We want to plant seven Hetzii columnaris junipers for screening, and I want to stagger them rather than plant in a straight line. The variety descriptions say they should be planted in a "tight row". The mature diameter (average) is 5'. How close should we plant them? Would 4' trunk-to-trunk be too loose? Also if anyone knows where 6' size (12 gal.) can be purchased in the Atlanta vicinity for less than $200 each, I would be ever so grateful for the information!
Spacing for Hetzii columnaris junipers
Check out this publication from UGA. http://www.caes.uga.edu/publications/pubDetail.cfm?pk_id=7850 And this from Monrovia. http://www.monrovia.com/plant-catalog/plants/1613/green-columnar-juniper.php It has a link to search for retailers near you. Neither link says how far apart to plant though.
