cedar mulch does nothing for the soil. it is incredibly slow to decompose and the process of decomposition requires nitrogen. the nitrogen ends up coming from the soil.
the ideal choice for mulch is pine/spruce bark mulch that is aged already. it is already somewhat composted and therefore breaks down faster and adds organic nutrients to the soil.
it would be better if the amendment to the soil were actually compost rather than screened loam. compost usually does cost more though, but, is much better for the plant material.
finally, in our garden beds, we will use compost as a mulch because it is so much better for the plant material and the soil. we have clients that prefer to have the best at any cost though.
good luck with you rbid.
