First, choose fresh osmanthus, pick it and put it on a clean paper towel to dry.

Next, prepare a dry glass bottle, put the dried osmanthus into the bottle, and cover the bottle tightly.

Then put the bottle in a ventilated and dry place to avoid direct sunlight.

Open the bottle cap every day to breathe, and after a few days, the moisture of osmanthus will completely evaporate and become dried osmanthus.
