Pine straw is quickly moving up the list of must-use mulch options. For years we have used it at Peter Wimberg’s home, completely blanketing the front landscape and its gentle slope to the street. After the perennials are cut back in late fall, or simply left as is, we cover the landscape with a generous amount of pine straw. Unlike hardwood mulch which can become compact after the winter season, pine straw remains loose enough that ‘fluffing’ is not required come spring.
