Both of these have contributed to a demand for plants and trees. This is a small occupation, so jobs are rare. Most people who become managers are promoted from within the nursery. Specialty growers need to have knowledge of plant culture, market conditions, and environmental-control systems and structures. There is no data available on specific education or training programs for nursery workers.
Some states require licenses for people who apply pesticides.
Requirements vary by state. In general, those who apply pesticides must be at least 18 years old and pass a written exam. Some states require that pesticide applicators take a training course of 16 hours or more. In most states, pesticide applicators must renew their licenses every three years. Workers may need to take courses in order to have their licenses renewed.
