The N Factor: Orchard Sanitation & Nitrogen Needs Explained

In this episode of Between Two Rows, Erika and Kristy dig into the N factor - how nitrogen shapes tree growth, fruit quality and orchard health, tackling two grower questions: What is the nitrogen demand in an orchard? How can urea be used as a disease management tool? First, we explore orchard floor management and supporting sanitation strategies to breakdown overwintering apple scab. We walk through how urea works, when to use it, and how it fits alongside your regular fertility program. Then we shift gears to how trees actually use nitrogen, and what happens when they get too much... or not quite enough. Whether you're planning nutrient budgets, thinking about fruit set, or looking for tools to reduce disease pressure, this episode connects the dots between nutrition, disease management, and timing - all in one conversation between two rows.

Bitter Truths & Blight Fight: Calcium Pathway & Fire Blight Management Explained

In this episode of Between Two Rows, Erika and Kristy dig into two grower-submitted questions: What is calcium's role in bitter pit? Is there an ideal time to manage fire blight? First, we explore the calcium pathway - how calcium moves through the tree, why fruit is often the last to receive it, and the role this plays in the development of bitter pit. Then we shift gears to fire blight, tackling the question of whether there really is an "ideal" time to manage this devastating disease, or if timing depends on orchard conditions and seasonal risk. Join us as we break down the science and share practical insights - all in one conversation between two rows. Featured cider this episode: Loch Mor Cider Co.
