Long story short but I wasn't able to plant my oleander - and now it's really hot (zone 7b) and still in the pot. It's dying. What should I do now? It acts like the sun is too much for it so I moved it to part shade. I don't know if it's sickly because it was not transferred out of the pot (which was never my original intention). Now, I'm concerned about replanting it in a bigger pot or in my yard because it's so hot and I've heard not to transplant in hot weather.
