Cypress Mulch Overview
Cypress mulch sits between hardwood and cedar in both price and performance. It resists decay and insects better than hardwood, holds its color longer, and mats together well to resist washing in rain. Cypress is particularly popular in the southeastern US where it's locally harvested.
One consideration: the environmental impact. Old-growth cypress forests in the Gulf Coast have been heavily harvested for mulch production, raising sustainability concerns. Look for mulch labeled "cypress blend" (mixed with other woods) or sourced from plantation-grown cypress rather than old-growth harvesting.
Apply 3-4 inches deep, same as other wood mulches. Cypress holds moisture well -- in very wet climates, 2-3 inches may be sufficient to avoid waterlogging.
