This is one of a new generation of certificates launched by the Royal Horticultural Society in 2010 to replace older qualifications.

This vocationally-oriented course is designed to lay a foundation for a long-term career in horticulture by assessing knowledge of the principles underpinning horticultural practices. It supports the career development of those already working in horticulture and is best undertaken by those with training to Level II.

The course consists of approximately 200 hours of study in 15 lessons. It covers the four units set by the RHS as follows:

  1. Plant taxonomy, structure and function
  2. The root environment, plant nutrition and growing systems
  3. The management of plant health
  4. Understanding applied plant propagation

The second part of the RHS Level III Certificate in Horticulture can be found here.

To obtain the RHS Level III Certificate awarded by the RHS in England, the student needs to sit and pass written exams conducted under supervision and assessed by the RHS. Exams can be arranged to be sat anywhere in the world and are offered twice annually; in February and June.

A separate fee applies for exams; set by and paid to the RHS. A network of exam centres are located across the UK for students located in the UK. For students located elsewhere; a provision is made for exams to be conducted "under arrangements for exceptional supervision".

Those who want only to study the subject without sitting an exam are free to do so.

Working with Colin Elliott, an experienced professional horticulturist and garden designer, this CD-based course is your route to this highly respected and widely recognised qualification.
