You may not be aware of automatic watering systems, they are a simple network of tubes and drippers that run around the garden and allow plants to be watered in a simple and efficient way. They are exempt from the hose pipe ban where the system is
controlled by a timer, has a pressure regulator fitted and the water is dispersed by small drippers.
These systems are becoming very common as they allow you to water your plants easily once set up. You often see these systems in commercial properties such as pubs and restaurants where they are used to water beds and hanging baskets.
You can get basic kits that contain all of the components to get you started and they can be fitted at home without professional help.
