Hi I'm new to this site and forum I just signed up today and noticed some of this thread is 7 years old! That's amazing I love this site.
We haven't built a bean trellis before but I decided to use an idea i had seen using some left over giant Russian sunflower stalks to build a teepee. I have tried to compost them before they take some time so I thought why not use them first then compost later.
So if we grow a crop of giant Russian's, we can make new replacement teepees Every year and always have new material coming in..
