Rhode Island Certified Horticulturist Program
What is RI•CH?
An Integrated Foundation of Knowledge
The Rhode Island Certified Horticulturist Program, or RI•CH for short, provides working horticulturists with best horticultural practices such as planting and pruning while also emphasizing practices that will conserve and protect our soils and water. The RI•CH course and the Manual it is based on serve as an integrated foundation of knowledge from across a variety of sectors of our industry. The course and Manual are interdisciplinary, not only because the green industry is interdisciplinary, but because working with plants and the land is interdisciplinary. Because of this, it is important that professional horticulturists possess a broad and integrated foundation of knowledge, providing a common standard of practice across the industry. By becoming a Rhode Island Certified Horticulturist, you will contribute to the enrichment and professionalism of the green industry and raise the bar for what it means to take care of our beautiful state.
The RI•CH program has been revised and updated and has a new format.
RI•CH is a program of the Rhode Island Nursery and Landscape Association (RINLA). The RI•CH certificate is earned by green industry professionals who pass an examination based on plant identification and the contents of The RI•CH Training Manual and RI•CH instructional course. Rhode Island Certified Horticulturists then maintain their certification by earning 5 re-certification credits of continuing education and service each year.
RI•CH promotes the highest ethical standards, increased professional skills, and continuing education in horticulture through current research-based horticultural information and practices.
If you are a working professional in the green industry, becoming a Rhode Island Certified Horticulturist may be the right next step for you to develop your career.
