Hi Peony, rhubarb is darn near bomb proof!
On one allotment plot we had there were rows and rows of rhubarb which all had to be dug out and dumped. There must have been over 100 crowns dumped in a pile - our new allotment neighbour had a few. What happened next year?? It all grew!!
No soil, not planted, but the darn stuff grew again and our neighbour couldn't be bothered to plant his and that grew aswell. When you dig the crown up get the spade and force it through the middle of the crown to split it - then you will have two rhubarb crowns!
