Mulch

* An organic mulch is very important to our landscape’s health here in our typically dry and poor soil climate. As briefly described above, organic mulches provide several benefits. They over time will help to improve soil structure by helping to create an organic layer or horizon in the soil profile. This is important because this is typically the most efficient layer of our soil in terms of moisture retention and nutrient exchange potential.
*In addition to the above mentioned benefits, mulch helps to retain moisture during the summer months when conditions are hot and dry. It will also provide an insulating layer during winter months to help borderline hardy varieties over-winter more successfully. A word of caution though about this is that if the mulch layer is too fine, it actually can hold too much moisture around the crown of perennials during winter months and rot them out instead of protecting them.
