Incense Cedar
A western North American conifer with flattened sprays and aromatic wood. Despite its common name it is not a true Cedrus; established trees can handle dry summers on suitable deep soils.
Calocedrus decurrens · Western evergreen conifer
Profile
- Foliage
- Flattened scale-leaved sprays.
- Cones
- Small elongated cones with a few distinct scales.
- Planting
- Set the root flare at grade and protect the expanding root zone from compaction.
- Assessment
- Confirm identity, local climate suitability and drainage before prescribing care.
Water & soil targets
- Moisture (VWC)
- Site-calibrated; varies by soil and rootstock
- Salinity tolerance
- Prefer low-salt irrigation.
- Drought tolerance
- Good once established on suitable sites.
Optimal root measurement depth
8–18 in
Most absorbing tree roots live in the upper 12–18 inches, out toward the drip line. Typical guidance; confirm with a soil probe on site.
Water to establish a broad root system, then use spaced deep irrigation in severe drought; avoid saturated collars or repeated shallow lawn watering.
Problems to watch
- Incense-cedar rust
- Bark beetles in stressed trees
- Root disease
Stress signs
- Brown shoot tips
- Crown thinning
- Branch dieback
Where you'll find it
- Large native landscapes
- Screens and timber plantings
