interior yellowing.. and eventual browning of older interior needles is entirely normal .....

it can be increased in the year of planting... perhaps the second year.. if not properly watered until established ...

and it can also be increased by harsh weather .. either a summer drought.. or a windy cold winter ...

and its very common with larger transplant ... just too much stress ...

focus on the growth tips... and until they brown... you are fine .. or the tree is .. lol.. i dont really know about you ...

i think its a chamaecyparis .... rather than the common name of cypress ... but i might stand corrected by our friends ... it might matter to avoid common names.. when using a search engine ...

It's a Hinoki false cypress, Chamaecyparis obtusa. Some interior browning is normal but IMO, that much browning is excessive. I use these a lot in my designs and collect them personally and when I see that much brown foliage, it is an indication to me that something is not right.

How long has it been planted? Have you checked the soil moisture level next to the rootball? My first guess would be some sort of water issue - too little or too much.

@gardengal48 (PNW Z8/9) yes it is a hinoki cypress. It has been raining here for whole week. I am not sure if it is the problem. I also see the needle tip brown not only the interior. Is there anything that i can do to save the tree? One of my fav

@gardengal48 (PNW Z8/9) it was transplanted from last spring. It had been growing well to me until weeks ago.

@ken_adrian Adrian MI cold Z5 thanks Ken. It is a hinoki cypress, i see tips turning brown too. like the ones in this picture. Can i still save it?
