I planted a new Charm hydrangea where it will get afternoon sun. I have now realized that it should have been in the morning sun and afternoon shade. Should I move it? I planted it in Aug. and it is now Sept. In Kemptville, Ontario area.

However, if you notice that it is not thriving or if you simply feel better by moving it elsewhere, then go ahead and do so. Just make sure that you get as much roots and soil as possible.
