As long root ball mainly intact could do ok. since spring , transplanting hopefully will not be too stressful.

where are you ...

probably depends on how soon the heat of summer hits... can it regenerate the root mass... in time for it to be able to pump the water it needs ...

keep it deeply watered.. and well mulched ...

if you note it drooping as the heat rises... perhaps you could figure out how to add temporary shade ....

if you note significant drooping too soon.. you might forego bloom for one season .... or reduce it ...

regardless.. you had to do.. what you did ...so dont worry about it ...

I also would consider temporary shade when it leafs out, perhaps a sheet hung vertically off poles on the south and west sides. Another option is to take some cuttings to start a new plant just in case.

Probably easier to start new plants from cuttings than digging and moving a big plant (in case you do this in the future). I did that with Hydrangea PG and Viburnum Opulus and now that I have 4 of the PG and 3 of the Viburnum established, the mother plants can be cut down or allowed to survive the best they can (until I need their space).

The only downside to this method is you will have small plants for a few years (no instant gratification although two of the viburnums bloomed this spring and the hydrangea might - still a little early to tell).

Good luck with those hydrangea PG blooms this summer. Hope you get at least one!

I had to move a huge White Diamond hydrangea, which involved absolutely hacking at the thick established roots. It was only just starting to bud at the time and still leafed out with no trouble in its new home. I was sure I had killed the darn thing, but it never missed a beat.

I moved some sort of pani from along the house after the builders cut it off at the stump. I kept it from sprouting again for the next year or two then decided to move it. Chopped some of the main roots while digging it bc they went so deep.

Planted it across the yard. End of August 2017

It grew profusely from the existing shoots.

I did some pruning on it this spring to get a better shape but no new pics yet. You'll have little trouble with yours if it's anywhere near as tough as this one. :-)

Wow! thanks!!
