I planted a Miss Kim Lilac in April this year, it bloomed well and was very healthy until August. Now many of the leaves have turned brown in spots and others have dropped off. It looks very sick - have I given it too much water? I know the leaves are supposed to turn a nice red colour in the fall but these are definitely brown, curled and unhealthy or have dropped off altogether. Can anyone give me suggestions as to how to bring it back to life? Thanks, Marian
