A bouquet arranged in floral foam or oasis would rot in the silica gel. There is
a maximum amount of moisture that the silica gel can absorb. Floral foam holds more
moisture than the silica gel can absorb. A hand held bouquet could be dried intact
but we choose to take it apart so that we can ensure the best shape of the flowers.
Also, flowers shrink a little during the drying process so a bouquet that is dried
intact becomes loose – losing the original shape of the bouquet.
