It's hard to say based on the picture alone. A lot of bushes and small trees in our Michigan environment are dieing as a result of last summers drought and this winters cold. They just didn't get enough water through those times to build their reserves to come back this spring. In addition to that we've also had some severe frost cycles this spring that have added further stress to our plants. In future drought conditions please try to supplement your plant's water needs. You might also check the roots for good healthy creamy color. If they are healthy appearing they might be salvageable with a little judicious trimming away of the dead appearing foliage. Gold Mop Chamcyparis is also one of my personal favorites. Good luck with further investigation of the root zone. Thank you for using the Ask an Expert System.
