Georgia’s biggest two-day plant sale returns this weekend as the Hall County Master Gardeners present the Fall Garden Expo on Friday, Sept. 20 and Saturday, Sept. 21, at Chicopee Woods Agricultural Center in Gainesville. Regular Expo visitors will recognize many returning vendors such as Nichols Nursery, Charles Street Garden, Smithgall Woodland Garden, Horizons Ltd and Gardeners Pottery. The public will have plenty of varieties of plants to choose from, including native plants which more gardeners agree are hardier and attract beneficial insects such as pollinators.
