How to Protect Your Lawn and Landscape During Hot, Dry Summer Weather

Hot, dry summer weather can be tough on Minnesota lawns and landscapes. A stretch of high temperatures combined with little rainfall can quickly turn a healthy, green property into a stressed landscape.

For homeowners, the key is understanding what causes heat and drought stress, how plants respond, and how to use water efficiently when moisture is limited.

At Fas-cut, we help homeowners and businesses throughout the Twin Cities and surrounding communities maintain healthy lawns and landscapes through every season. Here are some practical ways to help your property make it through the hottest and driest parts of summer.

What Causes Summer Stress on Your Lawn?

Grass and landscaping are affected by more than just a lack of rain. Several conditions can compound stress during hot weather:

• Extended periods of high temperatures increase water loss through evaporation and plant transpiration.
• Dry soil means roots have less moisture available to absorb.
• Hot, dry winds can pull moisture from plants and soil even faster.
• Full-sun areas typically dry out faster than shaded portions of the landscape.
• Compacted soil can prevent water from reaching the root zone effectively.
• Heavy foot traffic can damage already-stressed grass.
• Short mowing heights leave less leaf surface to protect the plant and soil from heat.
• Newly seeded or newly sodded lawns are particularly vulnerable because their root systems are not yet well established.

The combination of heat and drought can be especially challenging for Minnesota’s cool-season grasses. During prolonged summer heat, these grasses may naturally slow their growth or enter dormancy.

Don’t Panic When Your Grass Turns Brown

A brown lawn isn’t necessarily a dead lawn.

Cool-season turfgrass has a natural survival mechanism that allows it to enter summer dormancy when temperatures are high and water is scarce. The grass stops actively growing and conserves its available resources, resulting in a brown or straw-colored appearance.

In many cases, healthy, established grass can remain dormant for an extended period and recover when cooler temperatures and adequate moisture return. We recommend maintaining some moisture around dormant turfgrass crowns and roots during prolonged drought to improve its chances of survival.

That means you don’t necessarily have to keep your lawn bright green throughout a drought.

Dormant vs. Dead: What’s the Difference?

The important question is how long the grass has been under severe stress and whether the plant’s crown and roots remain alive.

Dormant grass may look completely brown but can begin producing new green growth when adequate moisture returns. Dead grass, on the other hand, will not recover because the plant has suffered damage beyond what it can survive.

There isn’t a single number of days that determines when grass dies. Turf survival depends on the grass species, age of the lawn, soil conditions, rooting depth, temperature, shade, traffic and severity of the drought.

For example, research and field observations have demonstrated that some established tall fescue can survive surprisingly long periods of summer drought and recover from the crown after water returns.

New lawns deserve special attention. Grass established from recent seed or sod has a smaller root system and generally should not be allowed to go dormant. Regular watering is much more important during the establishment period.

Water Deeply Rather Than Watering Constantly

If your goal is to keep your lawn green and actively growing, the most efficient approach is generally deep, thorough watering rather than frequent, shallow watering.

A commonly used guideline for established cool-season turf is approximately 1 inch of water per week from rainfall and irrigation combined, although actual needs vary with weather, soil and grass type.

Deep watering encourages moisture to reach the root zone instead of keeping only the surface wet. Frequent, light watering can encourage shallower roots and leave grass more vulnerable when the soil dries out.

If your soil cannot absorb a full inch at once without runoff, divide the irrigation into multiple applications.

Water in the Morning

Early morning is generally the most efficient time to water.

Cooler temperatures and lower evaporation rates allow more water to reach the soil instead of being lost to the atmosphere. Morning irrigation also gives grass blades time to dry during the day, which can help reduce conditions favorable to certain turf diseases.

Watering during the hottest part of the afternoon may provide temporary relief, but it is typically less efficient because more water is lost to evaporation.

How to Make Your Watering More Economical

Watering doesn’t have to mean running your sprinklers for hours every day. A few simple adjustments can significantly improve efficiency.

1. Measure Before You Adjust

Don’t assume your sprinkler system is applying the amount of water you think it is.

Place several small, straight-sided containers around the lawn and run your irrigation system. Measuring the water collected in different areas can reveal whether your system is applying water evenly or leaving dry spots.

