GrassRoots Growers will be hosting an evening devoted to trees with speaker Tim Gray. Tim, who is a graduate of Sir Sandford Fleming College, worked for 30 years with the Ontario Ministry of Natural Resources, subsequently with Trees Ontario, and currently with Forests Ontario. Also on that night GrassRoots Growers will hold its fall seed exchange. Now is the time to collect seeds and bring your extras to the meeting. Please label them clearly and package them securely. The seed exchange is free, and if you are a starting gardener, don’t worry about not bringing seeds to trade. Event takes place at 7 p.m. at St. Patrick School in Erinsville, 6041 County Road 41, Erinsville.
