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?

    I have 4 foot wide mulch paths between my raised beds. If I were to rake the mulch over and put a tarp down under it, would that stop them? I know some plants effectively give up after they go a certain distance.

      No. They go a looooong way underground. I don’t know if it was the same plant, but I’ve seen new patches pop up a couple dozen feet away from known patches.

        That’s sad to hear, but thanks for the information. It sounds like I’ll be digging up the pathway around this bed annually.
