About the course

The RHS Certificate in the Principles of Garden Planning, Establishment and Maintenance is the 2nd part of The Principles of Horticulture Level 2 which is recognised within the industry and students who achieve it will be well placed to progress onto further courses or into employment.

This is the last chance to take this course as the RHS  has now started a new Principles course in September 2022.

The course is also ideal for the dedicated amateur gardener who wishes to extend their knowledge and perhaps achieve a nationally recognised qualification.

RHS Level 2 qualifications are for those wanting a route into the horticultural profession, to support career development for those already working in horticulture or to provide a foundation for further learning or training.

There is no pre-requisite knowledge needed for entry to the qualification.

Achievement on this course is through nationally set written examinations; the level of knowledge expected is equivalent to a good level of pass in a GCSE science subject. We do recommend that you take the exams, but we do have students who decide to enjoy this purely as a leisure course.

Examination costs are included in course fees, as are revision sessions to prepare you for each exam.

What you will learn

The weekly session will include plant identifications as well as classroom-based theory. Comprehensive notes will be provided. Students will be encouraged to take part in weekly practical demonstrations, and benefit from  designated facilities on our commercial nursery and working in our display gardens.

Course content:

  • Plant identification
  • Theory, with full well-written handouts provided
  • Practical demonstrations