This is particularly important with older irrigation systems, where sprinkler heads may have become clogged, damaged or misaligned. Extension specialists recommend periodically checking irrigation systems for uniform coverage.

2. Fix Overspray and Runoff

Water landing on sidewalks, driveways and patios isn’t helping your landscape.

Adjust sprinkler heads so water stays within the lawn or planting bed. If water begins running down the street or pooling in one area, the soil may not be able to absorb water as quickly as it is being applied.

Shorter irrigation cycles with a break between them can allow water to soak into the soil rather than run off.

3. Use Irrigation Controls Wisely

Automatic irrigation can make watering much easier, but automation doesn’t necessarily mean efficiency.

During hot weather, periodically check your irrigation schedule and adjust it based on rainfall and actual landscape conditions. A properly designed and maintained irrigation system can deliver water where it is needed while reducing the waste associated with manual watering.

Fas-cut provides irrigation and sprinkler system services designed to make maintaining a healthy lawn and landscape easier.

4. Prioritize What Needs Water Most

If water is limited, prioritize.

Newly planted trees, shrubs, flowers and recently established lawns generally need more attention than mature, established landscape plants with extensive root systems.

Rather than trying to keep every square foot of turf perfectly green during a drought, focus your available water on plants and areas where moisture will make the biggest difference.

Don’t Forget Your Trees and Landscape Plants

Grass often gets the most attention, but trees and shrubs can suffer significant stress during extended periods of heat and drought.

Watch for signs such as:

• Wilting or curling leaves
• Premature leaf drop
• Brown or scorched leaf edges
• Drooping branches
• Dry soil around the root zone
• Newly planted trees or shrubs showing rapid signs of stress

New plantings deserve particular attention because their roots have not yet expanded into a large area of surrounding soil.

A good layer of mulch around trees and planting beds can also help conserve soil moisture and moderate soil temperatures. Keep mulch several inches away from tree trunks rather than piling it directly against the bark.

Give Your Lawn a Break During Extreme Heat

When grass is severely stressed, mowing and traffic can create additional damage.

Consider raising the mower height during periods of summer stress. Taller grass provides more leaf surface for photosynthesis and helps shade the soil, reducing moisture loss.

Avoid mowing dormant or severely drought-stressed turf more than necessary. Heavy foot traffic and vehicle traffic can also damage turf crowns when the grass is already struggling.

And resist the temptation to push growth with fertilizer during extreme heat and drought. Stressed turf is not in an ideal condition to make use of additional nutrients.

Sometimes the Most Economical Choice Is Letting the Lawn Go Dormant

Maintaining a perfectly green lawn through a prolonged drought can require a significant amount of water.

For an established lawn, allowing cool-season turf to enter summer dormancy can be a reasonable strategy when water is limited. The objective changes from keeping the grass green to keeping the grass alive.

Those are two very different watering goals.

If maintaining a green lawn is your priority, consistent irrigation is necessary. If conserving water is the priority, allowing established turf to go dormant while providing occasional moisture to help protect the plant’s crown and roots can be a more economical approach.

The key is consistency. Bringing a dormant lawn out of dormancy and then allowing it to dry out again can place additional stress on the turf.

When to Call a Professional

If you’re unsure whether your lawn is dormant, damaged or dead—or you’re seeing inconsistent watering throughout your property—it may be time to have the landscape evaluated.

We can identify problems such as:

• Uneven sprinkler coverage
• Broken or clogged sprinkler heads
• Poorly positioned heads
• Runoff and drainage problems
• Inefficient irrigation schedules
• Areas receiving too much or too little water

Keep Your Landscape Healthy Through the Heat

Hot, dry weather doesn’t automatically mean your lawn or landscape is headed for disaster. Understanding how plants respond to heat and drought—and adjusting your maintenance practices accordingly—can make a major difference.

Water smarter, not simply more. Water deeply when appropriate, irrigate during efficient times of day, monitor your sprinkler coverage, protect new plantings, raise your mowing height and recognize that a brown lawn may be dormant rather than dead.

And when summer conditions become too much for your landscape to handle on its own, Fas-cut is here to help.
