So this past week I noticed that the arborvitaes that line my back fence were turning color. I did some reseach for the symptoms but the description of "a disease" doesnt match whats going on. [But highly possible I am missing something]. I also looked for insect larvae but I couldnt point out any - looked for grey spots, molding and split trunks but none of those seem to be an issue.
It seems the inner part of the tree is getting brown - the leaves inside the tree are brown (dead) and there are a few of them that are yellowing on the outer leaves.
I want to think it's because we had a 2 week dry spell with scortching heat while we were away - so of course it didnt get any water. Do you think that watering will bring them back healthy?
Please take a look at the pictures and try to help me out here. It would be greatly appreciated.
