As I think I mentioned a while ago, shortly after we moved into Symbolic Towers we noticed a vinelike plant spreading itself rapidly over the garden trellis. None there at all when we moved in, but within a couple of months the trellis was covered. Bindweed. It seems to be endemic in this part of Bristol: you can’t go anywhere this time of year without seeing its foliage and its white trumpets clogging up fences and doing their best to strangle other plants, particularly in semi-wild areas like the edges of railway lines. We’ve spent a lot of time tracing every stalk, and digging up every little bit of bindweek rhizome we could find; carefully, like archaeologists, to make sure we didn’t break the rhizomes up or leave fragments behind. It has mostly worked: a few stems have come back, but only a few, none of them very strong. On those, we tried a method we heard on Gardeners’ Question Time: singing and blackening the leaves. It worked, too, sort of, although (of course) not as effectively as physical removal.
I was aware, of course, that things could have been far, far worse. Moreover, I was reminded by a news story K came across, about Japanese knotweed. It reminded me of the advice I read in (I think) an Alys Fowler book: if you have knotweed, move house. There are knotweed-infested places in Bristol – Arno’s Vale cemetery, for one, and some parts of the riverbank in St Philips – and, if we visit any, we are always extremely careful not to go near the stuff. Over-careful, maybe, but it’s not something we could exactly risk.
