I planted four 5 ft. arbor vitae next to each other this past spring. The 2 in the middle are turning brown. Do I just keep watering them or are they a lost cause?

It's difficult to diagnose a problem without being able to inspect the plants. If the browning is on the outside growth as well as the inside foliage, I'd suspect a water stress issue. Droughty conditions can cause foliage browning, but overwatering or poorly draining soils can actually suffocate the roots and the foliage will turn brown as a result. Be sure the soil drains quickly and don't forget to water them deeply once each week. Wish I had more to offer!
