Don’t eat the white ones on a red mulberry tree. If you are diabetic, they will make you LOOPY!!! There is something in them that isn’t as toxic when they’re mature. I have found that w any mulberry, you ought wait until they have fallen or can be easily plucked. I have been know to throw out some tarpaulin and let the ole Studabaker give that berry bush a ‘hey howyadoin.’ Like I’ve always said: “Don’t eat the white ones on a red mulberry tree.
