Key Steps to Train Your Lawn for Water Efficiency:
- Audit your current watering habits and reduce overwatering
- Water deeply but infrequently (1–2 sessions per week)
- Encourage deeper root growth through proper irrigation timing
- Follow local water restrictions and skip unnecessary watering
- Allow your lawn to enter dormancy during extreme heat
With water restrictions becoming more common and concerns about water conservation growing, finding ways to maintain beautiful lawns with less water is more important than ever.
What does "train your lawn to use less water" mean?
Training your lawn for heat and drought requires two significant changes:
- Less supplemental watering
- A shift in perspective
Gradually reducing watering as temperatures increase helps lawns develop resilience. This conditioning enables your lawn to withstand summer heat and recover from heat stress - much like how athletes train to perform better under challenging conditions.
While conditioning your lawn for heat and drought is relatively simple in practice, it can be quite challenging to embrace. With less supplemental water, your grass may not stay picture-perfect green year-round. This is why training your lawn requires a shift in perspective about what a healthy lawn looks like during the peak heat of summer months. A slightly golden lawn in August isn't failing - it's adapting to more natural growth patterns!
Key Terms:
- Dormancy: A natural protective state where grass turns brown or yellow to conserve energy and survive drought, extreme heat or other stressors.
- Deep watering: Irrigating long enough for water to penetrate 6–8 inches into the soil, encouraging roots to grow downward.
- Infrequent watering: Allowing enough time between each watering session for the upper layers of the soil to dry. This teaches the grass to rely on deeper soil moisture.
- Drought stress: Signs that grass lacks sufficient water, including wilting, footprinting (grass stays flat when stepped on), and color changes from green to bluish-gray.
How to train your lawn to use less water
How much water does my lawn need per week?
Auditing your irrigation system or checking how much water you're currently using is the essential first step to cutting back. Many homeowners unknowingly overwater their lawns.
Watering Guidelines:
- Weekly water target: 1–2.0 inches (including rainfall)
- Watering sessions: 1–4 deep sessions per week
- Best time to water: Before 10 AM
- Target soil moisture depth: 6–8 inches
How do I know if my lawn needs water?
Once you understand your watering patterns, skip unnecessary irrigation. If it has rained recently or your lawn still looks healthy with good moisture, skip supplemental watering completely. If your region gets adequate rain through the summer, you may not need to water at all.
Signs your lawn needs water:
- Grass blades wilt or curl
- Footprints remain visible after walking on the lawn
- Color shifts from green to bluish-gray
Consider installing a simple rain gauge or smart irrigation system that automatically adjusts to weather conditions. Even manually checking the forecast and turning off scheduled watering before rain can help save hundreds of gallons each month.
Sunday Tip:
Shady lawn areas need about 30% less water than sunny areas—adjust irrigation zones accordingly rather than watering everything equally.
How does deep watering help grass roots grow deeper?
Deep and infrequent watering encourages roots to grow downward in search of moisture, creating naturally drought-resistant lawns. Shallow, frequent watering keeps roots in the top 1–2 inches of soil where moisture evaporates fastest, making grass more vulnerable to heat and drought.
This deep watering method, or applying water less often but for longer periods, helps moisture penetrate deeper into the soil. The result? Grass roots grow deeper accessing deep soil moisture, and become significantly more resilient to heat and summer stress.
Follow water restrictions
Check with your local municipality to make sure that you're in compliance with your allotted watering days and times. Besides avoiding potential fines, following these restrictions helps your community conserve water during critical periods.
Being a good water steward creates that feel-good summer vibe while keeping your lawn alive.
Can I let my lawn go dormant during drought?
During peak heat periods, shift your goal to "survive, not thrive". This means watering just enough to keep your lawn alive and allowing a yellow lawn during the hottest weeks.
You can typically maintain a lawn by applying just 1/10 to 1/4 of an inch of water every three weeks during extreme heat stress. This minimal watering prevents the loss of established grass completely while still conserving water.
Sunday Tip:
If your lawn enters dormancy (turns brown or yellow), don't panic and start overwatering. Dormancy is a natural protective state that helps grass survive extreme conditions. Forcing grass out of dormancy with heavy watering actually stresses the plants more. Let nature do its thing, and your grass will bounce back faster when conditions allow for active growth.
How to use less water on lawns with Sunday
With increasingly warmer temperatures and prolonged drought conditions across many regions, we need to reevaluate the role and use of water within our lawn care routines.
Simply put, we are committed to conserving water in yards. By training lawns to survive on less water and adjusting our expectations for just three or four months of the year, we can do a whole lot of good for the planet while preserving our lawns for generations to come.
Sunday products are specifically formulated to optimize water usage in our backyards—here's how:
Seaweed extract
Many of our lawn nutrients contain powerful seaweed extract that naturally supports heat tolerance at the cellular level. Research published in the National Library of Medicine shows that seaweed extracts enhance turfgrass performance during prolonged irrigation intervals. This sustainably-sourced ingredient also reduces the need to water by helping your soil stay saturated for longer, meaning each watering session delivers more benefit to your lawn.
Sunday Tip:
Tip: Sunday's Lawn Aid formula contains seaweed extract that works with your soil's natural biology to support heat resistance.
Drought prevention
Sunday's Drought Defense is a liquid lawn treatment that enhances your lawn's drought resilience. Using advanced surfactant technology with seaweed and potassium, it supports water retention and distribution in soil. This helps save up to 20% on water usage during dry periods.
Drought Defense Lawn Treatment
- Enhances drought resiliency
- Saves up to 20% of water use
- Ideal for drought-prone areas
- Made for any grass type
- Zero pesticides
Drought tolerant grass seed
Many of the Sunday grass seeds are A-List approved. A-List Approval is a rigorous process to test grass cultivars for their ability to thrive with lower levels of fertilizer, water, and pesticides once established.
Additionally, Sunday seeds are lightly coated with a moisture retaining coating, which helps new seedlings establish more easily (especially if you miss a watering after planting!). This gives you better results with less stress and water waste.
Frequently Asked Questions
How often should I water my lawn to save water? Water 1–4 times per week, depending on temperature, with deep sessions rather than daily light watering. Aim for 1 – 2.0 inches total per week, including rainfall.
What are the signs my lawn needs water? Look for wilting grass blades, footprints that stay visible after walking, and a color shift from green to bluish-gray.
Can I let my lawn go dormant during drought? Yes. Dormancy is a natural survival mechanism. Water minimally (1/10 to 1/4 inch every three weeks) to keep roots and crowns alive, and your lawn will recover when conditions improve.
How deep should I water my lawn? Water should penetrate 6–8 inches into the soil to encourage deep root growth and drought resilience. Typically applying ½ an inch of water will accomplish this goal.
Key Takeaways
- Train your lawn gradually by reducing watering frequency over time to encourage deeper root growth and natural drought resilience.
- Water deeply but infrequently—aim for 1–2 inches per week in 1–4 sessions, watering before 10 AM. If the temperatures are cool, wait to water until you start to see signs of wilt.
- Learn to read your lawn's signals: wilting, footprinting, and color changes indicate when watering is truly needed.
- Allow dormancy during extreme heat—a golden lawn is surviving, not dying, and will recover when temperatures drop.
- Adjust expectations: a slightly golden lawn in summer is a sign of adaptation, not failure.
