Hi All
I have tried growing Coriander this year after being very successful last year, unfortunately the chickweed seem to have taken over and I have decided to cover the soil with weed membrane and build a raised bedding over it and put new soil/compost and grow Coriander in the raised bedding.
My question is how deep does the raised bedding need to be? I want to keep it as shallow as possible. Would 5-7 inches deep be enough?
Thanks
