Edible Container Gardening. We are all familiar with containers of flowers for our decks and porches, but the Grey County Master Gardeners will focus on creating containers of edible flowers and vegetables. We will show you options for containers in the sun and the shade, with the best part being that everything in your planter is delicious! The Gardener in Residence program is presented by the Grey County Master Gardeners. Attend a monthly gardening demo followed by a 1-hour drop-in advice clinic for all your plant and garden queries.
