Re-Planting
  • On December 21st
    • Planted 14 Hybrids to fill in spots where trees had died or failed to emerge.

Future
  • We plan to plant another 100 trees next spring from new lines, and if all goes well another 100 trees the next year


  • After their 3rd year of growth the trees will be inoculated with the blight fungus


  • Trees lacking resistance will be destroyed, but trees showing resistance will be used to advance the breeding program
