How did you care for it in the three weeks before planted and the two weeks after?

Brown tips on leaves of many plant species can be due to under watering but I’ve never grown a pine like this. I’m guessing it’s in a pot since you moved it. Potted plants usually need daily watering (however many factors come into play here, like the size of the pot, whether it’s in direct sun, ambient temperature and of course species of plant) as pots dry out much quicker than ground soil. It may do better in the ground if you can’t dial in it’s watering needs in a pot. Just make sure it’s meeting its light requirements if you do decide to transplant it.

it was stressed form shipping from grower to seller

it was stressed from moving from seller to your house

it was stressed from planting..

you stressed it again by un planting it ...

wait for it.. its stressed ... stop stressing it ...

note that new growth was just fine.. and this was older leaves.. and that is stress related.. if not also winter damage ... increased after stress...

i dont understand where it is now.. back in the pot??? .. i might just leave it in that pot until fall ... water properly.. which means let it near dry in between waterings ... keep it in full bright shade for at least a month ...

and pretend you never read about some random disease process.. its stressed ...

ummm... also.. if this is the gold version... its supposed to be yellow .. wonder how sure that label name is ...

and.. its a conifer.. a tree ... it will not stop growing in your lifetime ... so place it appropriately ... with room for lots of future growth ..

this is how i look for an idea of future growth potential ...

While it was in the pot, before planting, it was in 6 hrs of sun and checked daily to see if it was dry and needed water. In the ground, full sun, I checked for water needs every 2 days. I’m putting in a new garden area of dwarf conifers and Japanese acers so had a number of new plants to monitor. The delay in planting was waiting on a landscape company that was to put in 3 larger trees after we lost 5 trees in an ice storm in February. I’ll just say there were issues.
The Carsten’s Is in a pot now in bright shade and I check it daily. Wintergold is yellow only in winter like Chief Joseph and some other pines, I believe. It had a gold tinge to it when I got it. I’ll include a photo from 4/18/21 when I brought it home.
Stress makes perfect sense. The plant does look better today with new growth shooting up. I’ll keep it in the pot, in bright shade, until fall and check it daily (2” into the soil) to see if it needs more water. Thank you for all your help.
