Transplanting, Re-potting, & Dividing Demonstration with the Gardener in Residence. The Grey County Master Gardeners will be discussing and demonstrating how to transplant seedlings and other potted plants, including how to repot your existing plants (indoor and outdoor). As perennials need dividing, we'll show you various techniques to use when you need to divide your perennials. Bring your questions! 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.
