What kind of soil is best for growing asparagus fern?

Asparagus fern (Asparagus setaceus) thrives in a warm, humid soil environment rich in humus with good permeability, so whether the soil mix is good or not often largely determines the growth condition of the asparagus fern. If you can prepare a high-quality potting soil that is fertile, loose, breathable and well-draining, then you have provided a good physical foundation for growing asparagus fern well.
