There are four methods for drying plants: air, glycerin, desiccant treatment, and press drying.
Drying dried flowers with moisture-absorbing agents
When drying with moisture-absorbing agents, hygroscopic substances are used, since even in xerophytes moisture is unevenly distributed – most of all it is in flowers. These can be borax or silica gel, it is better to use them in a mixture with clean fine sand. The substance must be poured in a layer of 1-2 cm, then put the head of the flower on it so that the petals are separated from each other, and carefully covered with an absorber so that each surface of the flower touches. Leave in a dry place, after covering the vessel with porous paper, for 3-5 days. If the plant is dry (this can be checked by brushing off some of the sand with a brush), then carefully remove it and store it in a dry, dark place, hanging the plant upside down. Buttercup, peony, apple tree, dahlia retain their decorative properties best.
Drying dried flowers by pressing
The method of drying by pressing is known to everyone since childhood, when in biology lessons it was necessary to make herbariums. Press-dried plants retain their color and shape for a long time. The only drawback of this method is that the plant loses volume and becomes two-dimensional. For drying in this way, a herbarium folder or a herbarium net is usually used. The cut plant is placed on a newspaper, laid on top with moisture-absorbing paper, then covered with another newspaper and placed in a herbarium folder. This method can be used to dry the flowers of pansies, flax, poppy, clover. Plants dried by pressing in volumetric compositions are used very rarely, but they are perfect for paintings, panels, miniatures. Small flowers can be dried whole, and massive ones can be cut lengthwise and it is desirable to separate the leaves.
