Why Hibiscus Buds Drop and How to Fix It

Double-flowering hibiscus varieties are more prone to bud drop than others. If temperatures in your area reach 90°F or above, heat stress is likely the cause. Provide midday and afternoon shade. Fertilize weekly with a diluted liquid fertilizer (a balanced 20-20-20 formula high in potassium works well) and water evenly—avoid both drought and waterlogging.
