When the bamboo used for flower arrangement is cut off, the trunk should pass through the metal drill rod from the upper incision and down into the internode interlayer, leaving only one layer at the lowest node and pouring water;

If pruning is adopted, the interlayer will pass through the lower incision, and then it will be filled with clear water and blocked with thick plastic plates. Pour old water every 3-4 days, then inject new water, and spray leaves 1-2 times a day for two weeks.
