Horticulture involves the use of different types of machinery, such as tractors, vertical cutters, mowers and weed cutters, and interviewers will likely test your knowledge of working with these machines. For example, they might ask you to discuss the tools you use to control thatching. In response, you could talk about vertical cutters and power rakes. The hiring managers also might want to be sure that you can use the tools safely and deal with any problems that might arise. At this point, you'd discuss maintenance schedules for your equipment.
