Hello. We are having a problem with some newly planted Azalea Herbert. They were purchased and put in the ground in early April. They looked healthy and bloomed profusely. Then after blooming some of the leaves started to turn brown and shrivel up and fall off and then the branches died. We had 6 altogether -- 2 of them are almost completely dead, another 2 are about 50% dead (although they have some new growth coming in) and the other 2 are mostly okay but have some leaves that are starting to turn brown. We examined the trunk and the branches but didn't notice anything unusual based on photos of various maladies we found online (phomopsis, cold injury, etc.). We were thinking of digging one up and checking out the roots but weren't sure exactly what to look for. I've attached a photo of one of the two that is just about dead. Does anyone have suggestions for what to do? Should we remove the ones that are dead to prevent spread of potential disease? Or just cut them back and see what happens in the spring? Any advice would be greatly appreciated.
