Hi

I was surprised by some advice in this weeks Spectator page 20 from the

broadcaster Jonathan Dimbleby:

"Beware of knotweed conmen. You don't need smoothies in Range Rovers,
white boiler suits and goggles who charge more than your house is worth

to get rid of the stuff. The weedkiller Roundup does just as well for a

fraction of the price."

Can this really be true?? I have always heard that it's nearly
impossible
to get rid of!

Has anyone on here actually tried it? I've never heard of it actually
working...

Yes. I cleared an overgrown back garden over two years. I attacked the
problem in late summer early autumn by lopping the tops off and
pouring a little glyphosate solution into the cut stems. Almost all
the crowns were dead next year and those that put up some growth
succumbed when I sprayed them when I expanded the treated area next year.

Of course the real problem is getting rid of it _all_ which can be a
problem if it comes from over the fence.
