deadheading waterlilies at WisleyWork-based training at RHS Gardens

For more than 100 years, the RHS School of Horticulture training courses have been a way of providing students with the means of converting theoretical studies from the classroom into practice in a real garden setting. Students can then become horticulturists who get their hands dirty, have excellent knowledge and are hugely respected within the horticultural industry.
