I got a gumpo azalea actually got a couple. This one is failing to thrive. The apex leave tips are turning brown, very little new growth on the lower portion of the tree. I think this may be an issue with root rot. It needs a repot. The soil it tight and don't drain well at all. I have slacked off on watering. This time of year is it ok to repot. I know early spring would be better. Any advice. Pics to come.
