Just taken over an allotment thats is completely choked with the weed...
My idea is to plant in raised beds which I will dig out to about a
foot deep then put some weed suppressant down then backfill with the riddled
soil that I have dug out...Anyone tell me if this weed suppressant fabric
will keep the mares tail at bay or does it have the power to grow through

I fear it will laugh in the face of the matting and has little more
trouble with concrete and tarmac, but there are folk on here who have got
rid of it so hopefully you will get some useful advice
