Is Anything Happening in the Winter? Don’t yawn yet!

February 16, 2021

“Do ya need any help in the winter?” Visitors stop us from our work and ask this question, with some frequency. My response is, “Yes! But the winter tasks are not very sexy.”

How lucky are we. During these winter months, an energetic group of volunteers kept their shoulder to the plow. Here is what they have been working on, to stay warm:

moving plants, making new beds, working on drainage, root pruning, sheet mulching, building rabbit fencing, propagating plants, accounting catch-up, building and installing art, weeding and pruning out invasive plants, pruning perennial plants and trees, searching for winter moth eggs, rebuilding plant supports, ordering seeds and planning for spring gardens.

Volunteers needed! by appointment please email

Meanwhile, if you peel up that layer of snow, activity abounds and another group of volunteers are busy generating heat.

Tree roots grow in the winter, as long as there is moisture and the soil temperature is about 40°F or higher. On February 15, mid-afternoon, I took a soil thermometer and measured 40-42°F soil temperature in several locations at FECO. The air temp was 43°F and the snow temp was 35°F. The warm spot was within the chip pile at 50°F, a clear signal of active microbial life.

In fact, at 32° F, many microbes can thrive. Stoop down and imagine them snarfing up organic matter and ‘pooping’ out nitrogen and other nutrients that plants salivate for. Look closely and watch the plant root tips dribble out sugars, to bargain with the microbes for those nutrients.

All those biological and chemical processes require energy and produce heat; just the same as the volunteer work above ground. So, eat up first then come out to enjoy the outdoors. The volunteer schedule is on the Calendar page.

Many many thanks to our winter volunteers: Sue, Joe, Nancy, Miles, Nematode, Paige C, Rotifer, West, Reid, Worm, Lee, Amoeba, Jake, Bacteria, Becky, Jodi, Actinobacteria, Meg, AL, Gabbie, Pat, Karin, Kate, Fungi, and Melody
