1. Hydroponic method

(1) method 1: select the soil-cultivated begonia with good plant shape, remove the soil, cut off the withered shoots, withered leaves and rotten roots, disinfect the 10min with 0.1% potassium permanganate solution, rinse the roots with clean water, plant them in a transparent container, and inject clear water into the root system. Change the water once every 1-2 days, and the water bacon can grow in 5-10 days.

(2) in the second method, the sturdy branches were cut, dried for half a day or 1 day, directly inserted in clean water, changed into water once in 1-2 days, and water bacon could grow in 1-2 weeks.
