I planted as many patches of mud as I could find (particularly any of those in front of hard river walls). I also planted lots around an illegal sewage outfall, where the first trees I planted to naturalise it last year were already coming on well. The final planting of the day was to try to bring to life a slightly quixotic idea of mine to build a chapel out of willow beside the river. I planted 40 willow sticks around the edge of an old concrete electricity pylon base rising out of the mud. As the trees grow over the coming years, I’ll attempt to ‘weave’ them into a green structure & create a living building.
