1、 Hydroponic asparagus method

1. Plant treatment: when hydroponically culturing asparagus, first select a strong asparagus, remove it from the pot, and clean the soil of its root system, which can be washed under the water. If there are old roots, withered roots and rotten roots, they must be cut off and the wound must be disinfected

2. Preparation of containers: when hydroponically culturing asparagus, it's best to choose transparent and glass containers. The size depends on the size of the plants. A net should also be prepared. You can't put the plants directly in the water. Or if you feel troublesome, you can also buy containers directly from florists. Florists generally sell them

3. Put in the plant: when the container is ready, put the asparagus into the net first, so that the root system can be exposed to water. We should also provide a warm and well ventilated environment. Generally, new roots will grow in three or four weeks. Note that the water quality used should be clean well water and river water. If tap water is used, it must be dried before it can be used

2、 Maintenance method of water cultured asparagus

1. Timely water change: during the period of hydroponic asparagus cultivation, the water quality must be kept clean. If water pollution is found, the water must be changed as soon as possible. Before rooting, the water is usually changed once a week. After new roots grow, the number of water changes should be reduced. When there is little water, add water in time

2. Suitable environment: Asparagus likes a warm environment with poor cold resistance. It is best to provide an environment of 15 to 25 ℃. After winter, you must move indoors and control the minimum temperature above 10 ℃, otherwise it is easy to be frostbitten. It is shade resistant and not sun resistant. During hydroponic culture, it is OK to occasionally accept astigmatism, and direct light or strong light must be blocked

3. Topdressing nutrients: the nutrients contained in the water itself are relatively small. The asparagus cultivated in water must be topdressed frequently if it wants to grow vigorously. It's best to add nutrient solution to the water every half a month. Just use the nutrient solution specially for hydroponic culture. If the nutrition is sufficient, the growth will naturally be more vigorous. If not topdressing for a long time, lack of nutrition, prone to various poor growth conditions
