    With a larger tree, I'd go with fall. Even after leaf drop, the roots keep working and will be better able to withstand next year's summer if given a fall head start. Of course, regular watering the first year is important. And I'd resist the temptation to fertilize the first year as well unless a soil test shows deficiencies.

    This shrub prefers well drained soil, so these issues following heavy rains and clay soil are the likely reason for the symptoms you describe.

    If the problem is minor, mix compost into the top 8 to 10 inches of soil to add a surge of nutrients.
    Add earthworms! Worms eat through compacted soil, helping restore a healthy flow of air and water.
    If the problem seems more serious (and you may need an arborist to confirm that), try aerating. By drilling holes into the soil, you break up those compressed particles and provide more air. So, your tree will be able to breathe easier and have better access to nutrients.
    Avoid drilling through roots.

    They are very susceptible to a wide range of insecticides. Myself, I would use Bt. (Bacillus thuringiensis) This naturally occurring bacterium is harmless to you, but will devastate the insect population that is feeding on your tree.
