Plant supports like trellis and wigwams serve a practical purpose, but can also be focal points in their own right.

A simple, metal obelisk can easily be created using galvanised garden wire and metal rods. Create an interesting shape by bending the rods and securing them in place with the wire. The structure can be as big as you like, although a minimum of about 1m high is best for the most lightweight climbers. If you plan to extend the height beyond this, then increase the depth of the supporting timber base. Other plant supports you could try your hand at include a rustic hazel trellis, willow supports and bamboo supports.

Create your own metal obelisk in next to no time, with the help of our step-by-step guide.

Trellis and wigwams serve a practical purpose, but can also be focal points in their own right.

You will need

  • Piece of timber measuring 15cm high x 15cm wide x 5cm deep for the base
  • Six 1 metre-long, 8mm diameter zinc thread rods
  • 30m of 1.5mm galvanised garden wire
  • 5m of 1mm galvanised garden wire
  • Pliers to cut the wire
  • Drill and 8mm drill bit

You Will Need

  • Piece of timber (15cm high x 15cm wide x 5cm deep), for the base
  • Zinc thread rods (six 1m long, 8mm diameter)
  • Galvanised wire (1mm, 5m length)
  • Galvanised wire (1.5mm, 30m length)
  • Pliers
  • Drill
  • Drill bits (8mm)

Total time:

Step 1

Draw a circle of 14cm diameter onto the timber square. Drill six 8mm wide holes at equal distances around the circle. Gently bend the rods to create a curving effect and tweak until they’re all the same (try bending over the edge of an old table for more control).


Step 2

Push the rods into the holes in the timber and position them so they curve outwards.


Step 3

To secure the tops, weave a ring of garden wire around them, approximately 2cm thick, to the same diameter as the top of the obelisk.


Step 4

Push the wire ring over the ends of the rods to make a rim and bind it in place with 1mm wire. Add rings at regular intervals down the structure and attach with more wire.


For even greater impact, use this obelisk as a garden sculpture, without planting any climber up it, to keep its lines clear and visible.
