Rock is allowable, but not recommended against a structure as it acts as a heat sink and can increase the ambient temperatures around your home by 10 degrees or more, thus creating higher cooling demand on your air conditioning system. Rock mulch radiates heat around the root system of your tree or plant, creating a stressful growing environment. The weight of rock mulch will also contribute to soil compaction.
