The petiole is the stalk that joins a leaf to a stem. At LDV Winery we periodically take petiole samples to check the grapevines health. The sample is sent to the lab for analysis. The report we receive assists in determining if we need to add nutrients or trace elements to ensure healthy grapevines. We take petiole samples three times during the growing season: shortly after budbreak, after flowering, and during grape formation. So far this vintage, the vineyard has a great fruit set and the vines are very healthy. Fingers crossed the vineyard continues to evolve and remain healthy.
