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.
