You need a lot of tap root in order for them to survive. Since they are so plentiful and cheap, it's better to cut them down instead of transplanting. You can get some that are 6 feet tall for about 30 bucks at your local big box store.
BigBill said:You might have another possibility. If they are multi trunked beautiful specimens perhaps you could donate them to a local nursery. They often get jobs where these plants might be just what a client needs to put up a " living fence" or barrier on their property. It might be worth a landscaper or nurserymans time to come in with the appropriate equipment to dig them out and transplant them.
Rather then just cutting them down it might be worth a shot. Just don't expect any money in return or replacement plants. It will cost them time and effort to remove them.
Bonehead said:Or would it be possible to prune them back to a manageable size? I don't have much experience with arbs, but it seems I see them in tidy little rows quite often. Might be worth having one of those tree arborist people come out and give you a bid on managing their size. My brother-in-law bought a house with a nice mature row of arbs between his back fence and a rather messy farmer which he promptly cut down, and has spent time/dollars trying to rescreen. I can only shake my head...
