Grrr. Even Roundup won't shift this long thin Spiney weed

Hi all, Roundup/ glyphosate is not effective on marestail. I use Verdone lawn weedkiller to weaken it. As others have said already regular hoeing keeps it down. Good luck, Rae.

Use Kibosh weedkiller from Progreen ( Google them) It kills it stone dead in one treatment.

And in the spring, when the fruiting bodies form (these look like small tightly closed pine cones on the top of a straight shoot) go round and break every single one of them off and burn them.

Incidentally, don't use the same shoes and tools on this stuff that you would use on your allotment (if you have one) or to work in a friend's garden. Don't pass plants, soil or cuttings from your garden around. Don't take soil from your garden or the shoots of this stuff to the council recycling or composting either. Burn any shoots of this stuff you remove, don't put it in your own compost bins or even in your regular rubbish. In other words, impose a quarantine on your garden. No-one is going to thank you for passing it on to them! My SIL had this on her allotment site and we lived in fear of it getting transferred to my allotment site, five miles away. It's not terribly evil stuff as in you can grow crops along side of it but it is unsightly and you'll never, ever get rid of it once you have it. The roots go about ten feet down and it's been on this planet since the dinosaurs.

I thought this until about 3 weeks ago. My garden was infested. I've used Kibosh on it and it has all gone!

I'm extremely pleased
