The Principles of Pruning
Many of the state Extension Web sites have information about pruning, but another source is the Corona Clippers site. It offers a free 25-page Principles of Pruning PDF. The booklet covers the basics of pruning many kinds of ornamentals, including trees, shrubs, roses, broad-leaved evergreens, hedges, vines, fruit trees, and berry fruits.
Although long out of print, The Rose Book, by yours truly (Rodale Press, 1994), costs only pennies from online used book sources. Providing information for growing roses organically, the book also gives in-depth information about choosing from among the thousands of roses available and using them throughout the landscape. In addition, the book also covers using fresh roses in bouquets, as well as how to dry roses and use them in crafts and body products.
