Mycoterra Farm by Julia Coffey is in the woodlands of Westhampton MA. With a passion for growing things and wanting to grow a business of her own, she decided a mushroom farm would be an excellent complement to the Pioneer Valley’s robust local agricultural economy.  Well received in the Pioneer Valley and beyond, Mycoterra Farm has grown to a new location in South Deerfield MA.

Buying Mycoterra mushrooms keeps your dollar local and supports local farming and sustainability. Mycoterra mushrooms are handcrafted in small batches and picked fresh for delivery. We take pride in producing diverse varieties of quality gourmet mushrooms. Our Mushrooms are available at farmers markets across the state, various farm stands, River Valley Market, and the farm store at our new location.

We grow more than just mushrooms.  We strive to leave the planet better than we found it. Using agricultural and forestry byproducts as our primary growing mediums, our natural methods of production accelerate decomposition, building soil and cycling nutrients – critical processes for healthy ecosystems.  We use our exhausted substrates as soil amendments on our farm to help restore an old gravel bank, prevent erosion and to build organic matter in our annual and perennial garden beds.

Peach update

There are no peaches for harvest in Massachusetts this year — an unfortunate casualty of increasingly variable weather fueled by climate change. We are keeping the guide updated with information about other fruit that is available, along with farms that are sourcing peaches from other parts of the region.
