  • Question
    What do I do if branches on ninebark look dead on the inside, but the ends are blooming?
    Community Answer
    Put small cuts in the branch starting from the end and working your way toward the trunk. If it is green, it is fine; if it is dry, cut it off.
  • Question
    My ninebark has a bad case of powdery mildew. I have not been able to keep under control. Should I cut it right down to the ground? I have a very large flower garden and am concerned.

    First, prune the leaves that are heavily infected. Then sprinkle some cinnamon powder on the entire plant. This is highly effective, however slightly heavy on the wallet!
  • Question
    Exactly how late can I prune? All my nine barks are out of control and I am super reluctant to hard cut as this is the first year out of several that they have grown well.

    It is best to prune and trim your ninebark shrub during its dormant period, after the end of fall and before the start of spring. Once the plant has stopped blooming, you can perform some light pruning to remove any stray branches.

    Ninebark looks best when pruned minimally and allowed to retain its natural size and shape. Cut out dead, damaged and crossed limbs in early spring. Up to a third of older branches can be removed to improve air circulation. Since ninebark blooms on old wood, shape as needed just after flowering.
