If you want to obtain a maximum number of dry flowers in a minimum amount of time, use drying method with preheated silica gel, because flowers dry faster in preheated silica gel. Special Method: Drying with Preheated Silica Gel Silica gel has been used commercially for many years. All of these flowers have fleshy stems and very delicate petals and the trick is to dehydrate the blooms rapidly enough to preserve both their vibrant, natural colors and their intricate shapes.
