Cold Frames: Extend your Growing Season

Cold frames are an easy and affordable way to extend the growing season. The enclosed structure sits on top of the ground and is usually 12-18 inches deep. The base is filled with a nutrient rich planting mix and topped with a clear lid to allow for natural light. These mini greenhouses use solar energy and insulation to create a microclimate, with no need for artificial heat.


It’s simple to start. Pick the warmest spot in your yard that’s also easy to access. Remember – Mother Nature may make it more difficult to get to your cold frame as the winter season progresses! Great drainage should be a consideration, as it will make for better growing. Then it’s time to choose your vegetables. Arugula, broccoli, beets, cabbage, chard, green onion, kale, lettuce, radish and spinach will all thrive in this environment. Cold frames can also be used to over winter some tender perennials, especially herbs.

Cold frames and greenhouse growing offer solutions to growing veggies all year round. Come in to Back to Nature today and find out how to get started. We have a number of small, medium, and custom cold frames along with great options for greenhouse growing.
