Arbor Vitae Trees Turning Brown - Knowledgebase Question

I planted some arbor vitae trees about one year ago.

3 of them are about six feet, and the rest of them are about 3-4 feet in height.

The six foot trees are really turning brown, and the 3-4 foot high ones are turning brown as well.

what I should be doing to nurse these back to health?

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!
