RHS Certificate Practical Horticulture Level 3

Course overview

Qualification is subject to centre approval.


Those involved in the field of Garden and Landscape Maintenance have to be able to apply the principles of horticultural science, seek out best practices, select techniques which are cost-effective, embrace sustainability, ensure biosecurity, and comply with current legislation as they develop the gardens and landscapes under their care.


The purpose and content of the Level 3 qualification supports specialist/industry-specific pathways informed by the findings of the Ornamental Horticultural Round Table Group (OHRG). It is aimed at those progressing in horticultural roles or having a specialist personal interest in the supervision and development of gardens and landscapes, meeting the needs of amateur gardeners and professional horticulturists alike. It also provides learners the opportunity for personal development, including the changing of careers and engagement in their learning. It offers an opportunity to develop transferable skills such as problem-solving, implementing management plans/programmes, and communication as part of their applied learning.


Merrist Wood has developed a considerable reputation for horticulture and for its award-winning gardens designed and built at RHS Flower Shows. The diverse range of plants in the College’s 400-acre estate, together with purpose-designed buildings, including lecture rooms, laboratories, library facilities, and computer suites, all provide an ideal environment for horticulture students.
