The London College of Garden Design has appointed Jo Thompson as its new head of garden design studies, taking up the position in September 2026. She will oversee the college’s flagship Garden Design Diploma, a program that has launched countless careers since its launch two decades ago.
Thompson’s arrival follows the college’s decision to bolster its teaching faculty with active practitioners. She will work alongside Duncan Cargill, a graduate of the diploma and co-founder of Cargill Sykes, who has been named deputy head. Both will maintain their private design practices while leading curriculum updates, student mentorship, and industry partnerships.
Among Thompson’s recent work is the 75th Anniversary Garden for The Archers at the RHS Badminton Flower Show in July 2026, as well as her 2025 showcase at the RHS Chelsea Flower Show. Her designs, known for their romantic, color-focused approach, have earned praise for making sophisticated techniques accessible to students through her teaching.
“I know just how important good guidance and mentorship is, and together with Duncan, I’m looking forward to being able to work with the next generation of garden designers, helping them to understand how to create gardens by going beyond the textbooks and digging deeper into what makes a truly successful outdoor space.”
This appointment aligns with the college’s broader effort to integrate industry leaders into its teaching staff, ensuring alignment between education and professional demands. Nina Baxter, the college’s director, described Thompson and Cargill as “outstanding designers with a deep commitment to education and professional development.” She highlighted their ability to connect academic instruction with real-world practice.
Cargill, who will concentrate on developing student confidence and technical proficiency, stressed the diploma’s standing for professional readiness. “The Garden Design Diploma has earned a reputation for excellence and professionalism, and it is a privilege to join the leadership team at such an exciting time. I am passionate about helping students bridge the gap between education and practice, giving them the confidence, skills and knowledge needed to build successful careers.”
The two will assume their roles in September 2026, marking a new direction for the college as it adapts its programs to meet industry changes.
