"Nursery" means an area where trees, shrubs or plants are grown for transplanting, for use as stocks for budding and grafting, or for sale. For a primary use to qualify as a nursery, at least 50 percent of the area must be used for growing trees, shrubs, or plants, and incidental sales of accessories and materials other than trees, shrubs, and plants must be less than 25 percent of total sales and fees generated by the nursery.
