How to Air Dry Cut Flowers

It is often overlooked that the vibrant colors from the height of harvest season can be preserved and enjoyed year-round. One of the easiest, thus earliest developed and still most commonly used method for preserving flowers is air-drying.

If you're interested in drying your own flowers, you likely already have all of the materials on hand, and have some place to do the drying. You may even have appropriate flowers growing in your own or nearby fields or garden beds.

Here are some how-to tips, along with some usage and merchandising ideas for preserving the colors of summer, to brighten indoor spaces as the fall and winter months close in around us.

The open space of a barn's loft originally served to keep hay dry. These conditions — dry, airy, and dark — are what's required for drying flowers.

• Dry. The less moisture in the air, the better.
• Well-ventilated. Moving air helps prevent moisture from settling and mold from developing on the plant tissues.
• Dark. Attics of garages, barns, and houses can be choice locations for drying flowers as most lack windows — while not crucial to the effectiveness of drying, a dark location allows the flower to better retain most of its fresh color, and prevents fading. (Alternatively, sun bleaching — intentionally allowing the flowers to achieve that "sun-kissed" look while drying — is sometimes used for autumnal arrangements with grasses, grains, and thin-stemmed flowers.)

You also need something to hang the flowers from. If you are drying only a small amount — a bouquet or two — a couple of hooks to hang the flowers from will suffice. But for drying larger quantities of flowers, stretch a strong wire or two between the rafters to serve as drying lines, in a set-up similar to a clothesline.

Some flowers dry better than others:

• Plants with high water content, such as peonies, generally do not dry as well as those with low or moderate moisture volume.
• Delicate flowers, too, such as carnations, are more difficult to air dry than those made of sterner stuff.

To ensure success, select the species and varieties noted for their suitability to this purpose. Among these, statice, celosia, ammobium, gomphrena, and helipterum (Rhodanthe spp, or paper daisy) are a few of the classics; for foliage and fillers, the ornamental grasses.

Stage

Once you have your preferred flowers planted and blooming, you will want to know which stage of growth is best for cutting.

• Whereas many flowers cut for fresh bouquets are harvested when only a few buds are opened, flowers that are cut for the purpose of drying should be almost fully bloomed. In the weeks when they are drying, the flowers will continue to open, but only slightly.
• There are exceptions , however, so be sure to read the harvest information on the product's webpage or on the back of the seed package.
• For all flowers intended for drying, harvest before the flowers set seeds.
• In addition, mature or over-mature flowers shed pollen, which can make quite a mess, or their petals, leaving you with a bloomless stem.

Be sure to harvest statice (Limonium sinuatum) after the dew evaporates, to decrease drying time as well as risk of mold.

Time of day

• Early morning is the best time to harvest. Since the idea is to dry the flowers, however, you will want to wait until the dew has evaporated. Otherwise, it will take longer for the flowers to dry and increase the likelihood of mold developing.
• As with fresh flowers, cutting in the heat of the day can cause the flowers to wilt. Even in the cool of the evening, the plants may still be recovering from the heat and not at peak quality.

Sun bleaching and mold, as shown on this celosia, cause flowers to lose their peak colors in the drying process.

Dried flowers are relatively problem-free. We've already discussed how the sun can bleach out the color and too much moisture can encourage mold, and how to avoid these conditions.

Another concern is dust collecting on the flowers. Due to the semi-delicate nature of dried flowers, they cannot be easily dusted off with a cleaner and a cloth. For long-term storage, box them them up in tissue paper when they are dry to store them until ready to use.

Some flowers, such as strawflowers, have extremely delicate or brittle stems when dried, and many people will cut the stem right off of these after harvest and run some floral wire through the inflorescence instead, for ease of bunching in the future.

Dried flowers can be kept and stored for up to a year, beyond which their quality deteriorates, with dust or faded colors, in most cases.

As winter growing and season extension practices become more widespread among growers, so too has year-round demand for locally-grown produce. Like other value-added products, dried flowers take winter CSA shares and indoor farmers' market displays beyond vegetables. Think of dried florals as another type of valuable storage crop that needs proper care before being brought to market.

The most common use for dried flowers is to gather than into long-lasting arrangements. Good design is always appreciated, and if the flowers are kept from light while drying, the colors of the blooms will brighten indoor spaces for months to come — a welcome sight in the depths of winter. Disassemble the bunches you dried earlier, and build your arrangements by choosing the components that please you and your customers the most. Secure the stems and embellish as desired.

Seasonal and holiday décor is one of the quintessential outlets for dried flowers. Celosia blooms in all the classic warm fall tones, so they are perfect for Thanksgiving centerpieces. In a month's time, people look toward changing their November decorations for those of the winter holidays — Christmas, Hanukkah, Kwanzaa, Yuletide, New Year's Eve. In addition to bouquet arrangements, evergreen wreathes, roping, and swags adorned with dried flowers provide forms for decoration, even wreaths made entirely of dried flowers.

Small hand bouquets can be well-appreciated as delicate gifts for family and close friends, too. They can also be designed as fragrant Valentine nosegays.

In recent years, winter weddings have become increasingly popular. For parties conscious of the environmental footprint of flowers imported from other continents or hemispheres, dried flowers can provide an alternative. Brides and planners can speak with a grower well in advance of the wedding date — the flowers can be planted, grown, and dried according to specifications in time for the wedding. Furthermore, the bouquet, boutonnières, and any flowers used to decorate ceremonial and reception spaces can all be dried, and kept for more lasting reflection of the big day.

When fall frosts hang in the air and you're rushing to protect and harvest as many vegetables as you can, don't forget your flowers. You worked hard to keep them flourishing throughout the summer. By cutting and drying them, you can get the most out of your blooms, allowing the vibrant beauty of dried flowers to brighten the winter months.

As the local flower industry takes off, there are many great opportunities for avid flower gardeners and farmers in this niche. And for vegetable growers just looking to get into flowers, this may be a good place to begin. Pairing dried florals with a creative flair could develop into a rewarding cottage industry.
