I'm always seeing in magazines small citrus trees in pots. Does anyone know what variety of lemon would be best for this and how big exactly does the pot need to be? Like, would a half whiskey barrel be sufficient? I would love a lemon tree but I don't have many spots for more fruit trees and my kids really want an apple and a peach so I was hoping I could do a potted lemon. I had planted a "dwarf" lemon tree at our previous house that kept growing taller then the house and the lemons were gigantic. I don't know if it didn't stay small because it was in the ground or if maybe there aren't really lemon trees that stay small, lol.
