A mature mango tree in USDA Zone 10b (like southern California) typically requires **9–12 gallons of water per week** per inch of trunk diameter during the growing season. Here's how you can fine-tune this estimate:
---
### **Factors to Consider:**
1. **Tree Size**:
- Mature mango trees with a 12-inch trunk diameter may require around **100–120 gallons per week.**
- Measure trunk diameter at chest height to estimate.
2. **Season and Weather**:
- **Growing season (spring/summer):** Mango trees need more water, especially during flowering, fruit set, and fruit development.
- **Dormant season (fall/winter):** Watering can be reduced significantly, as mango trees are drought-tolerant.
3. **Soil Type**:
- Southern California soils can range from sandy to clay.
- Sandy soil requires more frequent watering due to poor water retention, while clay soil retains water longer.
4. **Irrigation Method**:
- Use deep watering to encourage strong root growth.
- Drip irrigation is ideal, providing consistent moisture without overwatering.
5. **Mulching**:
- Apply mulch around the base (but not against the trunk) to retain soil moisture and reduce watering needs.

### **Weekly Watering Example**:
- For a **12-inch trunk diameter tree** during the active growing season:
\[
\text{Gallons per week} = \text{trunk diameter (in inches)} \times 10
\]
\[
\text{Gallons per week} = 12 \times 10 = 120 \, \text{gallons}
\]
Adjust for seasonal needs:
- Growing season: 100–120 gallons/week
- Dormant season: 20–40 gallons/week (or less, depending on rainfall).

### **Zone 10b Adaptations**:
- **Evapotranspiration (ET):** High in hot, dry climates, requiring closer monitoring.
- **Rainfall:** Zone 10b often has minimal rainfall. If rain occurs, reduce watering accordingly.
- **Drought Conditions:** Mango trees tolerate some drought but avoid prolonged dry periods.
