When can I cut back rhubarb plants?

Question:

When can I cut back rhubarb plants?

Answer:

Don’t cut back the rhubarb until the foliage and stalks have been destroyed by a hard freeze.  To produce a good crop next spring, rhubarb plants must manufacture and store adequate levels of food in their roots.  The foliage continues to manufacture food as long as it’s healthy.  Once destroyed, the foliage and stalks can be removed.
