Lumpkin County Parks & Recreation, 365 Riley Road, Dahlonega. You probably know about dirt, but this month we’ll learn the nitty-gritty on soil. Our May speaker is Arborist Odis Sisk from Green Prism Consulting who will help us understand the low down on our north Georgia soil and how to test and improve it to make landscapes thrive. The presentation is sponsored by Georgia Mountains Master Gardeners and is free and open to the public. For information contact Lumpkin County Extension at uge1187@uga.edu  or 706-864-2275.
