If you are searching for a way to dry flowers you will come across four basic techniques. They are air drying, using the microwave, using a drying agent such as a dissicant or silica gel, and using a glycerine solution. The best time to gather flowers to be dried is right before they bloom and preferably when the weather is dry. If you must pick them when wet, gently blot off excess moisture with a soft paper towel or tissue.
Air drying is the oldest and easiest method, as there is no special equipment needed.
Simply gather your bunches of flowers, tie their stems together tightly with a string or rubberband and hang them upside down. The flower bunches should be hung in a warm, dry, preferably dark place with good air circulation. Although this method is the easiest, it is also one of the longest. Flowers can take up to three to four weeks. When they are dry to the touch, they can be taken down and then sprayed with hair spray or a clear lacquer to help them hold their form and give them shine.
