Needing help to remove Knotweed from behind home on a sloping lot.

Does anyone know how bet to do this or if there is a landscaping company that would tackle this.

Thanks

HaHaHaHaHa. HaHaHa. Oh HaHaHa.

Sorry scouser (Hey – are you a Liverpool or an Everton fan?) If I don’t laugh I will cry. Knotweed is a cruel mistress. She’ll likely taking more than simple removal. I’d look into taking the programme via King County so that you can borrow their injector gun: http://www.kingcounty.gov/environment/animalsAndPlants/noxious-weeds/weed-identification/invasive-knotweeds.aspx

We’ve been battling it for several years. Good luck!

There are only two teams in Liverpool. Liverpool and Liverpool reserves. :)

Thanks for the help

You’re a top one in my book then! Whilst all the family back home cried about losing Stevie, I’m so excited to see him play against the Sounders.

goats?

they will eat everything not just the knotweed but that will give you a head start for the next round

Unfortunately there is laurel mixed in and this is poison to goats, so that is not an option.

Kimberley, I also will miss seeing Stevie playing for Liverpool, but like you I am looking forward to seeing him at Safeco Field.

I hate to say it, but spray the crap out of it with Roundup, then do it again. And again. And again. If you hit it really well when the plant is in flower, you’ll get about an 80-90% die off the next season (as in, much less will come back and the root system down there will be really weak). If you can fry it right before it winters over, you should be able to get it under control the following year. It’s NASTY stuff, so if your neighbors aren’t controlling theirs, you’ll have a much harder problem keeping it gone. I got mine pretty under control in one season, but I was not conservative with the poison. I felt bad about using it, but it’s sort of the only way, unless you can steralize the soil.
