A level 2 qualification from the RHS can be the first step in changing to a career in horticulture. It is an accepted route into the horticultural profession for National Trust and many other employers. This is also an ideal course for adult beginners or keen gardeners who want to broaden their knowledge. 

This course introduces you to botanical names and the terminology of horticulture, and to the basic science behind plant growth which underlies how you can keep plants healthy and propagate them; it  also gives you an outline of the relationship between plants and the soil and how nutrients are supplied.  

Note: This course can also be studied at our Ryton and Bampton centres or as an online course; see the course tiles below for details.

What will I study?

Each RHS Certificate is made up of four individual units: you can work through them in turn, or you can just study single units that interest you.

  • Plant Classification, Structure and Function
  • Plant Nutrition and the Root Environment
  • Maintaining Plant Health
  • Understanding Plant Propagation

How is it delivered and assessed?

Correspondence course 

We will send you full-colour printed course materials, plus a revision workbook test paper,  for each unit. Your tutor can be contacted via email to support you in your studies, marking your revision workbook and mock examination papers to give you feedback and help you to prepare for examinations. You will also have access to the online classroom as a backup, to get reminders about examinations and to network with other students.


The theory Certificates are assessed by national exams set by the RHS each year in February and June. Each unit has its own  short written exam.

We do not enter you for the examinations, but we will make you aware through the online classroom of exam dates and deadlines and your tutor will give you guidance on whether you are ready to take the exams. 

What qualification will I get?

When you have passed exams in all the units, the Royal Horticultural Society will award a Level 2 Certificate in the Principles of Plant Growth, Propagation and Development.

If you successfully complete the other theory Certificate, you will be awarded the RHS Level 2 Certificate in the Principles of Horticulture; and when you successfully complete the RHS Level 2 Practical Certificate in Horticulture as well, the RHS will award you a Level 2 Diploma in the Principles and Practices of Horticulture.

Note: it is not compulsory to take examinations if you are following the course for your own interest.  However if you want a Certificate to demonstrate that you have followed the course to a successful completion you will need to enter and pass the examinations. THe RHS will no longer  allow to us to provide any evidence that you have studied the course without taking examinations.

What is the cost and venue(s)?

Study at home, or whenever and wherever it suits you, with your full colour printed course books.

Individual units are  £126 each (£105 + VAT) or the full Certificate is  £444 (£370 + VAT)

These course costs do not include RHS examination fees  (currently £17 per unit). 

These 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 and North Moreton, these may not be the most convenient locations 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.

What is the enrolment process?

You can enrol and buy your chosen units on the website using PayPal.

For online courses, your username and password will be emailed to you within three working days; correspondence materials will be sent out within a week. 

We use the information you give us on PayPal to set up your enrolment  - if you buy a course for someone else, or your PayPal uses an old email address, please contact us. 


What else do I need to know?

There is no compulsory course work, but you will be given the opportunity to try practice examination questions if you are going to take the examinations.

Our candidates enjoy a high level of success in RHS examinations, with over 90% passing on the first attempt and approximately half of those, passing with commendation (that means they achieve 70% or more in the exam).

What can I do after completing this course?

You can go on to study the second theory Certificate, The RHS Level 2 Certificate in Garden Planning, Establishment and Maintenance. Alternatively, you could undertake the RHS Level 2 Practical Certificate in Horticulture, which is assessed rather than examination- based qualification.

An RHS Level 2 qualification is well respected in the horticultural industry and can be the first step in changing to a career in horticulture. It is an accepted route into the horticultural profession for National Trust and many other employers.

After completing your studies at Level 2 you can progress on to an RHS Level 3 qualification.
