Little time for gardening then consider low maintenance areas that use ground suppressing membrane, crushed slate, stone chipping's, pebbles and gravel.
All these materials suppress weed growth while allowing water to drain away. Using these materials in combination with smaller planting areas and planters and pots still allows planting but on a low time / low maintenance scale.
Paved foot paths combined with gravel beds and narrow planted borders produce a low maintenance garden or seating area. A modern alternative is combining natural stone paving, artificial grass and raised beds constructed from timber sleepers for planting.
