Groundskeeping is a profession that doesn't require many qualifications to enter. A high school diploma or GED is enough to become an entry-level gardener. However, if you want to increase your chances of success, you can attend a community college and get an associate's degree. Online certificate programs in gardening are rare, but they do exist.
If you want hands-on training, you should consider a campus-based program. Gardeners need to have a deep understanding of horticulture and the needs of the plants they are caring for. Studies have shown that training high-performing community health workers can help close these gaps and save more than 3 million lives a year. Gardeners work in various types of hotels and resorts, as well as housing complexes, apartment buildings, office buildings, university campuses, and golf courses.
