Monterey Cypress
A coastal California cypress adapted to mild maritime conditions and wind exposure. Inland heat and drought can increase canker problems; mature trees develop broad crowns and need ample room.
Hesperocyparis macrocarpa (syn. Cupressus macrocarpa) · Coastal evergreen conifer
Profile
- Habitat
- Restricted native coastal groves on California’s Monterey Peninsula.
- Form
- Often wind-shaped with a broad crown, unlike narrow Italian cypress selections.
- 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
- Tolerates coastal salt spray; root-zone salinity remains a separate concern.
- Drought tolerance
- Moderate in cool coastal climates; less dependable inland.
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.
Provide establishment water and occasional deep moisture in dry weather; prioritize a mild suitable site and drainage rather than constant irrigation in hot regions.
Problems to watch
- Cypress canker
- Root rot
- Large limb failure
Stress signs
- Brown flagging branches
- Resinous cankers
- Crown thinning
Where you'll find it
