I transplanted these Apple Betty to a 10 gallon container, usually I'd start smaller like a 1 gallon or 3 gallon and work my way up to 10 gallon but I tried to just go with it. As long as your watering practices have discipline, it's fine to transplant into a bigger container. Mixed with Gaia Green All-Purpose and Wiggly Worm castings, 1/4 cup.
