@Attmos
The contest is a Native Tree in a Native Pot. No treating the wood. It wont last too long.

OK. So they aren't to be considered for permanent use.
Beautiful piece of wood, by the way.

It hasn't earned a real pot yet It's Native tho.

Well his buddy had a tuff spring... early May. Old needles looked a bit ratty but new green tips popping and healthy

Late may nice extensions still looking good.
But Mid July going down hill. Treated for mites a week or so prior. And weekly since.

Lower right branch self defoliated.

We had a hot spring like most. Kept in my tree house under shade.

Looking for suggestions. Considering putting back in the grow bed for a year or two.
His partner in the log is looking good.

Any suggestions?

Any suggestions?

Not from me but it doesn't look good. lol

Nice backyard setup.. very peaceful.

Same thing happened to me (actually worse) due to too much sun. I moved it to partial shade. Next year recovered fine.

I was going to suggest the same- looks like sunburn, or maybe not enough water. I bet the one in the log retains more water. These guys love cool, moist conditions- kind of remind me of hinoki in that respect, though hemlocks can take a lot more shade.

I have one in the ground that seems to be struggling with too much sun. Might move it to a shadier spot in the spring.

I never had a problem with too much Sun, though my test subjects are dropping 1 by 1 in S.C., but I think it is lack of a proper cool season rather than too much sun. I moved a couple under the bench, because they were so weak, and that was the final straw and they gave up.
I do think it is good to think of them as shade tolerant, rather than shade loving.

But I think something else is killing off hemlock other than adelgid. A fungus maybe? Seems kind of like tip blight.

Thanks to all for the replies. They have both been in the same protection from wind and sun in my treehouse shown above.
It has been a crazy hot spring/summer... the log probably does hold more and insolate.
I'm retired and always home to monitor watering.
I'ma throw in the shady grow bed under the benches and hope to see improvement before winter.
TY folks

the damaged leaflets will not recover. As long as you see next years future buds forming, you can expect to see healthy fresh flush next year. I think its less about sun/shade and more about root temp. I think hemlock like cooler, consistently moist roots. The naturally grow and excel in locations near water, mist, and protection.
