I have never had a rhubarb problem before but now it is terrible.
I bought 2 bog potted plants last year, got them both in, only one made it through the winter, the nursery replaced the dead on so I started off with two again. The new one didn't even start to take off it just withered away, the other one which started to grow is puny, the sticks are less than half an inch and it looks pathetic.
Any other rhubarb I have ever had seemed indestructible. I can't figure it out. It doesn't get the sun all day.
