Dear wine grape and muscadine industry colleagues: I am hoping harvest has been over long enough now to ask y’all for a favor… and, in return, you will receive a tool that will be helpful and evolve over time.

As a follow up to yesterday’s post on scouting your vineyard for system disease and/or nutrient imbalance symptoms… Grapevine tissue (leaf blades and/or petioles) sampling is a good, objective indicator of nutrient status in your vineyard.
