Answer: Your Rose of Sharon (Hibiscus syriacus) should be regularly deadheaded to keep it looking attractive, and to encourage additional blooms. As soon as the flower petals begin to wilt snap the entire flower off the stem. If you allow them to remain, they will form seedheads. This process directs energy away from additional flower development and results in unattractive capsule type fruits. Your shrub will produce larger flowers if it is pruned each winter - simply cut back the previous season's growth, leaving two buds on each branch.
