A friend has 3 mountain laurel bushes in Zone 5b which he planted in the fall of 2009. All three are suffering from the same affliction: within about 3 weeks time between May 23rd and June 11th, they went from looking fabulous and healthy - about to bloom -- to the leaves turning uniformly brown and the bush looking terrible! He was out of town, but a local nursery claims there was some cold weather during this time. Otherwise, they couldn't help us diagnose the problem.
Here is a picture of the front side of a leaf:
unhealthy Mountain Laurel - please advise!
It does look like a burn and possibly freeze burn.
Thanks for your input, Growin. Do you think the bushes can recover? Anything we should do for them?

I agree with "Growin" about burn is it possible that it is either salt burn or burn from too much fertiliser. If salt burn it could be because the tree roots have reached a hidden saline water table or if the land was filled they may have reached the old soil which could be saline.

I'd just wait it out and see if it survives or dies. It might send out a re-flush of new foliage.
