What is a microclimate? Take a look at the photo above.
Just a few feet from a healthy green lawn, there is an area of dead or struggling grass sitting next to a deck and landscape bed. At first glance, it feels confusing. The same sprinkler waters both areas. The same lawn care program was applied to both sections. The grass is only separated by a few feet.
So why does one area thrive while the other struggles? The answer is something called a microclimate.
A microclimate is a small area where growing conditions are different from the surrounding space. In lawns, even subtle differences in sunlight, temperature, airflow, moisture and soil conditions can completely change how grass grows.
What Changed in This Area?
The lawn next to the deck is living in a very different environment than the grass farther out in the open sun.
That shaded section likely experiences:
• Fewer hours of direct sunlight each day
• Cooler soil temperatures in spring
• Reduced airflow
• More moisture lingering overnight
• Different drying patterns after rain or irrigation
Meanwhile, the lawn just a few feet away receives full sunlight, more airflow and more consistent growing conditions. Even though it looks like one lawn to us, the grass experiences two completely different environments.
Microclimates – Small Environmental Differences Create Big Lawn Differences
This is one of the most important concepts homeowners often do not realize about lawns. Grass is extremely responsive to its environment.
Buildings, decks, fences, trees, landscape beds and even neighboring homes all influence:
• Sun exposure
• Heat retention
• Wind movement
• Moisture levels
• Soil temperature
• Root competition
When you combine those differences, some areas simply become much harder places for grass to grow.
“Why Does My Neighbor’s Lawn Look Better Than Mine?”
This is one of the most common questions we hear. Sometimes it is the treatments applied, mowing practices, or watering practices. Honestly, many times the answer has less to do with products/maintenance and more to do with environment.
Your neighbor may simply have:
• More sunlight
• Fewer mature trees
• Better airflow
• Less competition from roots
• Different drainage
• Less reflected heat from structures or pavement
Two lawns on the same street can have completely different growing conditions.
The Goal Is to Work With the Microclimates
The important takeaway is this:
Struggling grass does not always mean you are doing something wrong. Sometimes the environment itself is limiting how successful the lawn can be.
The good news is there are ways to improve these microclimates and help grass perform better:
• Pruning trees to increase sunlight
• Using shade tolerant grass seed blends
• Raising mowing height
• Improving watering practices
• Building soil health
• Reducing stress on shaded areas
At bioLawn, we look beyond just fertilizer and weed control. Understanding how different parts of a property grow is a huge part of creating a healthier lawn.
Because sometimes the difference between a struggling lawn and a thriving lawn is only a few feet.
