Red pecan shells are brought in directly from farmers in southern New Mexico and are a great way to celebrate New Mexico agriculture in style. Pecan shells are a great alternative to gravel in xeriscape design. Using pecan shells rather than volcanic rock can reduce evaporative moisture loss and may help keep your yard a little cooler during the hottest days of summer. Municipal projects across New Mexico are replacing volcanic rock with pecan shells because of their advantages for sustainability, and you can too!
