For many of us who grow food, late autumn brings cold weather and spells the end of the harvest. But the cold season doesn’t have to end your gardening journey. While it is true that some places, like USDA zones 0-2, have extremely short growing seasons that make growing vegetables outdoors extremely challenging, in most zones, even those where it snows every winter, you can continue to grow fresh herbs, vegetables, and even some flowers all year. Planting or placing your crops inside a greenhouse, coldframe, hot box, polytunnel, row cover, pop-up-plant protector, or heavy-duty gardening plastic will keep them growing through the fall and winter months. Some of these tools are inexpensive, while others can cost a small fortune. For example, a lean-to or freestanding greenhouse with walls made of polycarbonate plastic can be purchased or built for as little as a few hundred dollars, while a large walk-in greenhouse with walls of horticultural-grade glass can cost tens of thousands of dollars. These are some of the most common ways that you can extend your growing season from the early fall months, or even begin growing new crops in the winter.
