Help please!
I have aquired a piece of land that I intend to grow vegetables using the no dig method, but the area has been neglected for many years, but i have discovered that a large part of it is covered with poison hemlock. will I be able to proceed with my plans and cover the ground with cardboard without taking any other measures? will the hemlock roots adversely affect any crops if their roots reach out beyond the cardboard and mulch?
since identifting the problem last summer I have tried to keep the area under control with a brushcutter and the lawnmower whilst I worked in other areas of the garden, suffering a nasty burn to my leg at one point despite wearing protective clothing.
My plan is to start on this section as soon as the weather allows me to get on it so any advice would be gratefully received.
