Step 1: Fixing trellis against a wall

Fit 40 mm (1.75in) battens on a wall, attached securely to the brickwork with brass screws placed every 6cm (2in).
To do this, drill holes into the brickwork, at least 35mm (1.5in) deep. Insert a rawlplug or similar before attaching the battens. Battens should be spaced about 1m (3ft) apart along the length of the trellis.
Nail the trellis onto the battens using galvanised nails.
Tip: Ensure you do not fix battens below the damp proof course, or that the trellis extends beyond it.

Step 2: Fixing trellis out from a wall

You can erect a trellis archway by fixing it at right angles to a wall.
Start by fixing a vertical batten along the length of the trellis that will touch the wall (see Step 1).
Screw fence clips onto the batten at about 30cm (12in) intervals.
Attach trellis to clip by screwing through the side of the clip with brass screws.

Step 3: Fixing trellis on fences and free-standing trellis

Trelliswork not attached to a wall needs sturdy supports, such as wooden posts measuring at least 50 mm sq (2in sq).
Dig foundation holes at least 450 - 600 mm (1.5in - 2.5in) deep and fix supporting posts with hardcore and cement, ensuring the posts are fixed vertically and in line with the direction of the trellis. Attach trellis to the posts with fence clips as described above.
Trellis work can be used to extend a fence to give added privacy. Use metal fence post collars that fit over the top of existing posts and add a further extension post. Screw securely to the collar with brass screws. Then fix trellis work to the extension posts using fence clips.
Tip: Nail on a post cap to prevent the top from rotting.
Alternatively, you can fix trellis work up and above the side of a fence. Insert sturdy cup hooks into fence posts and hook the trellis work on so that the trellis is easily removed for fence maintenance.
Tip: It's best to only grow annual climbers such as sweet peas against this kind of trelliswork to allow easy access to the fence.
