I do my best to keep my "Momma" fiddle moist at all times. She is 25 yrs. old and has been in the same 24-28" pot for the last ten years. I know she is terribly root-bound but she seems to be a happy plant. I also fertilize her regularly but at 1/2 the recommended dilution rate. She might get fertilized weekly.........weakly. Since I grow so many plants (800-1000), and the vast majority are outside from April till November, I am always watering/fertilizing something. I walk around with a hose that has a gentle "rain" end and just hose my plants, leaves and all. Since my fiddle is so root-bound, I could not overwater her if I watered her heavily every day. Beside, as long as you have premium potting media that drains extremely well, and excess water can run out of the drainage holes, I don't think anyone should have fear of overwatering. With their huge leaves that transpire a ton of water daily, these plants are heavy drinkers.
