All my hanging baskets or hanging pots do hold 5 plants. They will be all right, but they must be watered every day when the weather is hot and must be fed every week at least with a general purpose feed. I don't know what is available over there, but I use either Chempak or miracle grow. I think you also mentioned that we have mild weather here so don't need winter protection. Don't you believe it. At the moment here it's just above freezing, and they are forecasting a severe frost over the next few nights and snow likely tomorrow, although not much. All my plants are put away in the greenhouse for the winter,
