i was just given a begonia (angelwing I think) that has been EXTREMELY overwatered. in november this plant had beautiful foilage and now has about 15 leaves on a 4ft plant. the plant has not been watered for about 6 weeks but they did not empty the drip pan so it sat in STINKY water at least that long.

what should I do... repot with dry soil, wait it out, prune it, i need serious plant help. too cold to put it outside (freezing tonight in Georgia). I really want to save it since it is my recently passed Grandma's plant.

thanks!
