It's a normal cycle all cedar trees go through. Here's how it works: around late summer or early fall, cedars and most conifers need to let go of older, interior needles that are no longer doing the tree much good. Those needles turn yellow/brown as the tree phases them out and makes room for new growth from the tips.

How do you keep cedar from turning brown?

Be sure to always keep cedars healthy by watering them during completely dry weather. A deep complete watering once or twice a week is better than light, regular watering.

What does it mean when cedars turn brown?

Young, recently planted cedars will show stress, manifested as browning, if you move them around. Cedars of any age can brown if you don't irrigate them properly. Prune dead foliage during fall when the tree is dormant. Learn how to detect and prevent destructive insects that can cause your cedar to turn brown.
