What is a Cold Frame?
A cold frame is a simple and practical structure designed to protect plants from harsh weather conditions, particularly from extreme cold temperatures. It is often constructed using a wooden or metal frame, with a transparent covering material, such as glass or clear plastic, placed on top.
This covering allows sunlight to penetrate while trapping heat, creating a warm and favorable microclimate for plants.
Purpose of Using Cold Frames
The primary purpose of using a cold frame is to provide a controlled environment that extends the growing season. By creating a microclimate in the cold frame, you can cultivate plants earlier in the spring and continue growing them well into the fall or even winter, depending on your climate.
If built correctly, it can stop the ground from freezing in the fall, and let it warm up quicker in the spring.
Benefits of Using a Cold Frame
Using a cold frame offers several benefits to gardeners:
- Protection from Cold Weather: Cold frames shield plants from frost, chilling winds, and fluctuating temperatures that can otherwise damage or kill delicate plants. To learn more, check out our post about how to protect your plants from freezing conditions.
- Improved Growth Conditions: The warm and sheltered environment within a cold frame encourages better growth and development of plants, allowing you to grow a wider variety out of season.
- Cost-effective: Constructing a cold frame is relatively inexpensive compared to building a greenhouse, making it an affordable option for small-scale gardeners.
Best Plants for Cold Frames
Cold frames are suitable for a range of plants, especially those that can tolerate cooler temperatures. To purchase any of the following vegetable seeds, simply click its name! Some of the most suitable plants for a cold frame include:
- Leafy Greens: Varieties such as spinach, kale, lettuce, and chard thrive in the protected environment of a cold frame.
- Root Vegetables: Carrots, beets, radishes, and turnips can be successfully grown in a cold frame, as they withstand cold temperatures well.
- Herbs: Cold frames are excellent for cultivating herbs like cilantro, parsley, chives, and dill.
In short, choose vegetables that are somewhat tolerant of cold weather so that they will easily survive the conditions of the season.

Creating your own cold frame is a straightforward process. Here’s a step-by-step guide to help you get started:
- Select a suitable location: Choose a spot that receives ample sunlight throughout the day, preferably facing southward to maximize exposure.
- Choose the frame material: Decide whether you want to use wood, metal, or a combination of both for the frame structure. Ensure it is sturdy enough to withstand the elements.
- Construct the frame: Assemble the frame according to your desired dimensions, ensuring it has a sloping angle to allow rainwater and snow to slide off easily.
- Attach the covering material: Lay your chosen transparent material, such as glass or plastic, over the frame and secure it tightly to prevent strong winds from dislodging it.
- Provide ventilation: To avoid overheating, create a vent by leaving a small gap or installing a hinged window at the top of the frame that can be opened or closed as needed.
- Prepare the soil: Clear the ground within the frame and amend the soil with organic matter, such as compost, to provide optimal nutrition for your plants. When organic matter, like compost or mulch, breaks down, it generates heat that will further heat up the cold frame.
- Plant and customize: Select your desired cold-tolerant plants and arrange them within the cold frame, leaving room for growth.
- Monitor and maintain: Regularly monitor the temperature inside the cold frame, ensuring it doesn’t get too hot or cold. Water and provide additional insulation during colder periods, if required.
By following these steps, you can create your very own cold frame and enjoy an extended growing season for your favorite plants.
