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.
