Select rose blooms a few days before their prime, and only the perfect blooms that are completely dry, no dew. Past prime roses usually drop their petals too easy when dried, and damaged blooms are unsightly in dried arrangements. Pick only on dry days (mid-morning is best) -- avoid any and all contamination from rain and dew.
Purchased at a craft or nursery supply store, Silica gel looks like sugar with small blue crystals in it, and can be used repeatedly, making the cost fairly practical. The gel works as a desiccant that pulls moisture out of the flowers, resulting in spectacular dried blooms. The flowers appear almost fresh, although the color darkens somewhat.
To reactivate the gel after original use, place it in a baking tin in a low temperature (200°F) oven for about an hour.
Cut egg cartons to fit inside the airtight containers. The egg cartons will support the shape of the individual rose blooms. Slowly pour silica into the bottom of the carton. Carefully place each rose in separate cups of the egg carton, then cover each with silica. Close the container tight.
Check the roses after a couple of days to see if they are dry. Don't leave them in too long or they become overly crisp. Tip the container to remove the silica and handle the roses carefully. Lift them out with a small spoon. Store the flowers in a cardboard box with a layer of silica gel in the bottom to prevent them from becoming damp (roses will reabsorb water outside the box).
Spray the blooms with an inexpensive hair spray, or sealer from a craft store, to preserve the color and make the roses less fragile to handle. Dried flower arrangements will last 6 to 12 months, or longer, if you protect them from moisture and direct sunlight. Store the arrangements in plastic containers. To freshen up the design, re-spray with a sealer or use a hair dryer on the lowest setting.
