Southern Live Oak
Southern live oak is a broad-crowned coastal oak of the southeastern United States. It retains its old foliage until new leaves emerge and needs substantial space for its spreading branches.
Profile
- Crown
- Broad-spreading crown with gnarled branches.
- Leaf retention
- Old leaves persist until new leaves begin emerging.
- Acorns
- Acorns mature in one growing season.

Species and soil references do not establish universal moisture targets, monetary appraisals or pest diagnoses. Missing pest lists mean evidence has not been verified, not absence of pests.
Water & soil context
- Moisture (VWC)
- No universal numerical VWC target established; calibrate to soil, sensor placement and root-zone conditions.
- Salinity tolerance
- No profile-specific salinity rating retained without direct evidence.
- Drought tolerance
- Depends on identity, establishment, climate and soil; do not infer an irrigation threshold from drought tolerance.
Check moisture in the root ball and surrounding soil; avoid persistent saturation. Adjust irrigation to measured site conditions rather than a fixed percentage.
Source: Water Management and Pest Problems — UC IPM ↗ — General woody-landscape guidance, not a species-specific irrigation prescription: both deficit and excess moisture injure roots; new root balls can dry between irrigations. No universal VWC target.
Problems to watch
No species-specific list verified in the cited references. This does not mean absence of pests or stress; investigate changes with a qualified specialist.
Stress signs
