Both contain macro and micro nutrients that perlite lacks.
What is the cheapest way to improve soil?
Adding homemade compost or well-rotted farmyard manure is a cost-effective way to boost soil structure. Make sure it’s dark and has no smell – if it isn’t rotted down sufficiently, it can scorch roots and leaves. Adding some form of organic matter to the soil each year is a good garden practice.
