Lazy Gardening: Reduce lawn space
While lawn space requires regular care, it does not deliver the same joy as flowers or other plants. Reducing the size of that lawn space frees up effort and time for other forms of gardening. This may sound odd, but reducing lawn space (and the typical straight line and 90-degree corner boundaries) can create interesting nooks and crannies that will make your yard seem larger.
I've used areas of wood bark mulch atop layers of cardboard and newspaper, with metal garden edging as a border. The cardboard and newspaper layers keep weeds from sprouting amid the mulch. Those layers naturally disintegrate during the course of several years, but replacing them simply requires using materials that would otherwise end up in a recycling center. These mulched-covered areas were created during a four-year span.
