Should you put mulched Oak leaves on flower beds? Are chips from pine trees good for mulch? Third question how much black dirt can you add to existing flower beds?j

Oak leaves are fine as are wood chips, if chips are mixed into the soil nitrogen should be added since they use it to biodegrade.
If you are starting a new flower bed, you can add as much black dirt as you want, if this is a existing bed several inches should be fine but don't mound it around plants.
