DIY Year-Round Greens Harvesting: Build Your Own Cold Frame
Hey there, fellow gardening enthusiasts! Ever dream of fresh salads in the dead of winter? I know I have! That’s why I’m so excited to share this DIY project with you: building your own cold frame. It’s a fantastic way to extend your growing season and enjoy homegrown greens all year round. Trust me, there’s nothing quite like the taste of fresh spinach picked straight from your garden in January.
A cold frame is essentially a miniature greenhouse, a simple structure that protects your plants from harsh weather. It traps solar heat, keeping the inside warmer than the outside environment. This allows you to start seeds earlier in the spring, extend your harvest into the fall, and even overwinter some hardy plants.
Why Build a Cold Frame?
Before we dive into the how-to, let’s quickly recap why a cold frame is such a game-changer:
* Extended Growing Season: Grow greens and other cool-season crops well beyond their typical season.
* Early Seed Starting: Get a head start on your spring garden by starting seeds indoors and then hardening them off in the cold frame.
* Winter Harvesting: Enjoy fresh salads and other greens even when the ground is frozen solid.
* Plant Protection: Shield your plants from frost, snow, wind, and pests.
* Cost-Effective: Building your own cold frame is much cheaper than buying a greenhouse.
Materials You’ll Need
Okay, let’s gather our supplies. This project is relatively simple, and you can often repurpose materials you already have on hand. Here’s what I used:
* Lumber:
* (2) 2×12 boards, 8 feet long (for the back and front)
* (2) 2×12 boards, 4 feet long (for the sides)
* (1) 2×4 board, 8 feet long (for the lid frame)
* Clear Covering:
* Old window or storm door (This is what I used, repurposing is great!) or
* Polycarbonate sheets (durable and lightweight) or
* Heavy-duty plastic sheeting (least expensive, but less durable)
* Hardware:
* Wood screws (various sizes)
* Hinges (2-3, depending on the size of your lid)
* Handle or knob (for the lid)
* Eye hooks and chain (optional, for propping the lid open)
* Tools:
* Saw (circular saw or hand saw)
* Drill
* Screwdriver
* Measuring tape
* Pencil
* Safety glasses
* Gloves
* Level
Building the Cold Frame Box
This is the foundation of our project. We’re essentially building a rectangular box with a slanted top.
1. Cut the Lumber: Using your saw, cut the lumber according to the following dimensions:
* Back: 2×12 board, 8 feet long
* Front: 2×12 board, 8 feet long
* Sides: 2×12 board, 4 feet long
2. Assemble the Box: Now, let’s put the pieces together.
* Place the back board on its edge.
* Attach one of the side boards to the back board, forming a 90-degree angle. Use wood screws to secure the connection. Make sure the screws are long enough to penetrate both boards securely.
* Repeat with the other side board.
* Attach the front board to the side boards, completing the rectangular box.
* Important: Ensure the box is square by measuring the diagonals. They should be equal. If not, adjust the box until it’s square.
3. Reinforce the Corners: For added stability, you can reinforce the corners with additional pieces of wood or metal brackets. This is especially important if you’re using heavier materials for the lid.
4. Level the Box: Place the box in its desired location in your garden. Use a level to ensure it’s sitting evenly. If necessary, add soil or shims under the corners to level it. A level base will help with drainage and prevent water from pooling inside the cold frame.
Creating the Cold Frame Lid
The lid is crucial for trapping heat and protecting your plants. We’ll build a simple frame and attach our clear covering.
1. Measure the Box: Carefully measure the outside dimensions of the box you just built. This will determine the size of the lid frame.
2. Cut the Lid Frame Lumber: Using your 2×4 board, cut the lumber to create a rectangular frame that is slightly larger than the box opening. This overhang will help prevent rain and snow from entering the cold frame. I usually add about an inch on each side.
* Cut two pieces to the length of the box plus 2 inches.
* Cut two pieces to the width of the box plus 2 inches.
3. Assemble the Lid Frame: Assemble the rectangular frame using wood screws. Ensure the frame is square and sturdy.
4. Attach the Clear Covering: This is where your choice of material comes into play.
* Using an Old Window or Storm Door: If you’re using an old window or storm door, simply attach it to the lid frame using hinges. Make sure the hinges are strong enough to support the weight of the window.
* Using Polycarbonate Sheets or Plastic Sheeting:
* Cut the polycarbonate or plastic sheeting to the size of the lid frame, allowing for a few extra inches on each side.
* Center the sheeting on the frame.
* Secure the sheeting to the frame using staples, tacks, or screws with washers. Make sure the sheeting is taut and wrinkle-free.
* Trim any excess sheeting with a utility knife.
5. Attach the Lid to the Box: Position the lid on top of the box and attach it using hinges. Make sure the hinges are aligned properly so the lid opens and closes smoothly.
6. Add a Handle or Knob: Attach a handle or knob to the lid for easy opening and closing.
7. Optional: Add Eye Hooks and Chain: To prop the lid open at different angles for ventilation, you can install eye hooks on the inside of the box and attach a chain to the lid. This allows you to adjust the amount of ventilation based on the weather conditions.
Preparing the Cold Frame for Planting
Now that our cold frame is built, let’s get it ready for planting!
1. Prepare the Soil: The soil inside the cold frame should be well-draining and rich in organic matter. You can either amend the existing soil or add a layer of fresh potting mix. I like to use a mix of compost, peat moss, and perlite.
2. Plant Your Greens: Choose cool-season greens that are suitable for growing in a cold frame. Some good options include:
* Spinach
* Lettuce
* Kale
* Arugula
* Mustard greens
* Radishes
* Swiss chard
3. Water Thoroughly: After planting, water the greens thoroughly.
4. Mulch: Add a layer of mulch around the plants to help retain moisture and suppress weeds. Straw, shredded leaves, or wood chips are all good options.
Maintaining Your Cold Frame
Maintaining your cold frame is essential for ensuring healthy plant growth.
1. Ventilation: Ventilation is crucial to prevent overheating and excessive humidity. On sunny days, open the lid of the cold frame to allow for airflow. The amount of ventilation will depend on the temperature and the type of plants you’re growing.
2. Watering: Water your plants regularly, but avoid overwatering. The soil should be moist but not soggy.
3. Weeding: Remove any weeds that appear in the cold frame.
4. Pest Control: Monitor your plants for pests and diseases. If you find any, take appropriate action to control them.
5. Temperature Monitoring: Keep an eye on the temperature inside the cold frame. A thermometer can help you track the temperature and adjust ventilation as needed.
Tips and Tricks for Success
Here are a few extra tips to help you get the most out of your cold frame:
* Location, Location, Location: Choose a sunny location for your cold frame. South-facing locations are ideal.
* Insulation: To further insulate your cold frame, you can add insulation to the outside walls. Straw bales, blankets, or bubble wrap can all be used for insulation.
* Thermal Mass: Adding thermal mass to the cold frame can help regulate the temperature. Rocks, bricks, or water-filled containers can absorb heat during the
