Cedar trees may change color in late summer as a natural adaptation to seasonal changes. This is normal, especially for newly planted hedges.
Seasonal Color Change - "Augusting"
- From late August through September and October, it's normal to see cedar foliage turn yellow or brown.
- This natural process, called "Augusting", happens as temperatures drop and nights become cooler.
- Growth slows above ground so the tree can focus energy on root development and winter preparation.
- In some cases, up to 50% of the foliage may change color. This does not indicate a problem.
- New growth in spring will naturally replace fallen leaves.
Recommendations
Watering
Continue watering during dry periods until the end of fall.
Fertilizing
Do not fertilize at this time. New growth before winter can be fragile.
Patience
Let nature follow its cycle. A well-"Augusted" hedge is better prepared for winter and will come back strong in spring.
Important
Seasonal color change in late summer and fall is a normal part of cedar development and winter preparation.
