Today I attacked docks and marsh grass with the ditch blade. Found a very wet patch down near river in NW so dug a hole 2 spade blades deep about 5m in from fence and it promptly filled with water. Clay at the bottom so could be a possible site for a pond. Dug out a bit more to see what happens.
Just planted in seed tray in the tunnel Nasturtium, Melon, Ridge Cucumber and Aubergine.
