I made a garden bed in my yard one half is flowers other half is scallions and tomatoes will mulch hurt plants?

Will red mulch kill my garden plants???? I hear there good and bad let me know I have flowers too and onions and scallions growing the mulch is pulled away
so your telling me that only tomatoes and peppers will grow in red mulch beds?
