The plants look very strong, have almost 18" diameter leaves and it is late July. Do we leave the stalks in for the rest of the summer? Do we pull the stalks or cut them so the roots can develop for next year? We are in central MN so it is hot now and we have cold winters. We also have some tan colored leaves on a few stalks like they are dry or beyond season - should we pull those stalks out?

Go ahead and cut and discard any old and damaged leaves and stalks.
If the plant has lots of stalks, go ahead and eat these. Just make sure you leave some stalks on the plant to feed the crown so that it has energy stored to survive the winter. Let it die down naturally as the fall arrives.
