Answer: I'm afraid that plants growing in containers dry out faster than the same plants growing in the ground so hauling water on a daily basis is going to be required to keep your plants healthy and happy. A drip irrigation system would help but I don't think you can install one on a patio without having the lines become a tripping hazard for anyone walking on the patio. Perhaps you can park a cart on the patio that holds a drum of water and just move the cart from plant to plant to water? That's how they do it in big resorts and hotels.
