I look forward to reading the results on tapping below the lateral lines. I had asked Dr. Tim about this a few years back and he said they were doing a study on it. This season I tapped over 1000 trees below the lateral lines. Some were 12-16 inches below. I had a record season for GPT this year. My overall production was .4+ for the season but that is great for me and my smaller trees. My sugar average for the season was just 1.5%. Had it been 2% like some sugar makers I would have had a .54 GPT season. I feel I'm doing as well as I can with the trees I have to work with. All 1000+ trees I tapped below the lateral line was with CV2 spouts.
