You have to set up a Photo Gallery and upload the pictures to your Gallery. You cannot post pictures from other sites until you put them in your Gallery. Here is a link on how to do it.http://www.forestryforum.com/board/index.php/topic,23851.0.html
The java uploader will resize them for you. Clearly you did not take the time to watch the video tutorial. if you can't put the photos here by taking the time to learn how to do it, then You are out of luck. I'm now being blunt because after being told about the rule, you insist on trying to find a way to circumvent it.
Keep them watered, and keep the neighborhood dogs away from them! Dog pee is bad for them. If you are in an area where you get freezing winters, mulch around the bootom of the trees, and if you have rabbits or deer, they think they are candy bars.
They are evergreen, but evergreen does not mean that the tree will not shed or not have some seasonal die back of some needles/leaves/foliage. I think the die back you have there looks typical of the trees we have. The trees will do well in the northeast. I would not water the trees anymore now. Just try to protect them from the critters and look for the new growth in the spring.
Needles on an evergreen tree, like these cedars, only live for a couple of years, then they die and are replaced with new needles. This is a natural process. What you have to looks like for the most part the normal Fall needle cast where the older needles have reached the end of their life. Totally natural. I did see a branch or two that look like that it had died, but most of the needles looked normal. Sit tight, protect them like Jeff said, and check them again next Spring. You are likely OK.
Hello Hydrangea and welcome to the forum! I hope that you will stick around, there is so much you can learn here. I'm from the Philadelphia area (Chester County) and you should put that hose away for the winter. The ground is completely saturated in our area. I'm in complete agreement with Jeff and WDH on the normalcy of the condition of your arbor vitae and methinks that the Home Depot guy just wanted to sell your something to "fix" the problem. If the appearance of those brown spots bothers you, put on some work gloves and you can run your hand down the limbs to gently pull them off. Don't be afraid to prune out the dead limbs. As long as they have mulch around them, they should winter just fine.
Did you keep the tags from the trees? Arbor vitae is usually eastern white cedar or western red and are Thuja species. I believe yours to be western red, just from what I could Google quickly. Some of the trouble could be hotter climate in your area, the trees may be burning up. I can't say that for certain, but there is a reason they are northern tree. Adding fertilizer reduces PH and too much can burn them, not what you want. Newly planted trees are not usually fertilized for a season or two. I would be more inclined to add lime in the fall of the year (like now) to get PH up. Also, planting and handling has a big impact. Trees in containers have higher survivability, since roots are not subject to drying out if kept watered, where as burlaped bare roots that are sitting in mulch can loose a lot of finer feeding roots because they dry out quickly. You can also get an air pocket in the planting spot that dries out and kills roots by not filling the hole and firming it up around the roots. You do not want to compact the soil too much or plant too deep, this can smother the roots. It appears that you may have some combination of these where the trees have not been able to grow enough new roots in their new home to take up enough water to keep the foliage from burning up. I think a lot of the brown you see in Jeff's images are from the cones. At least I see a lot of ripe cones on his tree.
