Proceeds from the Spring Garden Fair go to fund horticulture educational programs for youth and adults,” said Union County Commissioner Chairman Sergio Granados.

As always, admission to the Spring Garden Fair is free, and parking is also free. Visitors are advised that all sales are cash only. All proceeds go to fund civic activities of the Master Gardeners, including raising and donating fresh produce and cut flowers to local food pantries and health care agencies, community beautification and education, support for the 4-H youth development program, and a Union County Sustainable Sciences student scholarship..

Among the hundreds of plants and seedlings offered for sale, the Spring Garden Fair features deer resistant, drought tolerant and fragrant plants that thrive in Union County, including many easy-to-grow plants for beginner gardeners. The Spring Garden Fair is also known for a large selection of herbs and tomatoes.

The 2023 Spring Garden Sale also features Rutgers soil test kits for sale and free gardening fact sheets composed by Rutgers faculty.

Master Gardener “Garden Helpline” volunteers will be available to answer gardening questions, and the Union County Bureau of Mosquito Control will have an educational display.
