Bay Laurel
Bay laurel is a Mediterranean woody perennial adaptable to a broad range of well-drained soils. It can be maintained by pruning for leaf production, but persistent waterlogging and severe frost can cause significant damage.
Profile
- Origin
- Mediterranean Basin
- Growth habit
- Slow-growing evergreen shrub or tree
- Soil pH
- PROSEA reports satisfactory growth across pH 4.5–8.3
- Light
- Full sun to partial shade
- Flowering biology
- Separate male and female plants; female plants produce fruits
Water & soil context
- Moisture (VWC)
- No numeric volumetric water content sensor target is provided by the cited sources.
- Salinity tolerance
- No numeric salinity tolerance threshold is provided by the cited sources.
- Drought tolerance
- A broad climatic rainfall range is documented, but the sources do not provide a transferable drought or irrigation threshold.
Illustrative monitoring-depth band
6–12 in
Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.
Good drainage is essential because waterlogging is not tolerated. Container moisture guidance in the references should not be converted directly into field irrigation targets.
Problems to watch
- Phytophthora root rot
- Colletotrichum leaf spot
- Scale insects and psyllids
Stress signs
- Yellowing and wilting leaves with twig dieback associated with Phytophthora
- Expanding brown leaf spots associated with Colletotrichum
- Aboveground dieback following severe frost
Where you'll find it
- Fresh or dried culinary leaves
- Leaf essential oil
- Hedges and topiary
