Tender roses for tough climates1997

"Roses are the most popular plants in North American gardens, yet more cold-climate gardeners have trouble overwintering roses than any other flower. Through a decade of trial and error at his nursery in Canada, Douglas Green has developed a totally new method of growing roses, one that is guaranteed to revolutionize this popular hobby, making it a rewarding pleasure, not a frustrating chore. Where all previous rose guides have been based on methods developed by 18th- and 19th-cantury European gardeners, Green has discovered made-in-the-North techniques that allow almost any rose to grow without hilling or winter protection of any kind. They Blossom year after year, disease- and pest-free, without recourse to inorganic chemicals." -- Amazon.com.
