Good morning, Jessica.
I would like to balance out a garden that I made a few years ago. In order to do so, I would need to move some 2- 3-foot hydrangeas. It is too late? I see that they have already begun to produce leaves. -- Ian
The best time to transplant hydrangeas is when they are dormant, after the leaves have fallen in fall or during winter. You can move them now, but you'll have to give it some TLC to minimize stress and ensure it thrives. Naturally, dig up as much of the roots as possible. If you have Macryphyllas (big leaf hydrangeas), the root system can be pretty big. Incorporate plenty of compost into the backfill when re-planting, and water regularly throughout the spring, summer and fall, but remember they don't like soggy soil, so don't overdo it.
