Tired of your plants suffering through unpredictable weather or a short growing season? With a DIY folding greenhouse, you can protect your garden, boost your yields, and grow fresh veggies, herbs, and flowers year-round—right in your backyard!
This easy-to-make, space-saving structure is perfect for beginners and seasoned gardeners alike. Let’s break it down step by step!
1. Gather Your Materials & Tools
You’ll need:
- 1” PVC pipes + connectors
- Clear plastic sheeting (greenhouse-grade)
- Wooden planks (for the base)
- Heavy-duty hinges
- Zipper or Velcro strips (for the door flap)
- Screws, clamps, or staples
- Tools: Saw, drill, screwdriver, tape measure, heat gun (optional)
2. Design Your Greenhouse
Measure your garden bed and decide on your structure’s shape:
- A-frame for a classic, angular look
- Hoop-style for easier bending and more growing height
Sketch out your design and plan for:
- A hinged fold-down frame
- Access points (zippered or Velcro flap)
- Vents for airflow
3. Build the Wooden Base
Create a sturdy rectangle to sit over or around your garden bed:
- Use treated lumber to resist rot
- Drill pilot holes before adding screws to prevent splitting
- Double-check that the base sits level on the ground
4. Build and Attach the PVC Frame
- Cut PVC pipes to your desired length
- Connect using elbow and T-joint fittings
- Add cross braces for strength
- Use screws or brackets to secure the frame to the wood base
Optional: For a hoop house, bend the pipes over your bed and anchor them into the ground or frame.
5. Add Hinges for Folding
- Attach heavy-duty hinges where the frame meets the base
- This allows you to fold the greenhouse back for easy access, ventilation, or storage
- Make sure the hinges are aligned so folding is smooth and stable
6. Cover with Plastic Sheeting
- Cut the plastic to size and drape it over your frame
- Use staples, clamps, or screw-in battens to secure the cover
- Smooth out wrinkles and use a heat gun (carefully!) to tighten it up if needed
7. Add Doors & Vents
- Create an entry flap using a zipper or Velcro
- Cut small holes near the top and cover with mesh for ventilation
- This lets hot air escape and helps prevent mold or pest issues
8. Anchor It Down
Secure your greenhouse to the ground using:
- Stakes at the corners
- Sandbags or bricks if building on a patio or hard surface
- Test the folding feature to make sure it opens and closes easily
