Some people use a desiccant, a chemical drying agent, to preserve flower bouquets. While desiccants preserve blossom colors better, the cheaper, easier method of hang drying preserves whole bouquets better. Desiccants are more suitable for preserving individual blooms. Hang drying takes longer than a drying agent, but what you invest in time, you save in money. Start the hang drying process before flowers start to wilt, either right after picking or receiving, or within a couple days.
Cut the stems of the flower bouquet to make them even. The ends all stems should meet.
Tie a piece of twine around the bottom of the stems, leaving a long enough loose end to tie to a hook.
Tie the loose end of the twine to a hook or a hanger in a closet, attic, pantry or other dark room. Choose a room with low humidity; refrain from using garages or basements, which are typically humid locations. High humidity will not allow the flowers to dry properly.
Check the flowers after a week to see if they have dried. Fully dried flowers will appear about half the size of the original blooms and will feel crisp.
Store the bouquet in a vase for display. For longer storage, place the bouquet in a shoebox with a few air holes poked through each side of the box. Wrap the flowers in newspaper before placing them in the box. Handle dried flowers carefully; these delicate flowers break easily.
