Different Types of Mulch and their Unique Uses Mulch can be used to create micro-climates, extend the season, prevent weeds, create pathways, retain or release water (and prevent washing out when you get too much rain), protect and improve the soil, prevent soil-borne diseases...

Creating a buried pot garden is a beautiful and easy way to ecoscape. Not only will your garden be extraordinarily charming and tidy, it'll consume less water and energy. Sunken planter gardens like this one provide both form and function. The pots prevent your herbs or plants from overrunning their designated areas, and the mulch keeps unwanted weeds and pests at bay while consuming no water and energy.
