Tom Cook, retired OSU turfgrass professor, has published a new book detailing the construction and maintenance of sustainable landscapes! The book includes topics such as sustainable landscape design, how to develop an ecosystem, issues regarding the use of chemicals, and approaches for modifying existing lancescapes.  The book can be purchased from Amazon: Sustainable Landscape Management: Design, Construction, and Maintainence!

Introduction

Maintaining a healthy, aesthetically pleasing lawn depends on many variables including turfgrass species; mowing height and frequency; fertilization; and insect, disease, and weed control. Proper irrigation, despite being one of the most important factors in maintaining a healthy lawn, is the most often overlooked variable in lawn care (figure 1).
