Landscaping is a field that encompasses a great many possible careers. Everything from trimming trees and planting flowers, to building garden structures and installing irrigation, just to name a few. Some landscapers might even work on a larger scale, planning and designing a golf course, for example, would be a job for a landscape architect. Clients in need of landscaping for their new pool or patio, or needing a retaining wall built, will be in touch with a trusted landscaping company. Large corporations have company grounds to be maintained, schools and universities have campus grounds to keep, cities and towns have public parks that need maintenance and improvements, zoos and theme parks need landscape design solutions too; all of these are potential clients or employers for a landscaper. On a smaller scale, many landscapers earn a living planting seasonal flowers and trimming trees and shrubs. This sort of work doesn't require much equipment or training, so it can be a good stepping stone to a career change, providing an opportunity to get one's feet wet without necessarily quitting the day job.
