This all depends on the type of plants you choose. If you pick low-maintenance plants you won’t have much to do, except watering them, of course.

On the whole, it’s way easier to take care of a living wall than of a real garden. But you will have to take care when you water the plants. Too much water falling on the wall might lead to mildew and if the walled garden is somewhere inside the house it might ruin the floor. Explore our list of safe and creative wall ideas for gardens.
