Seed Trials

Since 1982, Master Gardeners Volunteers have trialed selected annual vegetable and flower seeds in their home gardens across the state. Volunteers compare varieties and share their growing experiences, providing valuable information for home gardeners in Minnesota and the upper Midwest.
