HELP! Sick rhubarb!
The stalks of one crown have gone very soft and are collapsing. At the base there is white froth like what we always call "cuckoo spit" . I haven't investigated to see whether it has a little creature in it.
The rhubarb was moved (only a yard!)last autumn when I widened the bed. In forty years of trouble free rhubarb growing I have never seen this before. What is it and how do I stop it spreading? Last year's crop was excellent.



Sounds like some kind of canker or rot has got into the crown, possibly bacterial - does it smell? I'd remove the crown and inspect it thoroughly, and dispose of it (not on the compost heap) if the whole crown is soggy and rotting.

Thanks Bamboo. I wouldn't have thought of that. I've been down on my knees and its doesn't smell bad - just pleasantly loamy. But maybe I damaged the crown when I moved it - in fact thinking about it, I'm pretty sure I did. Its not easy to get right down and remove the whole root without breaking it.
Looks as though that bit's had it then - I will dig it up and have a look.
