Learn to be a Professional Horticulturist

Based on the old RHS diploma in horticulture, this course has an emphasis on horticulture science, as well as practical aspects of plant establishment and selection. It is a superb all-round introduction to horticulture for anyone wishing to get a foothold in this rewarding industry.  


Course Structure

The Associate Diploma has two parts to it:

Stage 1: Eight Modules

Seven of these are available either online or by Distance Education. One of these eight (Practical Horticulture I) may only be taken online.

These eight modules form the Advanced Certificate in Horticulture. If you simply complete these eight modules and go no further you may attain an Advanced Certificate. Each module takes approximately 100 hours to complete, so the estimated duration for the eight modules is 800 hrs (minimum).

Stage 2: Seven Modules

All of these are available online, or by distance education. Once again, each module takes approximately 100 hours to complete, so the estimated total duration of the seven modules is 700 hours (minimum).
