I am thinking maybe 5 to 7 foot spaceing the smaller of the 2 hedges will be all HC the larger will be a mix up of MvsB,RdB, and sal'g. my single florea cutting had sudden cutting death sydrom.
the other that will need some winter protection for at least a ffew years i will put ing the small orchard spot in the back.
the smaller of the 2 hedges rns north to south between to large pine trees and gets enough sun for the HC as i already have one planted there doing well. not sure if it will get enough sun for the others.
