You can choose whether to collect all the individual flowers or cut the whole plant at the base, then hang it in bunches and complete its drying in 2 or 3 days. The place suitable for this purpose is cool, shady and ventilated, so as to prevent mold or rot caused by moisture. We must avoid drying the plants in the sun because they would lose their aromas, and to protect the plants from dust we can wrap them in breathable cloths.
