Okay, so I took the plunge and bought a 5 gallon nuccio's gem. "Gemmy" is about 5 ft tall or so. What do I do now? I've heard that camellias have shallow roots, so do I need a shallower pot than usual? What kind of potting mix do I use? What should I put in the bottom of the pot (ie, shards, etc.)? Do I water so that the soil stays slightly damp? When do I feed him???
