Garden Series: Greenhouse Gardening in the Winter, P3

Cool season crop, Yukon Spinach, was direct-seeded in my Calgary, Alberta greenhouse on September 19 and harvested starting in late October. My high-low thermometer shows coldest temperatures inside the greenhouse as low as minus 6 degrees C so far this fall. I supply some frost protection by using a small electric heater set to a “frost protection” setting but I don’s have grow-lights inside my greenhouse and so I will only get one or two harvests of spinach this winter. I harvest leaves individually instead of pulling the whole plant out and I expect another harvest from these same plants in December.  In Alberta and other northern climates, fall-seeded outdoor spinach will start growing again outside from late March to early April while  greenhouse spinach will grow actively again by the end of February. In other words, the greenhouse offers an opportunity for cool winter crop harvests and a big boost in harvest length compared to outdoor crops.
