New York and New England Management Guidelines for Greenhouse Floriculture and Herbaceous Ornamentals
Cornell University produces a joint New York/New England guide for the integrated management of greenhouse floriculture crops and herbaceous ornamentals. The manual presents biological, cultural, and chemical management information for insects, diseases, weeds, and plant growth regulation. The guide also includes management options for outdoor production and maintenance of herbaceous perennials.
The 2026-2027 Guidelines will not be available until after this year’s NE Greenhouse Conference. We expect them to be for sale from the Cornell Store on November 17, 2025. Please click the button below on or after this date for the new edition.
The Guideline is available in two formats:
Print Copies are spiral-bound for ease of use, feature laminated covers for durability, and are updated annually. $47.50
Online Access versions can be viewed on any computer or mobile device (e.g., smartphone, tablet), contain hyperlinks to additional resources, and may be updated during the growing season. $47.50
