We inherited it in my brothers garden and I dug as much as I could out. It took up most of the beds and by digging and removing as many of the roots as I could we have really cut out most of it now. It still springs back but has a hard job competing with bigger species planted over it. I don't use chemicals and just keep digging it out when I see it as I think it's far easier.
Glyphosate works by being absorbed by the leaves when they're in active growth. Zapping white roots will have little to no effect at all, I'm afraid to say.
Good luck 🤞
I agree, if you're going to use glyphosate (or any systemic weedkiller) you need to apply it to the leaves when the plants are actively growing. The effect isn't immediate - it takes a few weeks for it to be absorbed down to the roots, so don't be too quick to pull off the top growth after applying it - leave it a few weeks to work properly.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
I'd talk to your neighbour on the other side of the wall and agree a joint plan of attack. I wish I had £1 every time I heard. " sorry about those weeds. They come from next door" to which I normally reply. " I bet that's what they say too? "
You've all given me so much to think about. I try to avoid chemical use because I have a blood condition and find that garden chemicals excacerbate it. I love gardening (all except this plant!) and I might first try to do what the victorian suggested - if that doesn't work it'll be back to glyphosate I'm afraid. It really is such a pretty plant, but like the apple in Snow White - its growth habit is poisonous!
My sister has spent all this week digging it out of the front border at her new house. She has a 4 year plan. Went to the garden centre for lunch today and they are selling it for £10 a pot.
The borders at my brothers house were riddled with it and we do still get it popping up from time to time but if you are able to dig it out then that's what i'd try first. I'm happy digging stuff and it's easy to see because the roots are a thick whitish colour, so spent a winter doing it. It can go fairly deep but it's not to bad if you use a fork and have moist soil (our is sandy so doesnt clump, if you habe heavy soil it might make it very hard to deal with). It is a massive amount of work but we are down to just pulling the odd piece up now and it doesn't seem to spread as it's been knocked back. The only downside to digging it out is it runs at the root so can pop up in your new planting. It's fine if it's tough plants but it can be a major pain in the bum if they are more delicate.
