Can you eat wild onions and dandelions in your yard?

I recently picked some wild onions, the ones that look like scallions/green onions. I cleaned them up and they look good to eat but are they? Also, I know that dandelions are sometimes used in herbal stuff like teas and salads. Are those the same dandelions you find growing in the yard [...]

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?
