Enrol for this course

Understanding Applied Plant Propagation  is the fourth unit of the Level 3 Plant Growth Certificate.

The RHS have set a deadline of March 31 2023 for anyone wishing to embark on study for this Certificate, which is part of the suite of Level 3 qualifications which will be  replaced in September 2023 by a new RHS Level 3 Diploma.  There is no transition for individual units, so if you have already started the Plant Growth Certificate you have until the February 2025 exam round to complete it. This means you have only June 2023, Feb and June  2024 and Feb 2025 to take or retake exam units.

Completing both the current theory Certificates plus the current Practical in 2022-23 or the new Practical Certificate in 2023-4 will allow you to achieve the current RHS Level 3 Diploma before the cut-off for transitions in July 2025. You can read about the transition arrangements and how some parts of the 'New' qualifications can help you complete the 'Old' Diploma on the RHS website here or download their Level 3 transition document here.

Units 2, 3 and 4 of the Level 3 Plant Growth Certificate will remain available to you to purchase if you have already begun your studies before the RHS deadline.

What will I study?

This fourth unit looks at the relevance of plant anatomy and physiology to propagation by seeds, spores and vegetative means, and at the management of propagation equipment and aftercare.

It builds on the basics of RHS level 2 ‘Understanding Plant Propagation’.

How is it delivered and assessed?

Online learning gives you flexible study - you can log in to your 'virtual classroom' for each unit:

Download notes and presentations to read on or offline, or print them out if you prefer
View interactive materials and 'self-test' quizzes online
Contact your course tutor using the internal messaging system
Upload practice exam papers and questions, and your revision workbook for feedback and support
Keep in touch with other students on your course through the online forum
Get updates and reminders about exam deadlines.

What qualification will I get?

When you have passed exams in all the units, the Royal Horticultural Society will award a Level 3 Certificate in the Principles of Plant Growth, Health and Applied Propagation.

If you successfully complete the other theory Certificate, and the RHS Level 3 Practical Certificate in Horticulture as well, the RHS will award you a Level 3 Diploma in the Principles and Practices of Horticulture.

Your enrolment gives you online access and tutor support until the final examinations which the RHS hold for this form of the Certificate.

What is the cost and venue(s)?

Study at home, or whenever and wherever it suits you. You can download most of the course materials, print them out if you prefer, or take them with you on a tablet on your daily commute.

You can buy each unit separately at £100.

These course costs do not include RHS examination fees  (currently about £30 per unit, the RHS increase  the price each year in September so please consult the booking page for up to date prices.). 

These fees are paid to the RHS by the Centre where you choose to take your exams, and while we offer our students the facility to take exams at our Ryton centre, this may not be the most convenient location for you. You can arrange to take examinations at any Centre which offers your specific exam and which will accept an external candidate. The RHS website gives guidance on finding an exam centre. You can also choose to take your exams online using your own computer and remote invigilation - for this you need to contact the RHS direct on
