After the flowers in the mature season are harvested, they are cut and hung in dry and hot indoor air to evaporate the water. In order to prevent tissues from shrinking and keep their natural color better, please try to dry them quickly with hot air. When hanging, put the cut flower head down, so that the top of the stem remains hard during drying. You can hang the cut flowers on iron wire or shelves to dry, and don't use plastic bags, because this will prevent the diffusion of water and cause mildew. When making dried flowers, they should be cut in dry weather to facilitate drying. The flower stems should be kept for a long time, and the leaves should be removed, because the leaves prolong the dehydration process and often shrink and lose their ornamental value. Large cut flowers (such as delphinium) should be hung on a single branch to dry. If they are tied into bundles, they will easily crush each other after drying. Generally, cut flowers can be tied into small bundles, and the flower heads are separated from each other so as not to be damaged by squeezing. After a few days, the cut flowers will slowly dry, feel brittle when touched by hand, and the petals will become fibrous. At this time, they have been made into dried flowers and can be used for decoration. Use clean and dry fine sand to find a piece of printing paper to make a paper box that can hold flowers. Bury the flowers in a paper box with fine sand and put them in a dry place. It will take two weeks.
