Cedar tree with browning tops

Question

Attached are 4 photos of my beloved cedar deodor tree. I spent $1,000 to “save it” by having the top half cut off. Now the needles keep turning brown lower and lower. There do not seem to be any bugs involved. We have used nematodes to get rid of slugs/grubs. My heartfelt thanks for your help. Gloria Stanley
