      Looking closer
      Five-lobed leaves are especially
      vulnerable to damage caused
      by intense heat and wind.
      Defoliation reduces the size of
      the leaves and causes another
      burst of growth, but it also
      weakens the tree. You must
      be careful how much and                                     Avoid over-dense
      how often you defoliate.                                    branching by thinning
