The whole plant should be immersed in a potassium permanganate solution with a concentration of 100 mg/L for 10 to 15 minutes. Then take it out and rinse the potassium permanganate solution with clean water.
4. Plant in a water plant pot. Divide the roots into 2 to 3 groups, insert them into 2 to 3 sieve holes, and pull the roots that have passed through the sieve holes slightly with your hands so that the bulbs are close to the cross ribs in the center between the sieve holes.
