Watts started at Architectural Plants during his school holidays and was tutored by White.
He left Architectural Plants to embark upon a record-breaking row of 3,160 nautical miles from Australia to Mauritius. He and his rowing partner became the first and fastest paired team to row unassisted from land to land across the Indian Ocean in 102 days, 13 hours and 40 minutes.
Watts co-founded the charity, Streetscape, a social enterprise that provides apprenticeships in landscape gardening to 18-25 year olds who are long-term unemployed.
Since returning to Architectural Plants in October 2015, Watts has doubled production of home-propagated plants and has given work experience placements and jobs to new graduates and students from local colleges.
