Hi all. My Rhubarb plant is about four or five years old and am wondering if I should split it and if its the right time of year to do so? If and when I do I'll be struggling to find room for the 'new' plant. Will it grow in shade? I know down the road from me in the Rhubarb Triangle they grown it in the dark by the light of candles but will that work for me??? Seriously though I have a shady section of garden under some big Castor Oil & Laurel/Bay bushes/trees would it cope under their canopies?
