I walked through the heated greenhouse at Mass Hort, Elm Bank, in Wellesley MA. They’re getting ready for spring. Trays and trays of plugs are growing. Onions, broccoli, and lots of flowers.
They have two greenhouses. The small heated one and a large unheated one. Later they will transplant the plugs into larger pots, raise them to transplant size in the large greenhouse, then plant out to their garden.
They also have some full size tomato, watermelon, and marigold seedlings ready. I don’t know what they will do with those. They’ll need a larger heated or protected spot soon.
