The document discusses using horticulturists to revitalize interest in public gardens and horticulture. It proposes having horticulturists give guided tours, write content for the website and social media, and create audio tours to educate visitors about plant collections and the work that goes into maintaining them. This approach could help connect the public to the horticultural field and enhance the visitor experience, but challenges include finding time for horticulturists to do this and developing engaging formats that keep up with changing gardens.
