A homeowner once told me he watered his lawn for 20 minutes every single day. His lawn was brown, his water bill was $180/month. His sprinklers were running at noon in July — 90% of that water evaporated before hitting the roots. I showed him how to measure his actual precipitation rate. We switched to twice a week, early morning cycles. Three weeks later his lawn was green and his bill dropped to $70.
How much water does a lawn actually need per week?
The short answer is 1-1.5 inches per week including rainfall. I have seen this pattern repeat across hundreds of systems I have diagnosed and repaired over the years.
To measure this properly, start by looking at your specific situation. Most residential systems operate within standard parameters, but every property has unique characteristics. I recommend taking measurements rather than guessing. Professional installers typically adjust these factors during the initial assessment.
For example, on a recent job I diagnosed a system that had been struggling for months. The homeowner had been measure all the wrong things. Once I applied the correct approach, the issue resolved in under an hour. This is why understanding these fundamentals matters more than buying expensive equipment.
How often should I water my lawn in summer vs spring?
The short answer is 30-45 minutes per zone for rotary heads. I have seen this pattern repeat across hundreds of systems I have diagnosed and repaired over the years.

What time of day is best for irrigation?
The short answer is best window: 4 AM to 10 AM. I have seen this pattern repeat across hundreds of systems I have diagnosed and repaired over the years.
