Hibiscus flowers are an ideal addition to any garden or landscape while they are alive and fresh, and to any decor when they are dried out. When you dry hibiscus blooms, you are preserving them so they will last for long periods of time in floral arrangements. It is best to use silica gel to get the best drying results.
Use pruning shears or scissors to cut the bloom off the stem.
Use a container that is large enough to hold the bloom and add a ½-inch layer of silica gel into the bottom of it evenly.
Set the hibiscus bloom carefully into the container with the blossoms facing up toward you, straight. For containers that hold multiple hibiscus blooms, make sure the flowers are not touching.
Sprinkle the silica gel lightly and carefully over the top of the blooms. Make sure that the petals aren't moving when you sprinkle the gel. Do this until the flowers are completely buried.
Seal the container with an airtight top and let it sit in a room temperature area for about three to four weeks.
Check the hibiscus blooms to make sure they are dry after Step 5. When they are dry, the petals feel crisp.
Pour out the majority of the silica gel into another container to remove it from the flowers.
Reach in carefully to the flower's container and lift them out by the base to remove them from the gel. Use a soft bristled brush (like a paint or makeup brush) to brush off any remaining gel from the petals or stem.
