Raspberries are escaping their raised bed after two years :( I really don’t want them to spread beyond it. what to do? Bury a tarp under the mulch? Dig a trench around the bed? Roundup?

Just grab them as low to the ground as you can and pull them out, taking as much root with it as you can. The plant will focus its nutrients and efforts on the sections not being torn out. Any time you see another escapee, grab it and pull. They will become less frequent as the main body fleshes out and grows.
Nature doesn’t like bare empty spaces so consider filling in that large empty barked area with some more crops and raspberry escapees will have some competition and become less likely as well.
I hadn’t considered spot weeding. I guess I don’t have a lot to lose and will give it a shot before trying something more drastic.
Our raspberry bushes only send up runners early in the season. It is pretty easy to just pull those who escape.
I am going to try pulling runners this season and see how it goes. I think the mother plant kept creeping across the raised bed all of last season, but maybe it will stop being as vigorous in the summer.
We have a raspberry in our bare soil and we only had to pull a few in the spring. Good luck!!!
