Do all shrubs love ericaceous compost?

No, not all shrubs love ericaceous compost. The compost in question offers amendment, fertilizer, and mulch possibilities to shrubs (and other woody, as well as non-woody, plants) that favor soils whose pH measures in the acidic range. The Word ericaceous references plants in the Ericaceae family, commonly called the heath or heather family even though it includes such even more famous plants as azaleas and rhododendrons.
