marestail warfare

[snakeshack]

now have two lasagne beds I started as an experiment when I got my allotment in september,am trying an anglisised version of three sisters on them.
marestail for height with convulvulous growing up it and couch grass for ground cover.
glycophosphate doesn't touch the marestail and I have been pulling and hoeing the stuff out for 10 weeks ,it seems reduced in the spud beds but not where the brassicas are despite a heavy liming last autumn

What, buttercup?
I don't get it in my beds, I get it on the bark paths - I'm not liming my paths, lol

Thats fair enough, but why not put a membrane beneath the bark. That should stop the buttercups coming through shouldn't it?

On the other hand, maybe because its on the paths and not in the beds your not that bothered about it. As long as you lime your beds it I'd have thought it would stay clear of them.

Thats fair enough, but why not put a membrane beneath the bark....maybe .... your not that bothered about it.

No, I'm not that bothered. It would involved a lot of expense, and a lot of digging up of paths.
I was simply making the point that buttercup likes acidic soil (bark is acidic) and doesn't like dry alkaline soil (my beds).
