Taught by Tom Cole

‘The love of gardening is a seed once sown that never dies‘ ~ Gertrude Jekyll

Course Description

This module will enable candidates to make informed decisions about how best to tackle common risks to plant health, such as pests, and viral and bacterial diseases. Candidates will cover the symptoms of prevalent diseases, and consider the best way to treat these problems without harming the environment or upsetting the natural balances in their garden. Additionally, this module will look at weeds - the reasons for their success, and the best ways to minimise their impact.
