Hiya, I hope you can help me rescue this tree, many thanks for any advice you can give. I bought this Cupressocyparis 'Gold River' spiral in May, we then had a super hot June and now my tree looks like this. There are still green tips but the majority of it is brown. Is there anything I can do or is it lost? Thanks

Thanks for your comment on your brown confided after heat damage.
Unfortunately once a Conifer dies back to old wood that brown wood never recovers. Similarly if you had prune a Conifer too much back to old wood it stays brown.
The reason Conifers stay brown when damaged or hard pruned
Conifers have limited capacity to recover from old wood because their growth occurs mainly in the outer layers of the tree, particularly the cambium layer, which is responsible for producing new cells.
As conifers age, their cambium layer becomes less active, and the older wood in the inner part of the tree becomes nonfunctional and unable to support new growth. This limited ability to regenerate from old wood is one of the reasons why conifers often do not recover well from severe damage or pruning in their older parts.
So the best advice is to compost this plant and start again I’m afraid. Ensuring they don’t dry out in the future.
