Preserve fresh flowers for months, even years, through the process of air drying. "Air drying or hanging is the easiest and best method for preserving flowers," according to Ronald C. Smith, a horticulturist for the North Dakota State University Extension. If you desire preserving flowers from a special occasion or using in crafts, air drying is the best method of preservation.
Select fully open flowers. Harvest in the cool morning, but after dew has evaporated from the flowers.
Cut the stem with a pair of clean, sharp scissors or garden shears. Cut as much or as little of the stem that you would like to preserve.
Separate the flowers into smaller bunches so as not to crush them. Tie each bunch together at the end of the stem with a piece of twine.
Hang the flower bunch upside down from a hook or hanger in a dry, dark location such as a closet or attic. Do not hang flowers in humid conditions, such as those found in garages.
Check flowers every few days. Adequately dried flowers feel crisp to the touch and appear much smaller in size than before drying.
