Missteps with lawn irrigation are common reasons why many homeowners find their yards covered in dead spots. Watering too often leaves little room for oxygen to move through the soil, causing grass roots to suffocate. On the other hand, when the turf is not watered enough, it can develop dry patches. Waxy membranes form on soil particles that repel moisture, which means lawn irrigation won’t restore the vegetation. To prevent these problems, below are signs you could be under- or over-watering the grass. 

How to Tell If You Need to Adjust Your Lawn Irrigation Efforts

1. Thatch Buildup

Resembling hay, thatch is the debris that rests on top of turf. A mixture of roots, stolons, and decaying plant matter, thatch gets denser and more difficult to remove when grass is watered too often.

When there’s excess moisture, organisms can no longer accelerate the decomposition process. The thick covering impedes oxygen flow, compromising the development of new roots and causing mature roots to suffocate. 

2. Fungus Development

Overzealous lawn irrigation can lead to fungus growth. Fungi spores need moisture to reproduce, making a saturated lawn the perfect environment for rapid development.

Mushrooms are one fungus that can sprout in soggy conditions. Slime mold can also form on damp grass. The gooey membrane covers the ground, preventing sunlight and oxygen from seeping into the soil. 

3. Slow Growth

Make a note of any changes in the grass growing rate. If there’s not enough water in the soil, the turf will develop slowly. The longer you wait between watering intervals, the greater risk of permanent growing problems.

Observing is the best way to gauge when grass needs hydration. When grass loses more water than roots absorb, you’ll notice the blades are wilted. When thirsty, the vegetation can also take on a blueish tint.
