1. Fill the bottom of the container with sponge or stone to fix the root, and then fill the container with nutrient solution until the liquid level just passes through the mesh for fixing the root. Nutrient solution can be purchased from agricultural suppliers, prepared by purchasing nutrient powder, or used as nutrient solution by digging fertile soil and mixing the leachate obtained by soaking plant ash in clear water.

2. Then you can buy seedlings and plant them. Go to the vegetable market to buy those stout watercress, and directly use seedlings for cutting. Try not to use weak seedlings, because they will not germinate vigorously in the future. If you cut with the tail, you should use the tail uniformly; If it is segmented shearing, it is necessary to segment shearing, and the two cannot be mixed, otherwise it will easily lead to uneven growth and unfavorable harvesting. Soilless culture only needs one or two nodes to surface.

In the first week after logging, it grows on its own without any management. After a week of topdressing, you can apply some flower fertilizer or vegetable fertilizer, which is sold in agricultural distributors and other places; You can also apply fertilizer by supplementing fertile soil or plant ash lotion. 15 to 20 days after cutting, the first harvest can be carried out, and fertilizer should be applied once after harvesting. After the first harvest, the general harvest period is shortened to about 10 day, and topdressing is performed once every harvest. In the process of growth, we should always pay attention to injecting nutrient solution to keep the liquid level stable.
