Q.Emerald Green Arborvitae Brown & Green
We planted 20 trees approx. 2ft. tall in March ’18. All of them are starting to look like they are going to die. We had lots of rain over the summer and not once did we need to water them manually. We are experiencing a rather rainy season.
We need your help, please!

They do need plenty of water till they are well established. But their roots do not like to sit in soggy soil. Is yours a well drained location? I imagine you have lots of humidity there and that can lead to fungal problems such as blight, which is controlled by pruning out the affected branches and starting a fungicide routine.
I suggest calling your local extension service where they can give a more definitive diagnosis with more information.
