Question
My rhubarb has finally taken off, now how do I winterize it for northern Minnesota winters? Do I cut or pull the stakes? I have not used it as I was told not too for the first year. Help, please

Answer
Dear Sally,

Rhubarb needs cold to trigger spring growth. Rhubarb tolerates cold temperatures (-20 degrees F) very well. Cut the last few stalks after the first hard frost and throw them on the compost pile. Then spread a layer (3-5") of compost, leaves, or straw) to prevent winter winds from drying out the roots.  Also, watering is important especially if drought conditions are prevalent during the winter months.

Rhubarb is as hardy as vegetables come. They will begin to grow as soon as the ground begins to thaw. No matter hold cold it gets in late spring, the weather will not kill the plant, although in some cases it may damage the first leaves.

Sincerely,
