Wigwams can be constructed out of bamboo canes in a triangular or square shape and fixed together at the top using twine. These are great for growing climbing beans or sweet peas.
Making your own using garden twigs or bamboo canes has a really natural look, perfect for a grow your own area. Ensure the branches or canes are a similar length, trimming down with secateurs if necessary. Then, push the canes into the soil at an equal distance from each other to create a circle shape. Gather the top of the canes together and the wigwam shape will form, and can be secured using garden twine.
For added support for the structure and for plants to climb up, feed twine round the structure, wrapping it around each branch for extra security.
