'Anna Kruschke' is a hybrid rhododendron, not an azalea, and will get to be a pretty big one at that!

The plant looks like it is lacking adequate water and may be planted too deeply. Photos are not clear enough to tell but there is a lot of very limp stems and dead material in the first photo. I'd suspect it is on its way out :-(

Thanks for your reply. It’s been very rainy here lately, and when it doesn’t rain we water it every 4 days with a sprinkler.

is there anything that can be done at this point to save it?

You might as well try pruning it off low down and see if new growth appears. The alternative is to take it out and start over,

what did the root ball look like when you pulled it out of the pot.. did you do any root surgery ... was it necessary ...

its a sever watering issue ... on only this one.. go figure ... but not uncommon ... too much.. or too little is what we need to figure out ...

i might be tempted to pull it out and find out what is going on underground.. where the watering issue is ..

proper watering of shrubs and trees.. rarely involves a sprinkler.. they need deep watering thru the root mass planted.. and then near drying ... this early in the year.. i cant believe much of anything needs watering every 4 days ... if your watered deeply at planting ... and if its been raining .. but im not where you are ....

before you dig it completely out ... take a hand trowel.. and dig a couple 3 inch holes around the gob planted.. AND FIND OUT ABOUT moisture at root depth.. adjust watering accordingly ...

and report back what you find ...
