How to care for petals Eliminate moisture from external surfaces of petals. Spread the petals out on a paper towel or cloth and lightly pat them with a paper towel or cloth to remove any excess moisture. While the freshest petals are full of moisture on the inside, too much moisture on their outsides can compromise their freshness, causing them to become soggy, moldy and discolored. Line the inside of the petal bag with paper towels to absorb excess moisture from the petals. Store petals in sealed bags. · Keep them in a cool place when not in use. A refrigerator is an ideal location to store fresh petals. Make sure the refrigerator is not too cold, which may cause the petals to freeze; once they thaw, they will be soggy and discolored, so avoid storing under 35F.
