This is unfortunate. If the plant is in a pot, you could presumably take it in out of the rain (don’t mean to be obvious). If it’s in the ground, you could conceivable dig it up and transplant it into a pot for a while, but be aware that the shock, so to speak, of the move could slow its recovery only because it will take time for it to adjust. Finally, it could be a sign that your soil does not drain as well as it might—although 6 inches could inundate many kinds of soil. Other than that, you can let nature take it’s course.
