Growing Spinach All Year Round: My DIY Cold Frame Hack
Hey there, fellow garden enthusiasts! I’m so excited to share my secret weapon for enjoying fresh, delicious spinach all year round: a DIY cold frame! Forget those sad, wilted bags from the grocery store – with this simple project, you can have vibrant, homegrown spinach even when the snow is falling. I’ve been using this method for a few years now, and trust me, it’s a game-changer.
Why a Cold Frame for Spinach?
Spinach is a cool-weather crop, thriving in temperatures between 50°F and 65°F. While it can tolerate some frost, harsh winters can definitely put a stop to your spinach party. A cold frame acts like a mini-greenhouse, trapping solar heat and protecting your plants from freezing temperatures, strong winds, and heavy snow. This allows you to extend your growing season significantly, harvesting spinach well into the winter and starting your spring crop much earlier.
Materials You’ll Need
Before we dive in, let’s gather our supplies. The beauty of this project is that you can often repurpose materials you already have lying around!
* **Lumber:** You’ll need lumber for the frame itself. I used reclaimed 2x4s for the sides and 2x6s for the back (to create a slight slope). The amount you need will depend on the size of your cold frame. I recommend a frame that’s at least 3 feet wide and 4 feet long to give your spinach plenty of room to grow.
* **Clear Covering:** This is crucial for letting sunlight in. I’ve had great success with old storm windows, but you can also use heavy-duty plastic sheeting, polycarbonate panels, or even an old glass shower door. Just make sure it’s transparent and durable.
* **Hinges:** You’ll need hinges to attach the lid to the frame, allowing you to easily access your spinach.
* **Screws or Nails:** For assembling the frame.
* **Drill or Hammer:** Depending on whether you’re using screws or nails.
* **Saw:** To cut the lumber to the desired lengths.
* **Measuring Tape:** For accurate measurements.
* **Safety Glasses:** Always protect your eyes!
* **Gloves:** To protect your hands.
* **Optional: Weather Stripping:** To seal any gaps and improve insulation.
* **Optional: Handles or Knobs:** To make opening and closing the lid easier.
* **Spinach Seeds or Seedlings:** Of course! Choose a variety that’s known for its cold hardiness, like ‘Winter Bloomsdale’ or ‘Giant Winter’.
* **Good Quality Soil:** Spinach needs well-drained, fertile soil. I recommend a mix of compost, topsoil, and a little bit of sand or perlite.
Building Your Cold Frame: Step-by-Step Instructions
Okay, let’s get building! This project is relatively simple, even for beginner DIYers.
1. Planning and Measuring
* Decide on the Size: Before you start cutting wood, determine the dimensions of your cold frame. Consider the space you have available in your garden and the amount of spinach you want to grow. As I mentioned, a minimum of 3×4 feet is a good starting point.
* Measure and Cut the Lumber: Based on your chosen dimensions, measure and cut the lumber to the appropriate lengths. Remember to account for the slope of the lid – the back of the frame should be taller than the front. I usually aim for a difference of about 6-8 inches.
* Example Measurements (for a 3×4 foot frame with a 6-inch slope):
* Front: Two pieces of 2×4 lumber, each 3 feet long.
* Sides: Two pieces of 2×4 lumber, each 4 feet long.
* Back: One piece of 2×6 lumber, 3 feet long.
2. Assembling the Frame
* Build the Box: Using screws or nails, assemble the lumber to create a rectangular box. Make sure the corners are square and the frame is sturdy. I like to use wood glue in addition to screws for extra strength.
* Reinforce the Corners: For added stability, you can add corner braces or metal brackets to the inside corners of the frame. This will help prevent the frame from warping or falling apart over time.
3. Preparing the Lid
* Measure the Opening: Carefully measure the inside dimensions of the frame opening. This will determine the size of your lid.
* Cut the Covering Material: Cut your chosen covering material (storm window, plastic sheeting, etc.) to the appropriate size. Make sure it’s slightly larger than the opening so it overlaps the frame.
* Attach the Covering (if necessary): If you’re using plastic sheeting, you’ll need to attach it to a wooden frame. You can build a simple frame using 1×2 lumber and staple the plastic sheeting to it.
4. Attaching the Lid
* Position the Hinges: Place the hinges along the back edge of the frame and the lid. Make sure they’re evenly spaced and aligned properly.
* Attach the Hinges: Using screws, attach the hinges to both the frame and the lid. Test the lid to make sure it opens and closes smoothly.
5. Adding Finishing Touches
* Install Weather Stripping (Optional): If you want to improve the insulation of your cold frame, you can install weather stripping around the edges of the lid. This will help seal any gaps and prevent heat from escaping.
* Attach Handles or Knobs (Optional): Adding handles or knobs to the lid will make it easier to open and close, especially when it’s cold or wet outside.
* Sand and Paint (Optional): If you’re using reclaimed lumber, you may want to sand it down and paint it to give your cold frame a more polished look. This will also help protect the wood from the elements.
Planting Your Spinach
Now for the fun part!
1. Preparing the Soil
* Choose a Sunny Location: Select a spot in your garden that receives at least 6 hours of sunlight per day.
* Amend the Soil: Dig a hole inside the cold frame and amend the soil with compost and other organic matter. Spinach prefers well-drained, fertile soil with a pH between 6.0 and 7.0.
* Level the Soil: Rake the soil to create a smooth, even surface.
2. Sowing the Seeds or Transplanting Seedlings
* Sowing Seeds: Sow spinach seeds directly into the soil, spacing them about 1 inch apart and covering them with about 1/2 inch of soil. Water gently.
* Transplanting Seedlings: If you’re using seedlings, dig small holes in the soil, spacing them about 4-6 inches apart. Gently remove the seedlings from their containers and plant them in the holes. Water thoroughly.
3. Watering and Maintenance
* Water Regularly: Keep the soil consistently moist, but not waterlogged. Water deeply whenever the top inch of soil feels dry.
* Ventilate the Cold Frame: On sunny days, open the lid of the cold frame to prevent overheating. Spinach prefers temperatures between 50°F and 65°F.
* Weed Regularly: Remove any weeds that pop up in the cold frame. Weeds can compete with your spinach for nutrients and water.
* Fertilize (Optional): If your spinach plants are looking pale or stunted, you can fertilize them with a balanced organic fertilizer.
Overwintering Your Spinach
This is where the magic happens!
1. Monitoring Temperatures
* Keep an Eye on the Thermometer: Use a thermometer to monitor the temperature inside the cold frame. On very cold nights, you may need to add extra insulation, such as blankets or straw bales, to protect your spinach from freezing.
* Ventilate on Sunny Days: Even in winter, the cold frame can get quite warm on sunny days. Be sure to open the lid to ventilate and prevent overheating.
2. Watering and Snow Removal
* Water Sparingly: In winter, spinach needs very little water. Water only when the soil is dry to the touch.
* Remove Snow: If heavy snow accumulates on the lid of the cold frame, remove it to allow sunlight to reach your spinach plants.
3. Harvesting
* Harvest Regularly: You can start harvesting spinach leaves as soon as they’re large enough to eat. Simply snip off the outer leaves, leaving the inner leaves to continue growing. This will encourage continuous production.
* Enjoy Your Fresh Spinach! Use your homegrown spinach in salads, soups, smoothies, or any other dish you like.
