You might check out in the Lancaster area. Most of the local nurseries are fairly expensive except for HD or Lowes. Check the PA forum, there are a few entries about Lancaster nurseries. Have you tried Russell's Gardens off Second Street Pike in Richboro? They may be able to help you?

I would love some. I have lots of stuff gathered up for the swap!!

ya know.. when you get down to basics ... a thuja is a thuja ... shop price based on ultimate size.. and then maybe color ... e.g. a smargard .. emerald green.. is going to stay rather shortish .. with a nice green color .. GG is going to be a giant ... with some winter bronzing.. which i like ... so if spring grove has the giant potential ... and you can buy what you want cheaper than GG .. then whats the difference?? .. other than perhaps.. color??? or as dave notes.. density ... you want a tomato .. [why i dont know] .. so you go to the store.. do you want a bunch of minis .. or one giant one ... buy what you can get.. for the right price.. they are all tomatoes ... there is a thuja called wakehurst.. i think .. mine is planted about 450 feet from my GG .. and frankly.. i cant tell them apart .... though i have never cut off a branch and carried it from one to the other to check ... ken

I love walls of emerald green arborvitae, especially their texture, color, and fullness/density. Here is a pic I took about an hour ago at Muirfield golf course(Memorial tournament). Love the wider spacing, this is gonna be a killer wall in 10+ years(road is to left of bike path, need to focus on putt). Looks like they disregarded the internet, which generally suggests 2’-3’ spacing for wall, when deciding on spacing(check out the dead one). If Jack Nicklaus approves Thuja Occidentalis Smaragd as a privacy screen, then they must be good lol. Id say 21, 5-6 footers for 850 is a good deal. Still small enough to “become one with the ground/established” rather quickly. Even the 10+ footer I planted 5 years ago did good, though the smaller the tree, the quicker they get established. I have seen tiny tots outgrow larger trees on more than one occasion. I didnt believe what people were telling me until I witnessed it. All the $5, 1.5-2 foot Smaragd I planted 4-5 years ago are gettin close to 5’, some might be more. In looking at the pic, and knowing that there are lots of deer here, (some of) these may be getting deer pruned, though just a bit. The right two perhaps.
