Hi -
From experience,you can grow these anywhere, really - I have a garden with dogs, so nothing can be low level - I have had success with pots bags and baskets, up to and including beefsteak tomatoes and all my veg are in bags, pots or planters, with the same effect. If they are started inside and well established, they will grow happily in whatever you choose to grow them in. They are quite tough really! Hope this helps! Jules
