We have brambles, bindweed and couch grass roots all over our new allotment. I'm not sure my plan is the best and would appreciate any advice with regards to the weeds under the paths. This is my plan at the moment:
Dig (with fork) the entire plot removing as many roots as I can by hand.
Mark out beds and paths
Cover over the path areas (which will have been dug, weed roots removed) with cardboard and walk on the cardboard to flatten the soil again.
Cover cardboard paths with wood chip
Re-dig beds incorporating compost
The reason behind digging the whole plot is to try and remove the weeds from the paths as well as the beds, as I do not want them spreading into the beds later.
But ... I'm pondering ... is this necessary? Will the brambles, couch, and bindweed die from being covered over or will they, as I'm assuming at the moment, grow under the cardboard and woodchip into our veg beds?
I don't mind doing the digging if it will have a positive effect but don't want to waste my time doing it when they would have died anyway?
