Rhodedendron problems

Hi all.
New to the forum. Thanks for having me
Having a few problems with my rhodedendrons this year...
I have 2 dwarf rhodies that have been in the ground and I've just relocated them to some planters I made. The back sides of them are really sticky and lacking any foliage. Im guessing due to lack of sun as they've been against the fence. Is there anything I can do to revive them and make them more bushy? (See the first 2 pics).

I have 2 others...one I think is a lost cause where the other is still pretty strong but the leaves are starting to curl and go crispy.
(See pics 3 and 4).
Any help would be much appreciated.
Many thanks!

 

Welcome to the forum. The last two look like a lack of water. I would think the first two will come good as Rhododendrons are pretty persistent. They grow as weeds on the West coast of Scotland.
I lifted an old Rhodie leaving half its roots behind (I had to use a crowbar to get it out). I scraped a hole in the ground and stuck it in and it is producing fresh shoots after a few weeks

 

@Sparkoman85 Whereabouts are you based?
Are they planted in ericaceous compost or garden soil?
I would keep them well watered, stand them somewhere shady and out of the wind, cross my fingers and see what happens.
Once they are growing again you can think about getting them to bush out.
