An Important Pruning Reminder
Mario Miranda Sazo, Cultural Practices
Lake Ontario Fruit Program
Cold hardiness is the ability of a plant to withstand low temperatures. Low temperature injury after a pruning cut can vary depending on when the low temperatures occurs (early vs. mid- or late-winter), how fast the temperature drops after the pruning cut, what the temperatures are the few days before and within 10-14 days after the pruning event, and how long the low temperatures are sustained in the orchard. Young trees are more sensitive to cold snaps after pruning than older trees. For those of you who produce fresh fruit we recommend you start pruning your older trees and the most resistant cultivars to winter damage first. The most resistant cultivars like McIntosh should be pruned now leaving the more sensitive cultivars until after January 1. Do not start your pruning of Empire, Red Delicious, Golden Delicious, Jonagold, and Mutsu at this time of the year just because you have the time and/or available labor force. Cutting done at this time (particularly making large chainsaw cuts) can predispose trees to winter injury if temperatures drop rapidly in the next couple of weeks. Hold off all pruning of most sensitive cultivars until trees have time to harden off under more cold weather. The more sensitive apple cultivars to winter damage after a pruning cut are: Golden Delicious, Red Delicious (more sensitive), Empire (more sensitive), Jonagold, and Mutsu. The apple cultivars with an intermediate susceptibility to winter damage after a pruning cut are: Paula Red, Cortland, Gala, Idared, and Greenings. The apple cultivars with less sensitive to winter damage after a pruning cut are: Honeycrisp and McIntosh (all strains).

Good Agricultural Practices (GAPs) Training & Food Safety Plan-Writing Workshop
February 2 - February 3, 2023
Newark, NY
Goals of this workshop:
- Understand how GAPs (Good Agricultural Practices) impact produce safety, and how you can improve practices on your farm to reduce the risk of microbial contamination
- Learn the difference between a FSMA Inspection and a GAPs audit, and learn what is needed to have a USDA GAP/GHP audit and the 2 types (Basic & Harmonized)
- Begin writing a farm food safety plan that complies with a USDA GAP/GHP Audit
This workshop is targeted at Mott's growers who need to have a successful GAP audit for the 2023 harvest. However, all farms and organizations are invited to attend.
We will have several breaks, including a lunch break, scattered throughout the day, but feel free to step away whenever you need to. Lunch and snacks provided. Note: All times are approximate. Time spent on each topic varies depending on audience and questions/discussion. There will be time for questions at the end of each section and a final opportunity for questions when we close for the day.
Instructors Confirmed: Craig Kahlke (CCE-LOF), Robert Hadad (CCE-CVP), Caroline Boutard-Hunt (CCE-Yates), Judy Wright (CCE-Seneca), and Representatives from NYS Dept. of Ag & Mkts.
How Profitable Will My New Orchard Investment Be? 1-day, hands-on skills class
February 7, 2023
Highland, NY
The Eastern NY Commercial Hort Team and the Lake Ontario Fruit Team are offering a 1-day, hands-on course at 5 locations in NYS in January and February for tree fruit farms on using farm financial information and other resources to make decisions about long-term investments or changes to their business. We will apply the techniques covered in the 8-part webinar series in December to scenarios using sample financial data from fruit farms in NYS.
