Ive had green thumbs, but it takes so much time and have ignored the tunnel totally for 2 seasons now. It was much more overgrown than i thought it would be but ive cleared a path through it and about 1/4 of it ready to use. But still too many nettles so have decided the simplest option is to cover the ground with plastic and lay lots of grow bags over it. It will mean lots of watering but its a start. I honestly believe we need to start looking at long term options now and having daily fresh food is a beginning.
