Mine is in a ten gallon pot, is 8 ft tall, and fruits like crazy. It is in my greenhouse in about half shade, and gets Osmocote Plus, and "regular" or "bloom" Miracle Gro, depending on whether it is blooming or not. I use a fertilizer that feeds directly because I feel like I can't get a good micro-biome going in "soilless" potting medium. I do occasionally dump in some worm castings, and my quail poop in the pots a lot...
Cheers,
Carolyn
