as with all irrigation.. we can not tell how its all working on your yard.. your soil.. and your location ... btw.. where are you ... big city name ... how was winter???

how about some pix ..

in the meantime ... take a hand trowel or tablespoon and dig 3 to 6 inch holes around a bunch of the plants.. along the irrigation run ... AND FIND OUT about miosture at depth... adjust watering accordingly ...

a bit more history other than the brown parts might also help ...

imo.. trees never need fert in mother earth... what did you apply.. and how much ... a little of this or that is usually not a problem ...

Hey Ken.

I'm not in a big city. Im in a small town in Alberta, Canada in zone 3a a quick drive from Edmonton. We had a fairly regular winter...I don't see any damage on the foliage this year but the last two years, I had some sun browning of the south side of a couple of my cedars that are placed in between manitoba maples that are 40ft tall and some browning tips on some of them that are beside large spruce trees.

We had a major drought two summers ago and I didn't give my cedars enough water. Last summer, we had buckets of rain after 2 months of drought in spring. A couple of the cedars who were struggling last spring, now look great and some of the nicest looking ones are starting to look bare (ones besides very quick growing spruce trees). Its a struggle with the cedars that are close to the mature trees in my yard. All the cedars are also 4ft apart and are supposed to make a hedge.

We live in a semi-arid climate with very sunny and cold winters. I know its not the cold temps though as exposed cedars I have are fine and its only the ones that are near large mature trees that are getting burnt (I'm guessing from a lack of water in summer which leads to desiccation in winter).

Thuja on the west coast see upto 6x the amount of rain I have and 3 to 4x the amount on the east coast native ones.

I just bent it down to show you the difference between the yellow and green growth. Quite a few trees are showing this and never used to and it’s literally only the leader.

Anyone?

I can't keep 'em alive, so I got nothin'. Sorry

If the bronzy tips are soft and supple rather than dry and crispy then they aren't necessarily damaged

Some are getting brown and crispy. Its only one or two leaders though and everything else is nice and green. Lots of good growth too. So odd... Nice response Lane. I remember you telling me that lol.
