Hello and thanks for reaching out to Ask Extension!

Inner needles on cedar trees brown seasonally in fall, therefore if this started recently, this may be natural seasonal change. Year-round or rapid browning indicates serious distress, such as root rot, drought, or pests addressed below.

Cedar trees commonly suffer from browning foliage, branch dieback, and root rot caused by stress, poor drainage, or pests like leaf miners and spider mites. Key issues include drought, winter injury, and fungal diseases (blight, rust). Management involves proper watering, pruning, and consistent monitoring.

A dying cedar tree often exhibits widespread browning/yellowing, starting from the top or outer branches and moving inward. Key signs include brittle, dead twigs, bark that is peeling or splitting, and a lack of new growth in spring. While inner needles brown seasonally in fall, year-round or rapid browning indicates serious distress, such as root rot, drought, or pests. If you are concerned that the tree looks stressed from top down or you have a lot of dead branches and peeling or splitting bark, you may want to submit your question and the photos to the pest lab <personal data hidden>. They may ask for a sample to id if indeed the tree is stressed by disease or pests.
