Hey everyone.
I’m really struggling with this weed! I dug it all out and covered with thick mulch just to find it creeping through again :(
Any advice would be hugely appreciated!
Thanks,
Andy.
Well Andy that's grass. It is a runner type of grass, most likely couch and will be difficult to get rid of by just pulling it out as the stems will snap off and leave parts in the soil to grow again - as has happened for you. Mulch will be no deterrent. Really the only solution is glyphosate spray which will kill the whole plant, roots and all. So Zero, Roundup, call it what you like, this is the only sure fire way to get rid of runner grass. Wear a mask when spraying and it will be safe as it will bio-degrade within a few weeks. This is what ForestInfo of California have to say "Glyphosate is highly susceptible to degradation by microbial organisms (bacteria and fungi) in soils, water and sediments and also readily dispersed by plants and thus considered to be non-persistent in the environment".
