Garden flowers gain second life when dried

“The delicate, ephemeral nature of flowers undoubtedly adds to our appreciation of them,” said University of Missouri Extension horticulturist David Trinklein. “Many literally are here today, gone tomorrow.”

But, flowers can be enjoyed all year long by drying them, said Trinklein, and now is the perfect time to gather the excess from gardens and preserve them for future enjoyment, according to an extension press release.

Follow these tips for successful drying.

Pick flowers and other plant materials destined for drying close to their prime. Many species can be harvested and dried at various stages of development for added interest in dried arrangements.

Always collect more material than you need to allow for damage, Trinklein suggested.

“Use only the most perfect forms. Poor shapes dry as poor shapes. Use only plants and flowers free of insect and disease damage. Damage becomes only more obvious after drying. Pick flowers free of dew or rain. Promptly place stems in a container of water to prevent wilting while gathering,” he said.

Trinklein also recommended several popular methods for drying flowers: air drying, pressing, use of desiccants and microwave drying.

Air drying

Many garden flowers and wild plants can be dried simply by tying them together and hanging them upside down in a warm, dry place for several weeks.

“Choose flowers suited to this treatment such as everlastings and a few others that do not wilt readily. Dry some, such as globe amaranth, in bunches on their natural stems. On others, such as strawflower use wire as stems before drying,” stated the extension release.

Seed heads of many grasses and other plants also can be hung to dry. A few large flowers, such as peony and hydrangea, are sometimes dried this way. But hang large flowers individually rather than in bunches.

Pressing

Sandwich flowers (and foliage) between layers of a clean, absorbent material that can hold the flowers firmly during drying. Porous materials that allow some air movement are beneficial.

“Place flowers between sheets of a non-glossy type of paper such as newspapers or old phone books. Place absorbent facial tissues on pages to speed moisture absorption. Remove tissues and flowers or foliage and replace with fresh, dry tissues and papers at the end of the first week,” states the release. “After placing flowers and tissues in the folded newspapers or books, stack them several layers deep. Place boards beneath and on top of the stack. Put the stack in a warm, dry place with a heavy weight on top.”

Drying with desiccants

At times, air-dried flowers become misshapen. This happens most often with flowers with a high moisture content or a flat, open shape.

“Dry these types of flowers by burying them in one of several desiccants that remove water more quickly than air drying while holding the flowers in their natural form,” states the release.

Trinklein recommended silica gel to dry flowers at home. Silica gel costs more initially than materials containing borax, but it lasts for many years. It also dries flowers more quickly, he said.

Silica gel is sold under several trade names. It is white, but some types contain blue crystals that indicate the amount of moisture that has been absorbed. When these crystals are a clear blue, the material is dry. As they absorb moisture, the crystals gradually turn pink. At that point it is time to dry the crystals in a warm oven before using them again.

Microwave drying

Microwave drying takes only a few minutes and provides dried flowers that look fresher and more colorful than drying by other methods, states the extension office.

“Support material such as silica gel must surround the flowers during heating and drying. Use heat-tolerant glass or microwave containers. Do not cover the containers. Place a cup of water in the oven before starting to prevent excessive drying,” states the release.

Drying times vary: about one minute for smaller flowers or flowers with thinner petals and up to three minutes for dense flowers with many petals. Check frequently since microwave ovens and flowers vary. Microwave drying does not work well on flowers with thick petals.

After microwave treatment, place flowers in a container with silica gel for 12 to 24 hours to make sure they are cool and dry. Microwave-dried flowers tend to absorb air moisture, so spray petals with hair spray or lacquer and store in an airtight container.
