Most of my potted hibiscus are making buds that fall off just prior to blooming. The budding is very prolific but flowering is limited. Used a slow release 10-10-10 fertilizer this spring, and growth has been good. Leaves are a healthy green. Water twice a week with thorough soaking. Live in Savannah, Georgia where the temperature runs a humid 90+ degrees. Will appreciate anything you have on how to keep the buds from falling off.
