Basically we use two forms for landscape design, either natural stones or concrete, So what will be easy to maintain for your residential landscape design?
If you can use natural stone effectively and it serves the structural purpose of your project, the stone is my preference in terms of maintenance. Generally speaking, I think both will be fine. But concrete, if done incorrectly can crack over time, and lose its luster. I think the natural stone provides an aesthetic look that improves with age, and should need little to no maintenance. Natural stone will be more cost and work on the front end generally speaking though.
Any landscape with higher percentage of hardscape is always going to be lower maintenance and easier to maintain.
Whatever material you choose it has to be installed properly, everything is depending on the preparation of the setting bed and properly compacted subgrade. Drainage is also critical.
In a pedestrian setting, natural stone is preferable, but expensive. If a stone breaks it can be removed and replaced. Monolithic concrete slabs and stamped concrete slabs tend to crack and require large areas to be replaced. Installation and placement of control/construction/isolation joints is critical with concrete installations. Concrete pavement on the other hand offers the convenience of being able to remove a few damaged pavers as opposed to a large area. Concrete is also a fraction of the cost.
Cost tends to dictate that concrete be used in vehicular applications. While note as beautiful as stone, concrete unit pavement is a more aesthetically pleasing alternative and cost effective.
