Bonsai Nut
Nuttier than your average Nut
I was kinda hoping to hear from the people that had to dig a big lawn juniper , boxwood , azalea, etc. at the wrong time because the owner wanted them gone. I've seen some monster junipers dug that I would be very curious to see if they survived.
I have had to move some large landscape junipers in the middle of the summer in SoCal. The key is to protect the foliage until the roots can recover. Landscape junipers can survive in SoCal without supplemental watering - once established - but need irrigation for the first few years.
When collecting California junipers from the desert, the excepted "best practice" is to use a humidity tent with frequent wetting of the foliage. Since the humidity tent is made from some type of plastic, it is important to not allow the foliage to rest against the plastic, or that part of the tree will usually molder and die.
I was unable to use a humidity tent on the landscape bushes (about 4' in diameter) so I wrapped the foliage balls in burlap (completely), and watered them twice daily. The burlap cut the sun by 75% or so, while still allowing the tree to breathe, and the wet burlap, combined with the wet soil at the rootball, provided humidity. I waited until I saw new growth sticking through the burlap, and then waited about another month or so until the winter rains were approaching before removing the burlap. I have used this method three separate times and not lost a tree. Like everything else with bonsai (and conifers) it requires patience. I kept the burlap on the trees for about six months, give or take.
