National Garden Bureau announces 2024 Green Thumb Award winners

National Garden Bureau, a 103-year-old non-profit organization that promotes gardening on behalf of the horticulture industry, is proud to announce the 2024 Green Thumb Award winners.

This year’s winners, for the first time, are in two categories: Professional’s Choice (voted upon by a panel of National Garden Bureau members) and the new People’s Choice (voted upon by 10,000 individuals from the gardening public).

Winners of the 2024 Green Thumb Awards were chosen based on these four criteria: uniqueness, technological innovation, ability to solve a gardening problem or provide a gardening opportunity, and appeal to gardeners.
