As the autumn season arrives, temperatures drop, and frost becomes more likely to occur in your garden. How can you protect your vegetables from the cold? In November and December, gardening is limited due to lack of light and frost. We’ll show you how to build a greenhouse tunnel to keep these crops safe.
When to Build a Greenhouse Tunnel
Before building a greenhouse tunnel, consider alternative options for protecting your crops. If you only need to protect them for 3-4 weeks, you can use non-woven fabrics draped directly over the garden bed. In this case, the fabric should be stretched over the beds before frost arrives.
Materials Needed
To build a greenhouse tunnel, you’ll need:
- Archetts (lungs) – 2.4-2.5 meters long, 10.12 mm in diameter
- Galvanized wire
- Anchoring pins
- Fixing clips
- Canvas or polythene sheeting
Building Your Greenhouse Tunnel
Consult a local blacksmith to obtain the archetts, which will form the structure of your greenhouse tunnel. Position them 80-120 cm apart and bury the ends about 20 cm deep in the ground. To make the tunnel more stable, connect the archetts with galvanized wire, securing it with anchoring pins at both ends.
Next, stretch the canvas or polythene sheeting along the archetts. Secure it using fixing clips that attach to the archetts. To keep the structure in place, you can use wooden stakes and a cord, which should be tied around the tent and anchored to the ground with wire. Space the stakes about 30 cm apart to allow easy access.
Alternative Method: Fencing with Boards
If you don’t want to use galvanized wire, another option is to attach canvas or polythene sheeting to wooden boards placed on either side of the tunnel. While this won’t be as professional-looking as using wire and stakes, it’s still effective.
Tips for Building a Greenhouse Tunnel: Protect Your Crops from Frost
Before building a greenhouse tunnel, consider your garden’s specific needs and choose the right materials accordingly. The design should also take into account local building regulations and climate conditions.
When to Build a Greenhouse Tunnel
In areas with short winters, you can build a greenhouse tunnel in early autumn. However, if frost is a common occurrence, it may be more effective to start building your tunnel during the summer months when temperatures are warmer.
Materials Needed: A Comprehensive List
To ensure that you don’t forget anything crucial when building a greenhouse tunnel, make sure you have all the necessary materials at hand:
- Archetts (lungs) – 2.4-2.5 meters long, 10.12 mm in diameter
- Galvanized wire
- Anchoring pins
- Fixing clips
- Canvas or polythene sheeting
