What is compost mulch?

In light of this, is compost and mulch the same thing?

If they're both so important, what's the difference between compost and mulch? Mulch is any material put on top of the soil around plants to help keep in moisture and shade out weeds. On the other hand, compost is a mixture of decomposed organic ingredients.

Against this background, why would you not want to use compost as mulch?

We don't use compost as mulch however. Compost is full of nutrients that we want to get down in the soil to feed the plants through their roots. In contrast, mulch is the layer of organic materials placed on the top of the soil as a protective cover.
