Hi, are you talking about native azaleas or the evergreen asian azaleas? Apparently the asian ones can take some sun (I've seen several posts to that effect, people talking about how much sun they put them in).

I have native azaleas and I find they can take about 6 hours of sun, preferably morning sun to early afternoon (1 pm or so). In fact, they bloom best when given up to 6 hours of sun. So I would suggest if you can protect them from the post-1 pm sun, then go for it. Be sure to give them plenty of mulch (shredded leaves, pine bark) to keep them roots cool and make sure they get adequate water in the first year. Plant them a little high in a hole that has been lightly amended with soil condition (composted pine bark).

Not sure how much sun the area gets? I read a great idea. On a day when you are home, go outside every hour and if the area you are watching has sun, then plant a flag or other marker. At the end of the day, count how many markers you placed and that is the number of hours of sun it gets. Have to do this on a sunny day, of course.

If you are looking to buy some native azaleas, there will be a great selection at the GNPS native plant sale in Piedmont park in April.

Thanks esh_ga
I am considering the native azaleas in the future but really asking for experiences with the Encore brand. Seems like folks are planting these in areas that get afternoon sun.
thanks for the information!
