Rhubarb woes
Of my 3 rhubarb plants, all grew fairly well to well last year, but two of them have put up only a few spindly shoots this year. I assume that I have to start again, but is that likely to mean that I need to get new stock (as distinct from taking offsets)? Regards, Nick Maclaren. |

I assume that I have to start again, but is that likely to mean that I need to get new stock (as distinct from taking offsets)? Depends on the age of the roots. Mine usually last about 5-6 years before needing to be trimmed back - I tend to break off side offsets without disturbing the whole plant if possible. I left behind two large plants that had been cropping well for at least 15 years when I moved. Say, 5-6 years, and I did exactly as you said. My question is whether I should regard the two weak plants as potentially infected (or whatever). I can't see any evidence of that, except for the small number of spindly shoots.

Assuming you did not force the crowns, which always weakens them, I would leave them alone, but not pick any stems this year, unless they get really well ladened. Yes, I forced them, but did that to the strong plant, too. I don't think that there is much point in giving them another chance. I know Rhubarb can be prone to virus but its more likely something has been eating the roots, (check for vine weevil) Or the growing tips. If I dig them up, I will check. Vine weevil is unlikely here, because it doesn't like frost much, and I have never seen it - but it's only one of many such pests. Regards, Nick Maclaren. |

I have never had anything other than vigorous growth out of mine on a heavy clay soil. It gets forced most years but then left to its own devices when we get fed up with rhubarb. Last year was a bit peculiar with the warm weather as the unforced plant had new shoots on Xmas day sufficient for rhubarb crumble!!! -- Regards, Martin Brown |

I live in the far north of Scotland where winter temperatures regularly reach -15C and we have a real vine weevil problem.
