the leaves will turn yellow and die. (5) Asparagus polluted by smoke is most afraid of smoke and harmful gases, and it is easy to die if it is maintained in a place where the air is not circulating. Asparagus likes warm, ventilated, semi-cloudy and semi-humid environment, is not cold-resistant, and avoids direct sunlight. Suitable for growing in sandy soil with rich humus and good drainage. The key to asparagus cultivation is watering. Too much watering and too wet pot soil can easily lead to root rot and yellow leaves falling off; Too little watering and too dry pot soil can easily lead to yellowing and scorching. Therefore, watering usually depends on the weather, growth and soil conditions. Don't do it right, pour it completely. You can't water "half water", that is, watering only wets the soil surface, and the soil in the basin is still dry. During the growth period of asparagus, decomposed dilute liquid fertilizer can be applied once every half month. In plant modeling, fertilization should be properly controlled to avoid excessive growth and affect the beautiful shape of plants, and appropriate pruning should be carried out. Potted asparagus, it is best to change the pot once a year, and it should be done in spring. When asparagus is hot and dry, spray water to humidify and cool down. Water less in winter and keep the room temperature above 5 degrees. Asparagus is afraid of smoke and dust, and the place should be ventilated.
