The answer to 'how to maintain landscaping' is to develop a regular maintenance routine that includes mowing, edging, pruning, and fertilizing your lawn and plants. This will keep your landscaping looking its best and prevent problems from developing.
Start by mowing your lawn on a consistent schedule, usually once a week during the growing season. Be sure to keep your mower blades sharp and adjust the height to remove no more than one-third of the grass blade at a time. Edge along sidewalks, driveways, and garden beds to maintain a clean, crisp look. Prune shrubs and trees regularly to remove dead or damaged branches and encourage healthy growth. Finally, apply fertilizer to your lawn and garden beds 1-2 times per year to provide essential nutrients.
