Hi all, I'm planning on building some raised beds this year and i had the idea to build them from some trees that fell on my property. I thought they were Juniper but they are identifying on a plant app that i have as red cedar. Are there any trees that would be dangerous for me to use to build a raised bed? I know you can't cook over certain kinds of wood logs because they can poison the food but i didn't know if this would apply to building with it as well. Any thoughts?
