A late April freeze might seem like a single bad night, but what we’re seeing across Pennsylvania orchards is a season-long management puzzle. Kari, Shan, and Greg outline what's important in a challenging year.

Don, Kari, Greg, and Shan walk through the overnight freeze and the chain reaction it triggers across fruit set, disease risk, and insect timing in our  orchards. We share what to scout first, what to spray only when it makes sense, and how to protect pollinators while the weather keeps changing.

Don is joined by Kari and Shan this week to discuss what happens what a spring freeze doesn’t just “nip” buds. Shan highlights what to do after the frost: how to sample across a block, cut buds to spot real freeze damage in the reproductive tissue. Kari gives an early fire blight heads-up as warm weather accelerates bloom, plus a smart “minimal spray program” mindset for blocks that lost fruit to winter injury.

Don, Kari, Greg, and Shan dig into stone fruit losses and disease timing as a warm spell pushes early peaches toward bud swell. We outline what early scouting actually tells you and how to get ready for oriental fruit moth and codling moth. If this helped sharpen your spring plan, follow the show, share it with a grower who needs timely cues, and leave a quick review so more orchards can find us.

We welcome our new pomologist, Dr. Sara Serra, and dig into how pruning, harvest timing, and vision tech can raise fruit quality across apples, pears and peaches.  The Mid-Atlantic Fruit and Vegetable Convention begins Jan 27. Registration available on site. Winter Fruit Schools run Feb 10–19 across regions.

Don, Kari, Shan, and Greg unpack the season’s rollercoaster: a soggy May that drove scab, rust, and bitter rot risk, followed by a dry, color‑rich harvest window. We lay out infection windows, what worked for Honeycrisp, why alternate row coverage backfired, and how to prep smarter for next season.
