Hi. I have some sick looking trees in the back yard. I've tried fertilizers for years and things are just getting worse. They are in 2 clusters and are maybe 10-14 feet in height. Pictures attached. Any thoughts on what they are and what to do? Thanks so much.

They may be Arborvitae. Poor drainage could do this - Arborvitae don't like wet feet. Is your soil compacted clay? If you do have clay, salts from the fertilizer may be building up in the soil due to poor drainage.

You don't say where you live. Does it snow? Is that the level of the snow?

Whatever the problem, your trees haven't managed to put down a good rooting system.

Does the fence go all the way around the garden? Just wondering because that's what arborvitae look like when deer have eaten the lower part of the plant. The green areas at the top would be above munching height and are wider than the brown. I would go easy on the fertilizer as Daisy says, if you use too much the salts can damage the plants and also make it harder for them to take up water. Plants like that don't need much, if anything, in the way of fertilizer.

Does the brown go all the way around the trees or is it mostly on one side? I notice the lawn looks a little brown near the trees as well.

Is that a swimming pool behind them? If so I'm also wondering about chlorine damage.

That's deer damage - or similar hoofed browser with limited reach.

Look at the rest of the trees above the brown parts - the top halves is turning brown also.

My first thought was deer damage as well. I see this growth pattern all the time in my area. I do like how they are clumped in a bunch rather than the straight lines one so often sees. Good luck.
I want to live in a world where the chicken can cross the road without its motives being questioned.

I noticed that too but sometimes they will stretch to reach bits that are too high to reach easily, but only get a little bit off compared to where they can just stand and munch, so I wondered if that could explain the lesser damage above the solid brown
