Certified ExpertA.Unfortunately, your photo did not come through. It does sound a bit like they may be receiving too much sun! They are better suited for shady spot.
In the meantime, this article will help you to care for the shrubs:

Certified ExpertA.More commonly known as the Vireya, this Rhododendron type is native to tropical areas. It will not survive the winter outdoors. It will need to come inside when the temperatures start to get, even, remotely chilly.
Since they aren't exactly common, there is not a whole lot of literature on them. You should treat it as a Rhododendron with the exception of its cold tolerance.

September 19, 2020Q.Yellow leaf drop
Hi, my rhododendrons, but mainly the 8 year old one is dropping leaves that are yellow, some of the branches are yellow too. I fed it in early spring and given a tonic at least 3 times during the summer, the last time being about 2 months ago, but it has been like this the whole summer and now as the weather is cooling overnight, it appears worse. Also, all the others are experiencing the same including my azalea. I believe when they require water they also have yellowing leaves, so I have been watering as required. Also, there does appear to a mild weevil attack going on , but I used a weevil killer for this, although I am not sure if they have been eradicated. Is there anything else I can do before winter.? Thank you in advance.

Certified ExpertA.It sounds like your plants have a case of chlorosis, or iron deficiency. Amending the soil with sulfur and providing an iron fertilizer will help correct the problem. This applies to your azalea, as well.
