does anyone have blackberry, raspberry, or oak trees on their property that I could harvest some small branches from? (must be pesticide-free, for pet food)

I’m adopting some stick bugs and their diet consists of mainly plants like blackberry leaves, raspberry leaves, oak leaves, and rose leaves. it would have to be completely pesticide-free and herbicide-free, as they are highly sensitive to it.

my goal would be to propagate the branches (except for oak, as I’m not sure how well that would work).

I tried to post earlier asking for recommendations as to where to find them in nature, but asking for recommendations aren’t allowed on this subreddit, so I’m asking for a favor instead lol. thanks for reading 🙂
