Now that the leaves have fallen, we begin to prune Catawba grapes. We begin with Catawba since they are more winter cold hardy than some of the others. The vines in this vineyard were somewhat overcropped this year so the reference vines averaged a little more than one pound of cane weight per plant. Using the 30 + 10 pruning formula recommended for Catwaba, that means we need to leave 30 bud per plant. We are looking to leave five 3-bud spurs on each side of the bilateral cordon.
