Hmm. I thought there might be additional wise words
and I saw something to this effect on crocus or somewhere, including the suggestion of limiting spread by making a barrier in the soil?
I've been gathering bookmarks and thinking about this. I know what to do
there's a corner of my garden still infested with a collapsed garden shed: no roof, window fell out, walls are leaning, blah blah. It blocks a neighbour's view of my side return, though ie it gives me a great deal of privacy. Jerusalem artichokes sound like they'd be ideal there. It's next to my love/hate laurels, there's a 4" diameter dead silver birch there too (which I left standing in case I needed to chop it down for firewood if the grid collapsed, there's plenty for them to hang on to. I could also dig a trench (gradually!) and fill with ... something ... to isolate them.
Possibly not explaining it too well (and I've only just thought of it
). I'll delay the tuber purchase till next week, but the whole "easy perennial that grows food" is very attractive to me, and gives me something useful to do with that corner, rather than just tidying it up. Ha!
Jenny, hope this is useful to you too
