Q.putting rhubarb to sleep for the winter
I planted Rhubarb crowns this past spring. Did not harvest anything. They look very healthy. We have had two frosts but they still look ok, a bit wilted. I will cover with compost for winter but do I just leave the stalks and leaves on the plants through winter or do I cut them down? If I need to cut them down how much should I take off?
When the leaves have been hit with hard frost I like to remove the branches.
You certainly can cover the crowns with a bit of mulch, this will aide the plant incase the snow doesn't fall right away for insulation.
Here is a link with more information.
