New York State Honeyberry Conference

June 29, 2024
8:30 am - 4:30 pm
Mexico, NY

Join CCE Oswego and CCE Harvest NY for a state-wide conference on a new emerging fruit called Honeyberry, also known as Haskap (Lonicera caerulea). Honeyberries are a dark blue color, like blueberries, but with a distinct oval shape. The taste is most associated with raspberry and blueberry, while also containing its own distinctive flavor. The fruit can grow in USDA Plant Hardiness zones 1 to 8 and can survive up to 30 years or longer if properly managed. What makes the fruit unique is that it ripens from the middle of June through early July. This allows the fruit to sit comfortably between the strawberry and blueberry season. When fully mature plants can produce 6 to 10 lbs. of berries, which can be eaten as a fresh fruit or made into value-added products.

The conference will cover the history of the fruit, best growing practices, processing, value-added production, and marketing. Guest speakers will include growers and researchers from the US and Canada, including Dr. Bob Bors from the University of Saskatchewan. Attendees will also be able to network and attend an optional farm tour immediately after the conference. 


Field Guide: Arthropod Pests of NYC Vegetables

Arthropod Pests of NYC Vegetables aims to help urban farmers and gardeners find, identify, and understand the most common and important insects and other arthropod pests found in New York City farms and gardens. Some of these pests are rarely mentioned in other guides but are common in NYC. The guide emphasizes scouting tips, including how to identify pests by the damage they leave behind, even when you can't find the insect itself.

This guide was created as a collaboration between Cornell Cooperative Extension's Harvest New York team and the New York State Integrated Pest Management Program.
