The amount of maintenance needed depends on the type of landscaping you install. Plants may need supplemental irrigation, weeding, fertilizing and pruning. Native plants often require less maintenance because they thrive well in the environment. Wood structures, like decks and fences, benefit from occasional power washing and sealing or painting. Pavers, bricks and stones also need occasional cleaning to look attractive. Weeds also tend to grow up between the bricks, so weed removal is a maintenance consideration.
