Mother's Day Weekend Plant Sale and Seed Exchange The Humboldt Grange #501 will be hosting their Annual Mother's Day Weekend Plant Sale and seed exchange. The Plant Sale will be both Saturday May 13th and Sunday May 14th. Doors will be open between 9 a.m. and 4 p.m. both days. Located at 5845 Humboldt Hill Road, the Grange hall will be full of succulents, house plants, flowers, vegetables, and more. Also, there will be a large selection of seeds to share. The Grange is still in need of donations of plants and assistance with plant cleaning, pricing, and working the event. A couple of hours here or there would be most helpful. For more information or to volunteer call 707-442-4890, press 2 or 3 when prompted.
