This fall will be my third harvest of Pinot Noir grapes. One vineyard test I forgot to perform last year was a petiole analysis. Basically, you take the leaf opposite the lowest bunch at bloom and test its composition. From that you can see if you need to make adjustments in your sprays or fertilization program.
As you can see from above, I’m in pretty good shape…just have to add a little boron to my foliar sprays. My analytical goal this year is to harvest amazing fruit with a pH of 3.5X…wait and see in 3.5 months if I got it right!
