You can also use silica gel to dry your flowers. (Silica gel is the stuff that you find in your shoe box in little packets). It removes moisture from flowers without crushing them. This works great for very delicate flowers such as hydrangea, roses, carnations and asters. You can purchase silica gel at any craft store. All you need is an airtight box (preferably plastic) and silica gel. Lay a bed of gel in the bottom of the container. Place your flowers on top of this bed and gently sprinkle the silica gel on the flowers until they are covered. Using a spoon works best for this to get the gel into the crevasses without crushing the blooms. Cover the box and wait 48 hours. That’s it! Silica gel works very fast and the flowers hold their color. The great thing about silica gel is that it can be reused. You just need to place the silica gel onto a baking sheet in your oven at 200 degrees to dry it back out again.
For the most natural appearance of dried flowers, try glycerine. This is really preserving and not drying, but the results are wonderful. The foliage on the stems will stay a bright green and the flowers will be a bit sturdier. Prepare the stems by removing any bottom leaves. You may want to thread a piece of florist wire into the flower head to keep it from drooping, or tie the stem to some type of support, like a skewer. Mix together one part of liquid glycerine to 1 part of warm water for fresh flowers and one part glycerine to two parts of water for woody stems. Submerge the stem end only into this mixture. This process can take 2 to three weeks, replace any absorbed solution. Once preserved, remove and rinse the stems, then wipe off any mixture that might have seeped out of leaves.
