Maintainable
It has to work
Maintainability is closely related to functionality and ideally will be nearly as prominent in design consideration. A functional design can be easily used by people and a maintainable design is easy for people to care for.
A sustainable landscape will, by its very nature, be more easily maintainable. Less trimming is required and also less fertilizer, pesticide, equipment and irrigation will be needed.
GOOD MAINTAINABLE DESIGNS
Avoid or eliminate designs like hedges that require regular shaping.
Reduce string trimming by using edging and borders sparingly, or not at all.
Don’t use design features that are too narrow for individuals or equipment.
Choose plants that can reach their full, mature size in the space allowed.
