Willow arch for beans

Yesterday A's 9yr old and I went down to the community gardens to cut down some noxious Pussy Willow from near the stream there. This is a type of willow which has destructive tendencies along the streams and swamps of The Blue Mountains. However! The long bendy sucklings of the willow make for perfect arch building. I've been planning an arch for my scarlet runner beans to grow up and over, and decided to build one, rather than spend more $. After watching some quick tutorials from the web on square lashing knots I have now built the main structure. :) It's pretty solid - I used garden stakes bashed into the ground as the foundation and then tied to each a willow suckling on each side. Bent them down in the middle and tied that together. I used mainly wire in variations of the square lashing knot because - well...wire is wire. I will soon tie more cross sticks to create a better grid for the beans to climb up. One thing that A has advised however is to watch out for the sucklings taking root! Apparently they just need a bit of water, put them in the ground and watch out! So I will probably take down the arch at the end of the season to avoid this....
