How to water your SD lawn the right way
Deep, infrequent watering builds deep roots. Light daily watering does the opposite. Here's the right cadence for San Diego.
What you'll learn
- Why deep and infrequent watering beats daily light watering every time
- How to calculate your runtime (measure output with a tuna can)
- Best time of day to water (4-8 a.m. in SD)
- How to tell over-watering vs. under-watering from the lawn itself
Step by step
- Place an empty tuna can or straight-sided container on the lawn mid-zone.
- Run that zone for 15 minutes.
- Measure water depth in the can. Multiply by 4 to get the per-hour rate.
- Calculate total runtime needed: 1 inch of water per week in summer (less in winter).
- Split the weekly need across 2-3 deep sessions, not daily light runs.
Safety note
If your lawn dries out between waterings in under 3 days, either the zone is under-watered or the root system is too shallow. Both are fixable.
