If you can turn it, is it still a TREE? Actually I have 10 to 15 smart pots, 15 to 30 gallon, that I use to grow mothers and breeders and I have always turned them but not on any set schedule. My grow pots vary from 300 gallon smart pots to home made 8 to 10 foot fence or chicken wire and road fabric walls. The bigger the pot... The bigger the plant.
