How to Dry Flowers

The five methods at a glance

Clemson Cooperative Extension (HGIC 1151) describes the main ways to preserve flowers. The method you choose depends on the flower and the look you want:

All of these except microwave drying work by drying the cut flower slowly, which is what preserves a lifelike colour and form.

Air-drying: the classic "hang and dry"

Air-drying is the oldest and simplest method, and the one the extension guide calls the classic American approach. The essentials:

1. Cut the flowers just before they are fully open.
2. Tie them in small bunches.
3. Hang them upside down in a warm, dry, dark place.

The darkness is the part people skip: it is what preserves the flower colour. Flowers preserved this way become very stiff, and there are honest caveats — blue and yellow flowers hold their colour when air-dried, but pink flowers fade, and roses and peonies shrink somewhat.

Flowers named as good air-drying candidates: baby's breath, cattail, statice, celosia, dock, goldenrod, heather and pussy willow.

Desiccants: silica gel, borax and sand

Embedding flowers in a granular material — a desiccant — is the method the extension guide calls the most commonly used, and many consider it the best all-round. The procedure matters as much as the material:

1. Put about an inch of desiccant at the bottom of a container.
2. Cut the flower stem to about half an inch and stand it in the centre.
3. Pour the material around the perimeter, away from the petals, building up about an inch.
4. Tap the container so the material settles around the flower without weighing the petals down.
5. Cover completely, then add an inch above the flower.

Silica gel is not a gel but a granule that can absorb about 40 percent of its weight in water. It suits quick-drying flowers and tightly packed petals like roses, works best in a sealed container, dries flowers in about a week, and can be oven-dried at 300 °F and reused.

Borax methods mix borax with white cornmeal (2:1) or sand (2:1). Results are less stiff than air-drying, but particles can cling, and sand's rough edges may puncture petals. The flowers can be "burned" if embedded too long — about 10 days for cornmeal, 16 for sand.

Pressing flowers

Pressing is the most familiar method: place the plant material between the pages of a book, close it and add weight. Specialised plant presses give excellent results. Violets, pansies, larkspur and ferns preserve well this way, and pressed material is perfect for framed displays.

Pressing produces flat specimens, which is its strength and its limitation — you cannot press a three-dimensional rose and expect it back. For flat, botanical-style displays and for keepsakes like pressed wedding flowers in a frame, it is the right tool.

For foliage specifically, the extension guide describes heat pressing: place leaves between two sheets of waxed paper and press with a medium-hot iron, using fresh paper for each pressing. This preserves the flexibility and the autumn colour of leaves.

Water-drying and other methods

Some flowers dry best by being given water — briefly. The stems go into a couple of inches of water, which the flower takes up while the rest evaporates, in a dry, warm, dark place. Hydrangeas, yarrow, bells-of-Ireland and celosia dry well this way.

Foliage has its own dedicated methods. Glycerizing lets the stems absorb a glycerin and water mixture, which is ideal for magnolia and mistletoe and works well for ivies, mahonia, eucalyptus, boxwood, beech, camellia, oak and rhododendron. Mature leaves work best.

The extension guide also covers restoring colour to dried material — chalking it with soft chalk and a camel's-hair brush, then moisture-proofing with a spray — which is worth knowing if your dried bouquet has faded.

Putting the methods together

For most home projects the decision is simple. Wedding bouquet keepsakes: press a few stems, and dry the roses in silica gel. Garden bunches: hang them to air-dry. Hydrangeas: try water-drying. Framed flat flowers: press.

The extension guide's honest framing is that no single material is best for every flower, and a method that works for one person may not work for another with the same flower — there is a real element of practice involved. Start with the cheapest method (air-drying), learn how your flowers respond, then invest in silica gel for the specimens that matter most.

And if you would rather buy them than make them: the arrangement ideas guide covers how to use dried stems in centrepieces, and the flowers-by-season reference shows which fresh flowers are worth drying in the first place. To keep the fresh ones alive long enough to enjoy before they are dried, the care guide is the starting point.

One practical note on the timing of cutting: the extension guide is specific that flowers for drying should be cut just before they are fully open — at that point they have the colour and form to preserve, and drying will complete the opening rather than fade an over-mature bloom. Cut in the morning if you can, and get the stems into the drying method promptly rather than leaving them in a vase first, because every hour in water is a step toward the fresh-flower stage you are trying to skip.
