The hydroponic method of asparagus is relatively simple. You can choose vigorous plants, dig them out of the soil, and then wash the soil at the roots with tap water. If rotten roots are found, they should be cut off in time, then sprayed with disinfectant, inserted into a glass bottle filled with water and maintained under astigmatism.

Feeding methods and matters needing attention

1, lighting requirements

Generally, hydroponic asparagus can not be directly exposed to the sun, and it is easy to burn plants in the sun. Asparagus is very resistant to shade, so we can put it in a cool and ventilated place at ordinary times and directly expose it to the sun in winter. If we usually give it 4 hours of light, it can promote the growth of hydroponic asparagus to be more robust.

2. Change the water in time

Generally speaking, it is very important to change water in time in the cultivation methods and precautions of hydroponic asparagus. Generally speaking, it is necessary to change water every other week, but the temperature in winter is too low and the frequency of changing water should not be too frequent, so it can be changed once every half month to prevent root rot.

3, topdressing nutrition

Although hydroponic asparagus does not need fertilization, if you want asparagus to grow stronger in water, you only need to apply a small amount of Bika water-soluble fertilizer to the water when changing water sources in spring and autumn, and drop nutrient solution every 20 days in winter.
