When you want to upgrade your backyard, you typically need a couple different experts: a designer and an installer. An experienced designer has a knack for where things should go and has spent years perfecting backyards of all layouts imaginable. They’re also great at knowing what kind of plants will grow well in your yard.
Meanwhile, an installer is good at buying, installing and maintaining those plants so they don’t die. However, installers are only executing someone else’s vision, not devising a grand and beautiful layout. In this sense, upgrading your backyard is like doing a major remodel of your home—you need an architect or designer to help you make all of the decisions and then a contractor to build and install everything.
