Chips and Shredded

This mulch is made from pond cypress trees and bald cypress trees. Both the back and wood of the tree are ground up to make cypress mulch, and the mulch is available in either chips or shredded cypress. The shredded is the better choice than chips because it stays in place longer and composts faster. Shredded cypress mulch is also cost-effective, making the cypress mulch less expensive than other organic mulches.

Nutrients and Microbes

Cypress mulch decomposes to add nutrients to the soil, while some mulches such as shredded newspaper do not. Most plants benefit from these added nutrients from cypress mulch. Some organic mulches such as pine needles and pine bark change the soil pH as they decompose, thus adding acid to the soil and lowering the soil’s pH. On the other hand, cypress mulch is neutral and doesn’t change the soil’s pH as it decomposes.


Cypress mulch is an attractive ground cover than other wood mulches such as pine bark, cedar bark, and shredded hardwood mulch. It also has a fresh, pleasant smell when it’s fresh. Cypress mulch weathers to a soft, gray color, a property that is often considered a valuable attribute. While other mulches might blow away, cypress mulch, especially pine bark mulch, tends to float away after heavy rains. Therefore, it will not need to be reapplied, unlike other mulches.

The mulch has a high capacity for holding water, preventing the available water from seeping below the mulch. When the cypress becomes dry, it repels water instead of absorbing it. This prevents water from reaching the ground below the mulch and the roots of the plants.


Cypress mulch tends to wash away more easily than other mulches. This makes it a bad choice in areas subject to heavy and frequent rains. When it’s also saturated with water, it becomes heavy and does a better job staying in a place, making you replace it more frequently than other mulches.
