A Commercial Horticulture Newsletter for Landscapers, Arborists, Garden Centers, Turfgrass Managers, and Property Owners!
For 35 years, Hort Notes has provided timely, research-based information to Green Industry professionals on the latest control strategies for insects and diseases of woody ornamentals, as well as weed management, alerts about current pest outbreaks, and educational opportunities. UMass Extension ceased printing the hard copy version of Hort Notes at the end of 2015 and transitioned this publication to being available exclusively online.
Since 2020, we have also combined aspects of Garden Clippings (our horticultural newsletter for home gardeners) with our Hort Notes newsletter to provide one-stop shopping for all of your educational needs!
Hort Notes is written for landscapers, grounds managers, arborists, and other green industry professionals with the understanding that home gardeners may also look to this publication for information as well. This newsletter includes monthly email alerts to emerging landscape insect and disease problems while providing timely Integrated Pest Management strategies and emphasizing timely plant health care practices and problem-solving information.
