The Grow Your Own Drugs ethnobotanist won Malaysia's first gold medal for a Chelsea show garden and said there are plenty more where that came from.
Wong said his heart lies in garden design rather than TV: "I'd love to do another show garden. I'm very excited that the Malaysia tourism minister has suggested they might do it again.
"We will of course if asked, there's no question. I hope they consider us. Malaysia has so much horticulture that's so different we could readily do a different garden every year."
He added: "I'm talking about lots of TV things. I want to do hard core ethnobotany - the science and nitty-gritty. Grow Your Own Drugs was fabulous but I'm interested in other areas of TV. I want to make science and horticulture cool for younger people."
