In my garden, I head-cane prune my vines. This was either 3th or 4th leaf. 2nd year of production. This spring I tried for 8 lbs per vines. Ended with up with over 10 pounds per Lomanto vine. I plan to keep it around 10 per vine.
Your BS should be identical to my favorite. 2011 favorite was 8lbs per vine, 24lbs Total from 3 vines. 2012 numbers I'm estimating at around 16 maybe 17. I lost some very nice bunches. If you include them, about 18-20 this year. Plus one of my favorite vines had barely any grapes. Estimate 2 clusters per bud. Favorite clusters weight about 6-10oz.
