Some people say that cypress mulch is rot- and insect-resistant and that it doesn’t float away. Is cypress mulch better than sustainable alternatives?
No, the perception of cypress as a wonder wood persists from a time when lumber was produced from old-growth. The truth is today’s cypress harvested for cypress mulch is usually younger, smaller trees that have not had the time (hundreds of years) to develop the decay and insect resistant properties of older trees. For example, melaleuca mulch is better at keeping bugs away, and pine straw stays in place better than cypress mulch. Sustainable alternatives to cypress can satisfy gardeners’ mulching needs.
