Create a mini greenhouse to put outside for cold stratification of native seeds. No fuss and lots of seedlings come June! We are collecting translucent jugs in the COA entrance so we can put holes in the bottom to prepare for creating the greenhouses. Bring your translucent jug to the COA and drop it in the collection bin in the entrance. Or bring it with you! Please call the COA at 978-318-3010 to reserve your place.
