My matilija poppy is quite tall and gangly. I left au naturale it last year and the branches got very top heavy. Should I be trimming it down somewhat? If so about how much should I trim?

You can trim them when the new growth starts to come back after flowering. It won't hurt them to trim them pretty hard, as they are known to spread quite rapidly. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/flowers/matilija-poppy/matilija-poppy-care.htm
