2025/26 RHS Interchange Fellow on placement from the USA to the UK

My first month at RHS Garden Wisley was spent working with the Trials Horticulture and Trials Curatorial teams. Having a background in trialling cultivated plants at the University of Georgia, it was interesting to compare how trials are planned, conducted, and evaluated within a charity like the RHS, as opposed to more industry-based settings, such as university trial gardens in the US. I felt at home in the trials garden as I prepped beds, took soil samples for future trials, and measured out plantings. Comparatively, on the office side of things, I learned about creating plans, sourcing plant material, and writing final reports for plant trials.

I found an especially interesting aspect of trialling is the forums in which AGMs are awarded. I observed the Gladiolus and Lantana forums and very much enjoyed seeing the discourse on what made (or did not make) a plant worthy of receiving an award of such importance, and I challenged myself to look beyond my own perspective and consider that of the home gardener whom the AGM is meant for. I also got to shadow judges at the Malvern Autumn Show in their evaluation of a wide range of plant displays. I learnt just how connected the world of horticulture is when some of the judges at Malvern were also some of the members on the trial forums! It was nice to already have some familiar faces in the short time that I had been in the UK.

Welcome and Riverside was the next team that I joined, and it was full of firsts. I learned how to coppice multi-stemmed trees and shrubs, built the framework for a dead-hedge, and scythed a meadow! As the seasons turn, tasks like collecting leaves become more regular, but it makes things like Curatorial Days that much more enjoyable. Curatorial Days are when all of the horticulturists on the Curatorial teams get together and work on big projects, the most recent being a mass planting of bulbs which will make for a beautiful display this upcoming spring. I feel that these days help further develop community within the gardens, and sometimes it just feels nice getting to break out of one’s daily routine.

In the midst of working with these incredible teams, I have attended a careers fair at a community college with the horticultural engagement manager, visited Fothergill’s seed packaging facilities and trials garden with the Trials Curatorial team, and took part in a plant collection workshop for members of Plant Heritage with the RHS Garden Wisley herbarium at RHS Garden Hyde Hall. It has been so much fun seeing all of the things the RHS does and meeting people within and outside of the organisation, and I cannot wait for what is to come in the rest of my time at RHS Garden Wisley and in the UK.
