Note that Cypress mulch is now considered 'not green' since Cypress trees are being destroyed to make this.
The best choice for mulch at least in Florida is 'Florimulch' which is made of the invasive Melaleuca tree. It may also say 'Eucalyptus mulch',
I have been using this for a couple of years now and like it a lot. It is the same price as the Cypress mulch.
