Question
I have a tree hydrangea that has been established for 3 or maybe 4 years. We are going to enlarge our deck which will call for relocating the tree hydrangea. How is the best way to do this, and where will it thrive best?   Thank you very much.

Answer
Hi Judy,
Thanx for your question.  I would trim the shrub back to make it easier to handle but it's not necessary.  Then digout a foot from the shrub and dig deeply all around until you are able to loosen the rootball.  Yes, you will cut through some of the roots but it shouldn't harm a large plant.  If you live in a place with really hot summers, I would plant the shrub somewhere where it will get relief from the afternoon sun but gets full morning and full evening sun.  If you're in zones that don't get really hot, anywhere in full sun should be ok.  You should dig a hole slightly larger than the whole from where the shrub came and set the rootball in the hole and then cover with the dug up soil.  Soak the planting well and then soak it once a week.  Side dress the plant with well-composted manure and mulch it a few inches was straw or pine needles or leaves to help retain moisture.  I hope this helps.
