Bindweed in my Raspberry patch

[Harry]

Advice, please.
I have a patch of long established and pretty neglected raspberries. Unsure what species, but I've been advised to hard prune them for fruit in autumn. Last year, they got pretty much smothered by out of control bindweed, which eventually died back along with the raspberry foliage. The raspberries are just about starting to bud again, but I know there's lots of bindweed rhizomes lurking.
So.... Am I too late to remove and move the raspberries to newly prepared soil, so I can attack those weed roots.
Or is there another way I could suppress the bindweed.

Plot is also plagued by marestail, but that's not so prevalent in the raspberry area.

I think probably you're just on the edge of it being OK to try to move your raspberries, depending upon where you are and how far advanced your season is.

It's difficult to move raspberries without causing a lot of disturbance as the canes and roots go quite deep. Prepare deep holes in advance and dig well down.

In that sort of situation you could hedge your bets and move half perhaps, and try to get on top of the bindweed in  the vacated stretch, then next year move the other half earlier.

My raspberries, summer and autumn, are permanently bindweed infested. The years when I tackle each shoot as it appears, and get out as much root as I can, then i keep on top of it, but sometimes it gets ahead of me, ties all the stems together so I have to cut them apart to get at the fruit - but actually, it doesn't seem to have any bad effect on the plants or their growth. I'd be much more worried about the mare's tail if I were you, horrible stuff.

Unsure what species, but I've been advised to hard prune them for fruit in autumn.

Cutting them back all the way is a good method of determining whether they are a primocane or floricane variety, but won't guarantee you fruit in the autumn. They will only fruit in autumn if they are a primocane variety.

This is a tricky one as even mulching heavily won't guard against returning bindweed, and it always finds a way around suppressant. You might just have to chance digging the whole lot up and moving to a clean well-prepared row. Personally I'd opt for this - even if I lost 50% of the transplants I figure the initial reduced crop would be better than the yield and time lost to competing weeds year on year.

(If you do move them, double check to make sure you don't take any sneaky pieces of bindweed rhizome on the rootball.)
Good luck :)

Some thoughts:

How well are the canes growing and fruiting? Are they worth saving or is it better to put new canes in a clean bed?

If there are spaces between clumps or you are clearing out some in order to move those, try putting a layer or two of cardboard down with wood chips or other mulch on top. In my experience, bindweed doesn't get through that and any bits that come up at the edges can be trained away from the canes and sprayed (the only weed I do that on).

You can move canes at any time, cut them back and they will re-establish but you may not get fruit that season. They tend to come up as bare roots, so that helpfully minimising the chance of transferring any bits of bindweed root.Do the cardboard / mulch tactic on the new bed.

I need to get out and do that with my own raspberries which have Jerusalem artichokes, nettles and brambles in them.
