Mexican Sunflowers

Question

I’m a first time grower of sunflowers. What should I do in the fall? Will the plants come back next year?

Answer 1

You should definitely harvest the flowers right after they die. They will usually be eaten by animals and won't have a chance to re-grow. Collect these and replant next year.
