Thanks to all who responded. I really like the mulch fungi route and yes it is a good time to bring permaculture to the young ones. I have been doing a lot reading and have found that round-up also kills worms, we have been teaching vermiculture with the children and they love their worms so I am thinking of doing "worm monitoring "in the beds as well as building things back up. It will be a good lesson for all as this is the generation that will be one that has to clean up so much destruction. Thanks again to all my fellow permies!
