KLETŦ, J.E. 1988. Crabapple evaluation update. Colorado Green 4(3):12-14.
Crabapples have a long history of evolution which was led to the rise of over 700 variety and cultivar names. However, many of these have never been properly described and some of the names are not taxonomically valid. Therefore, the Department of Horticulture at Colorado State University, Fort Collins, elected to participate in a national research project. The department is one of 20 sites cooperating to evaluate approximately 50 different crabapple taxa for disease resistance; fruit color, size and retention; flower color; form and specific growth habits. This study also will help standardize crabapple descriptions on a nationwide basis, and ultimately provide guidance to homeowners and members of the green industry through publication of an easy-to-follow procedure for the best selection of the crabapple for a given application.

The questions concerning guying have perhaps created more controversy over the years than in any other area of landscaping. In an attempt to clarify some of the controversy, Colorado Green conducted a survey of landscape professionals to obtain their preferences in these areas. It was the concensus of our survey respondents, that the make-shift and marginal products of yesterday should be discarded for the newer products that have been specifically designed for guying trees. The initial costs of these products may be slightly higher, but that is far outweighed by their reliability, safety and ability to be reused.
