Scissors, knife, carbendazim solution or chlorothalonil, potassium permanganate.
Step 1: observe whether the hydroponic culture of the bamboo is odorous and turbid, whether the leaves of the bamboo are yellow, and whether the roots are rotten.
Step 2: cut off the rotten place with scissors, and clean up the rotten root.
Step 3: soak the root of the cut bamboo in carbendazim solution for 3 - 5 minutes.
Step 4: put a third of the water in the water culture bottle, and put the soaked bamboo in it.
At last, I want to remind you that the hydroponics bottle of Lucky Bamboo should be used after disinfection, and the water should be changed twice or three times a week. The Lucky Bamboo should be placed in the place of astigmatism and ventilation to avoid explosion.
