An entrepreneur is interested in starting a plant nursery. In researching options, she has uncovered several important aspects of the area in which she would like to establish her business. First, there are 15 landscape businesses registered within the county.
Second, there are three retail nurseries that sell directly to the public and none that sell only to businesses purchasing large quantities.
