Winter is coming and I have three milkweed plants that I need to winterize. I have mulched but do I need to cut the stems down to the ground? Each plant is a single stalk--leaves are now brown and dry and look like they will drop off the stalk. Thank you! BJ. (Bend, Oregon)

Some milkweeds are perennial and some are annual. If yours are perennial and they are winter-hardy in your climate, then they will be fine either way, and once the leaves are completely brown, you can either cut the stem or leave it there over the winter.
