Do you do diplomas? Norman, Sri Lanka

Dear Hugh I hope you can help. I wish my son to take one of your diplomas in garden design.
Forum (Hugh):Dear Norman, My company is not an institute for education. However I recommend you look under www.rhs.org.uk/education/docs/Diploma1.pdf This is The Royal Horticultural Society Colleges offering Courses Leading to: The RHS Diploma in Horticulture. These colleges also offer many other courses. Best regards Hugh O’Connell
