Building a wall trellis for climbing plants that is attractive and able to support a bounty of heavy fruit or flowers throughout the season requires less than an afternoon of time and very little expense. It weighs less than 2 kg and, after the initial installation, it can be erected or disassembled in 30 minutes. It can be stored in an area only 1.2 metres long and 30 cm diameter. Sweet peas and jasmine, as well as raspberries and other climbing flowering plants, work extremely well on this simple trellis.
Use an electronic stud-finder tool to locate the wood stud on the inside of the wall where the trellis will be placed.
Measure 1.5 metres up the wall from the ground and place a pencil mark on the outside of the wall in the middle of the stud. Use a carpenter's level to measure a spot 1.3 metres straight down in line with the first mark and place a second mark.
Use a carpenter's level to measure a spot that is 1.3 metres across the wall to the middle of the next stud on the wall. Measure 1.5 metres up the wall from the ground and place a pencil mark in the middle of the stud. Use a carpenter's level to measure to a spot 1.3 metres straight down in line with the top mark and place a second mark.
Repeat the same process 1.3 metres across the wall to the middle of the next stud.
Use an electric drill to bore a 2 cm hole through the wall and into the stud in each of the six marks. Screw a heavy-duty 2 cm thick and 20 cm long stainless steel eye-hook into each of the holes.
Place an 2.5 metre long and 1.3 metre wide section of heavy-gauge wire grid fencing, available from builder's merchants or DIY shops and generally used as fencing for livestock, over each of the six eye-hooks. The top of the fence fits over the top eye-hooks and the bottom of the fence fits over the bottom eye-hooks.
Use a pair of channel-lock pliers to squeeze the six eye-hooks together, closing each hook over the wire. The wire fence is now supported off the ground and out away from the wall.
Plant flowering plants or bushes at the base of the trellis so that the vines have easy access to climb up the fencing.
The trellis can be left up year round or the eye-hooks can be prised open using two sets of channel-lock pliers, one to hold the base of the eye-hook and the other to pull up the hook itself.
