Here's the structure I build every year for my beans. At each corner I drive in strong posts of wood to which I attach the canes and then build up the frame. I like this shape as you can easily access beans in and out. Also you get a gorgeous green shady tunnel. I am growing runner beans and climbing french beans up it - I put string acrosss the top so they can carry on climbing across the top and form a roof.
This picture of the potatoes was taken about a month ago and it's amazing how much they have grown since. They are also flowering.
I'm having one of those days. Do you get them? It feels like you've been turned inside out and any sad news you hear feels like it is drawing blood. I know you can find reasons for wars but when you break it down to what it is, it seems so incredible that we behave in this way. I honestly hope they'll be a day when it will un-understandable.
