Growing in a Changing Climate
Climate change is already impacting gardens, but how we garden can also impact climate change for good or for ill. We will look at projected changes to Maine’s climate and those gardening strategies we can employ to adapt to the new “normal.” We will also look at how to reduce greenhouse gas emissions from our gardens, from fertilizers to rototilling, and techniques to remove excess carbon dioxide from the atmosphere and store it in our soils and in living perennial biomass.

Discussion will include identification of tree species during the growing and dormant seasons, distinguishing features of evergreen species, and the ecological and economical functions of our forests.
Witness the seasonal evolution of the Burpee Kitchen Garden. Filled with edibles and floral accents, the garden’s wares range from arugula to zinnia, itty-bitty seedlings to 12-foot stalks.
