I'm in NJ and the soil is sandy in my area. I also added Miracle-Gro
Potting Mix with Fertilizer 1/2 bag per plant.
They were all in pots and they didn't store them well. I don't think
if they were close to any road way before I got them. What I do know
if that about 2 weeks after I purchased my thuja all thujas (about
6-8) at my Lowes were dead - brown and dry.
I worry because I don't see them getting any better. We did have few
heavy rains here in NJ and I if the watering would be an issue I would
notice something after 2 days of raining. I'm gonna get Ortho 1 Pt.
Systemic Insect Killer from Lowes and see if that helps.
I do have 1 year warranty on them but it took me a week to plant them
all. I don't want to do it over again.

As I mentioned in a previous post, trees in pots are generally safer.
However,
these trees could still have been dug improperly out of the ground and placed

into pots with too few roots. I have been reading where nurseries are going
over to raising trees in pots. The challenge there is to move the trees to
bigger
pots, if they outgrow their current pots.
