- Supports – you can use metal stakes with poly piping forming an arch over the top, or approx. 3m-long bamboo poles, flexible enough to be bent over in an arch.
- Cross bracing – bean poles or extra bamboo
- Twine
- Frost-protection fabric – an old sheet or shade cloth will do, or you can buy material specifically made for this purpose.
- Staple gun or other means of fixing the cloth
- Create the basic tunnel by placing arched supports every 50cm or so along the line of plants you want to protect.
- Cross-brace the tunnel by using twine to tie poles between the arches; this will stabilise the structure.
- Cover the tunnel with fabric of your choice and fix in place with staple gun or safety pins.
- Cut and attach end panels to the tunnel, or allow some extra fabric that can be tied together to cover the ends.
