Most workers are high school graduates, although a high school diploma is not necessary for some jobs. Experience can be attained through home gardening or working in a nursery, a sod production operation, or a tree service. High school students may gain experience in the Future Farmers of America and other associations. There are no national standards for gardeners and groundskeepers, but most States require certification for workers who apply pesticides. Certification requirements vary, but usually include passing a test on the safe use and disposal of insecticides, herbicides, and fungicides.
Employers prefer applicants with a good driving record and some experience driving a truck.
Workers who deal directly with customers must get along well with people. Employers also look for responsible, self-motivated individuals, since many gardeners and groundskeepers work with little supervision. Courses in agronomy, horticulture, and botany are helpful for advancement. Courses include equipment use and care, landscape design, plant biology, and irrigation. There are cooperative education programs in which students work alternate semesters or quarters for a lawn care or landscape contractor.
