Join Escher Cattle for a discussion of a condensed history of container plants and their benefits,overview of ther needs and care in indoor and outdoor spaces, and some common pitfalls,pests and diseases they face.

Growing Figs on Cape Cod

Master Gardener Rich Trimble will take participants through a year in the life of a Cape Cod fig tree. He will share tips for successfully growing subtropical figs here in zone 7 as well as information about the different varieties of fig trees, and the unique relationship with the fig wasp in their native environment. Rich will bring a fig tree or two and have a Q&A period following his presentation.

Growing Mushrooms

Chase Freeman is a software engineer turned mushroom farmer. Together, he and his wife Brianna operate the Cape Cod Mushroom Company. A North Texas native, Chase migrated north after Briannna (born and raised in Sandwich) convinced him to trade the plains for the shoreline, where he has grown to love the landscape of the Cape. Chase found his way into mushroom farming through Unicorn Bags, the industry standard for growing gourmet varieties, where he helped build the manufacturing pipelines behind their operational visibility. He now applies that same engineering mindset to Sporeline, a platform he is building to track the full lifecycle of mushrooms from spore to harvest.
