Summer is the season when your lawn needs irrigation the most; but it’s also when many homeowners have the most questions. Whether you’re dealing with dry patches, rising water bills, or just unsure of the best schedule, you’re not alone.
In towns like Bedford, Weston, Newton, Winchester, and Wellesley, where the heat can spike and rainfall can be unpredictable, understanding how to manage your irrigation system is key to maintaining a healthy, green lawn.
Here are the 10 most common questions we hear from homeowners each summer; along with expert answers to help you water smarter.
1. How often should I water my lawn in the summer?
Most lawns need about 1 to 1.5 inches of water per week during the summer. That usually means watering 2–3 times per week, depending on your soil type, sun exposure, and rainfall.Deep, infrequent watering is better than daily shallow watering. It encourages deeper roots and improves drought resistance.
2. When is the best time of day to water?
Early morning—between 4 a.m. and 8 a.m.—is ideal. Watering in the morning reduces evaporation and gives grass time to dry before nightfall, which helps prevent fungal diseases.Avoid watering in the heat of the day or at night, when moisture can sit on the grass too long and cause disease.
3. Why does my lawn still have dry spots even though I’m watering?
Dry patches may mean your system is missing certain areas due to:
- Clogged or misaligned sprinkler heads
- Improper zone design
- Water pressure issues
- Thatch buildup or compacted soil
Walking your lawn while the system is running can help you spot problems early. If the dry spots persist, it’s time for a mid-season system check.

4. How long should I run each irrigation zone?
This depends on your system’s output and soil type. As a general rule:
- Spray heads: 10–15 minutes per zone
- Rotary heads: 20–30 minutes per zone
- Drip irrigation: 30–60 minutes for garden beds
The goal is to deliver about ½ inch of water per session. You can measure this by placing a small container (like a tuna can) in the watering area and timing how long it takes to fill.
5. Can I water too much during the summer?
Yes! Overwatering can lead to:
- Shallow root systems
- Lawn fungus and disease
- Runoff and wasted water
- Higher utility bills
If your lawn feels soggy, footprints linger, or mushrooms appear, it’s a sign you’re watering too frequently or for too long.
6. Should I adjust my system during a heatwave?
In extreme heat, your lawn may need slightly more frequent watering. However, it’s important not to overdo it. Instead, focus on:
- Deeper, longer watering to reach the roots
- Watering earlier in the morning to minimize evaporation
- Ensuring even coverage across all zones
Smart controllers, like Hunter’s Hydrawise systems, can automatically adjust watering schedules based on local temperatures and conditions.
7. How do I know if my system is running efficiently?
Look for signs like:
- Even lawn color and growth
- Low water bills relative to lawn size
- No signs of runoff or puddling
- Minimal overspray on sidewalks and driveways
If your system was professionally installed and tuned regularly, you should expect efficient performance. If not, an upgrade or inspection may be needed.
8. Is it worth upgrading to a smart irrigation system in summer?
Absolutely. Summer is when smart irrigation offers the biggest benefits. A Hunter Smart Controller can:
- Monitor local weather and adjust schedules in real time
- Pause watering when rain is forecasted
- Alert you to leaks or overuse
- Let you control everything from your phone
Upgrading in summer means your lawn will immediately benefit—especially during heatwaves or dry spells.

9. What’s the best way to adjust my irrigation system throughout the summer?
We recommend:
- Monitoring your lawn weekly for signs of stress
- Using rain and moisture sensors to prevent overwatering
- Adjusting for weather changes every few weeks
- Scheduling a mid-season tune-up with a local pro
If you have a smart system, make sure firmware is updated and the weather sync is enabled for best performance.
10. How do I prepare for summer restrictions or drought conditions?
Many Massachusetts towns impose watering restrictions during dry spells. A smart system helps you stay compliant by:
- Watering at approved times only
- Reducing frequency without harming the lawn
- Switching to alternate days automatically
Drip irrigation zones and low-flow heads also help conserve water while keeping your landscape healthy.
