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.

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.

Never pick the stems in the first year is a rule I was always
told, but one root I transplanted some of was so vigourous that
I decided to go ahed and crop - lightly. That cropped well the
next year as well.

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.

Early days yet, in the colder parts of the UK rhubarb are just coming
through

Never heard of any infections in rhubarb, but always a may be!
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.

I know Rhubarb can be prone to virus but its more likely something has
been eating the roots, (check for vine weevil)

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.

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.

I don't know. 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!!!

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

Sounds to me as if they need a good helping of farmyard manure.
