Overwatering vs. Underwatering: What Your Landscape Is Trying to Tell You

When a lawn starts turning brown or a plant begins to struggle, the first reaction for many homeowners is to reach for the hose.

But before adding more water, it's important to ask a simple question:

Is the problem too little water—or too much?

While underwatering is a common concern during the summer months, overwatering can create just as many problems. In fact, many signs of overwatering and underwatering can look surprisingly similar at first glance.

Learning to recognize these signs can help you make better decisions and keep your landscape healthier throughout the season.

More Water Isn't Always Better

Water is essential for healthy turf, trees, shrubs, and flower beds. However, plants also need oxygen around their roots.

When soil remains saturated for long periods, air spaces in the soil fill with water. This can stress roots, limit nutrient uptake, and create conditions that encourage disease.

Just as plants can suffer from drought stress, they can also suffer from excess moisture.

Signs Your Lawn May Be Overwatered

An overwatered lawn often appears unhealthy despite receiving plenty of moisture.

Common signs include:

Soft or spongy ground
Yellowing grass
Excessive thatch buildup
Mushrooms or fungal growth
Increased disease activity
Weak root development

If water is consistently available at the surface, roots may not develop deeply, leaving the lawn more vulnerable to future stress.

Signs Your Lawn May Need Water

Underwatered turf often displays very different symptoms.

Watch for:

Grass blades that curl or fold
A dull blue-green colour
Lingering footprints after walking across the lawn
Dry, thinning, or brown patches
Slow recovery after hot weather

These signs are often the lawn's way of conserving moisture during periods of stress.

Trees and Shrubs Communicate Differently

Unlike turf, trees and shrubs often show stress through their leaves.

You may notice:

Wilting foliage
Drooping branches
Premature leaf drop
Leaf scorch along the edges
Reduced growth

While these symptoms can indicate drought stress, they can also appear when roots are struggling in overly wet soil.

This is why checking soil moisture is often more reliable than judging by appearance alone.

Before You Water, Check the Soil

One of the simplest ways to determine whether watering is needed is to check the soil.

Dig down a few inches or use a soil probe to see how much moisture is actually present beneath the surface.

The top layer may appear dry while deeper soil remains adequately moist. Likewise, a lawn may appear stressed even when excess moisture is present around the roots.

Taking a few moments to check can prevent unnecessary watering and help avoid long-term issues.

Finding the Right Balance

Every property is different.

Sun exposure, soil type, slope, drainage, and weather conditions all influence how much water your landscape requires.

Rather than watering on a strict schedule, it's often better to observe your lawn and plants, monitor rainfall, and adjust as conditions change.

Listen to What Your Landscape Is Telling You

Healthy landscapes are often the result of small adjustments made over time.

By learning to recognize the signs of overwatering and underwatering, homeowners can make informed decisions that support stronger roots, healthier growth, and better resilience throughout the summer season.
