The RHS (Level 2) Certificate is well recognised within the industry; students who achieve it will be well placed to progress onto further courses or into employment. This course is over 100 years old and still as popular as ever. The course is also ideal for the dedicated amateur gardener who wishes to extend their knowledge and perhaps achieve a nationally recognised qualification.

The Certificate in the Principles of Horticulture is a broad-ranging course taught 3 hours a week over 6 terms and covers the full spectrum of horticultural subjects. It is ideal for beginners or for those with some experience.  'Level 2' compares this course to other qualifications; the RHS does not offer a level 1 theory course.

Achievement on this course is through nationally set written examinations taken in February and June 2021 (Year 1) and February and June 2022 (Year 2) and the level of knowledge expected is equivalent to a good level of pass in a GCSE science subject.

Who can apply?
Entry onto this course is open to anyone who has a genuine interest in horticulture – no formal qualification is necessary.

What will I 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.

The following outline is intended only for general guidance on the range of subjects to be studied:

Year 1: Principles of Plant Growth, Propagation and Development

  • Plant Classification, Structure and Function

What should I bring each week?
Writing equipment is advisable to enable you to take down any extra notes and your weekly homework. Secateurs and gloves will be required for most practical’s. You will be advised of any extra tools required for practical’s a week in advance. Sensible outdoor clothing and strong outdoor shoes, preferably steel toe-capped boots, should be brought in for the practical session each week.

The course tutor, Tessa Allen, has taught horticulture for over 31 years and the RHS Certificate in the Principles of Horticulture for the last 21 years. Throughout, Tessa has had a high achievement and retention rate, which she puts down to the friendly but organised classroom atmosphere.
