Broadleaved Shrubs and Shade Trees 

Problems, Picture Clues, and Management Options

(NRAES-183)

 

Why didn’t my azaleas flower this year? … Why is my maple tree showing its fall colors in July? … What’s been chewing little round holes in the leaves of my roses? … What’s causing those unsightly brown spots on the flowers of my prized dogwood?

The answers to these questions and more can be found in a guide recently published by NRAES.

After observing the problem in a shrub and shade tree, the reader will then follow the guide’s easy-to-use, photo-based problem key to zero in on the cause. Management strategies are suggested for most problems. The guide will be a valuable resource for home and master gardeners, students, educators, and horticultural consultants. It will also be a useful addition to garden-center bookshelves and landscape-oriented mail-order catalogs.

Features of the guide include:
•    Pictures and descriptions of over 125 abiotic problems, diseases, insects, and more.
•    430+ color photos
•    180+ pages
•    Introductory chapter on diagnostics and nonchemical management strategies
•    Photo-based key to symptoms and possible causes
•    Compact, spiral-bound design with laminated cover
