Hi, Carpet is banned at our site so we use slabs. Keep eye open for drives being replaced and the contents of skips. You'll be surprised what you can get. Digging out is the only real way to get rid of pernicious weeds like mare's tail and bindweed. We have some creeping over from a vacant plot next door. We've sunk slabs down the edge of the plot edge deep which slows the stuff down a lot. Hard work but worth it. Hope you have a really great season.xx
We followed a mare's tail root down through sandy sub soil for a distance of over 3 metres and never did reach the bottom of it, so be warned. We also saw a root going down the side of a quarry for over 30 feet. Not the easiest thing to dig out.Sorry, but eternal vigilance and a good hoe are the best things.
I just used to hoe the new stems off as and when I saw them, that is every day as I went out to go to work. Took about 5 years but in the end it did go away. Don't ever let them spore though.
