- Water deeply 2-3 times weekly during dry season
- Reduce watering to once weekly during wet season (June-October)
- Position soaker hoses 6 inches from plant bases
- Monitor soil moisture using a moisture meter
- Group plants with similar water needs together
- Create watering zones based on sun exposure
| Season | Watering Frequency | Amount per Session |
|---|---|---|
| Dry (Nov-May) | 2-3 times weekly | 1-1.5 inches |
| Wet (Jun-Oct) | 1 time weekly | 0.5-1 inch |
