Hibiscus traditionally produce more flower buds than they can develop. They're kind of over-achievers, but they just don't have the resources to support all of the flowers, so they drop some of the buds. With that said, hibiscus flower buds are sometimes targets of a tiny worm called a bud worm. The adult lays an egg just inside the unopened flower bud. The egg hatches into a little green worm who eats it's way through the petals and then exits through a tiny hole. Check the unopened buds carefully for these pests. Or, simply pick a few of the unopened flowers and place them in a plastic baggie. The worms will eventually wiggle their ways out of the buds. Because the adults fly and the larvae are protected inside the unopened buds, control is difficult. Bud worms are usually only active in the spring (and in Florida, the fall) so the damage is limited to those times of the year.
