I'm definitely on Team Ground. I don't need to water very often, don't have an irrigation system, and rarely use sprinklers -- so anything in a container usually dies from thirst. That said, I do have a couple of self-watering planters on the back deck and try to remember to keep their reservoirs filled up, with some success. Most recently, I've been using grasses, and I have a Harry Lauder in one, so the watering needs are not as crucial. Seems to work for me. Everything else is in the ground.
