Can you transplant rhododendrons in June in northeast if so how?

I agree with Molly. Wait until Fall. If you must move them now, make sure you get enough of a root ball (rhodies roots aren't very deep, most are close to the surface, so go wide) and re plant immediately. Mulch well, and water heavily. I hope you are moving them to a shady spot :-)

Transplanting should be done only when plants are dormant. If they are dormant they won't even notice that they've been moved.





When you dig up a plant, roots are bound to be severed. If the plant is actively growing, having its roots severed will send it into shock and you risk losing the plant. It's like performing surgery on someone who's awake. So do your transplanting in the late fall through early spring while the plants are dormant.





My neighbors across the street just transplanted about a dozen Arborvitae a couple weeks ago and now they're all dying. That was a lot of wasted effort and it will cost a pretty penny to replace those fully-grown shrubs.
Reply:I would wait until the fall, but if you need to move them wait until they are done blooming. Once you get them in the ground water very well.
