1、 Basin soil

For loam with good soil permeability, strong drainage and rich humus, it is best to change the basin once a year for indoor maintenance, remove part of the old soil and replace it with new soil

2、 Temperature

The minimum temperature should be kept above 10 ℃, and obvious freezing injury will occur below 5 ℃, which is manifested in yellowing and falling off of leaves. Dormancy also occurs in summer when the temperature is above 32 ℃

3、 Light

Asparagus likes bright light, but it can't be directly exposed to the sun, so it should be placed in a bright and scattered position

4、 Watering

The water requirement of asparagus is generally to keep the basin soil slightly wet, and the watering shall not be too much or too little, otherwise there will be yellow leaves, fallen leaves and falling needles

5、 Fertilization

During the growth period of asparagus, the requirements for fertilizer are not too high. It is OK to apply thin liquid fertilizer twice in spring and autumn, and there is no need to apply fertilizer too much and frequently

6、 Erection support

Asparagus is a kind of vine plant. With the increase of plant growth and time, we should pay attention to the scaffold and let it climb, otherwise the plant shape will be disordered

7、 Precautions

1. Prevent too strong sunshine. Under direct sunlight, the leaves will turn yellow, fall off, and even wither

2. Like to be wet in maintenance, but avoid ponding, and do not bear drought at the same time. In addition to considering the water content in the basin soil, we should also consider the size of air humidity, and the air should be moist enough
