The cool, cloudy weather this week will help your plant to recover, but if you can get a piece of shade cloth and rig it up over it, for maybe the next month or two, until it can get its roots out into the soil, that will also help a lot.
This is a pretty tough time of year to plant a big plant like that. Before all this rain made it onshore, we had some pretty hot, dry weather and almost a full days's bright Florida sun is really hard for a potted plant to withstand.
Have you been watering it every day in the mornings, so that it's well hydrated for the day's heat?
