Key Takeaways
Lawn care myths debunked:- Deep, infrequent watering is best: Watering 2-3 times per week encourages strong root growth and drought resistance.
- Mowing too short weakens grass: Keeping grass at 3-4 inches protects roots, retains moisture, and prevents weed invasion.
- Grass clippings nourish the lawn: Leaving clippings to decompose naturally provides essential nutrients and reduces fertilizer dependence.
- Fall fertilization strengthens roots: Applying fertilizer in late summer or fall enhances lawn resilience for winter survival.
Maintaining a lush, green lawn is every homeowner’s dream, but misinformation often leads people down the wrong path. There are countless lawn care myths that have been passed down for generations, causing more harm than good.
At Cory’s Lawn Service, we believe in helping Reno and Sparks homeowners separate fact from fiction, ensuring their yards thrive year-round. Let’s set the record straight by debunking the most common lawn care myths with scientifically backed information.
Myth #1: Watering Your Lawn Every Day Is Essential
Many homeowners believe that watering the lawn daily keeps it healthy. However, frequent shallow watering can weaken grassroots, making them more vulnerable to drought and disease.
The Truth:
Lawns benefit more from deep, infrequent watering. Instead of daily watering, aim for 1 to 1.5 inches per week, including rainfall. This encourages deep root growth, which helps grass withstand dry conditions.
Best Practice:
Water your lawn 2-3 times per week in the early morning.
Use a soaker hose or irrigation system to distribute water evenly.
Conduct a "screwdriver test"—if a screwdriver easily penetrates the soil 6 inches deep, the lawn has received enough water.
Myth #2: Cutting Your Grass Short Reduces Mowing Frequency
It might seem logical that mowing your grass as short as possible means you won’t have to mow as often. Unfortunately, this practice can lead to a scorched and unhealthy lawn.
The Truth:
Scalping your lawn stresses the grass, weakens its root system, and invites weeds to take over. Taller grass shades the soil, retains moisture, and supports stronger roots.
Best Practice:
Set your mower blade to 3–4 inches for optimal lawn health.
Never remove more than ⅓ of the grass height in a single mowing.
Alternate mowing directions to prevent soil compaction.
Myth #3: Grass Clippings Need to Be Bagged and Removed
Many believe that leaving grass clippings on the lawn causes thatch buildup, making the yard look messy and unhealthy.
The Truth:
Grass clippings are beneficial for your lawn! They decompose quickly, returning essential nutrients like nitrogen back into the soil. This natural fertilization helps reduce the need for synthetic fertilizers.
Best Practice:
Use a mulching mower to break down clippings efficiently.
Only bag clippings if they are excessively long or wet.
Avoid piling up clippings in one area to prevent smothering the grass.
Myth #4: Spring Is the Best Time to Fertilize
It’s common to think that fertilizing in early spring kickstarts lawn growth. While some fertilization is beneficial, overdoing it too early can lead to weak roots and excessive blade growth.
The Truth:
The best time to fertilize depends on your grass type. Cool-season grasses (like those common in Reno and Sparks) benefit most from fall fertilization, which strengthens roots for winter survival.
Best Practice:
Apply a balanced fertilizer in late summer or early fall.
Use a slow-release nitrogen fertilizer for steady growth.
Test your soil to determine the exact nutrient needs before fertilizing.
Myth #5: More Fertilizer Equals a Healthier Lawn
It’s tempting to think that more must be better if some fertilizer is good. However, over-fertilizing can lead to excessive growth, weak roots, and even chemical burns.
The Truth:
Too much fertilizer encourages rapid, weak growth, making the lawn susceptible to disease and pests. Excess nitrogen runoff also harms the environment, affecting local waterways.
Best Practice:
Follow manufacturer recommendations on fertilizer application.
Apply fertilizers at the right time—fall for cool-season grasses, spring for warm-season grasses.
Use organic or slow-release fertilizers for steady nutrient absorption.
Myth #6: Dandelions and Weeds Mean Your Lawn Is Unhealthy
Seeing dandelions or clover in your yard might make you think your lawn is failing, but that’s not necessarily true.
The Truth:
Certain weeds, like clover, improve soil health by naturally fixing nitrogen. While an abundance of weeds can signal lawn stress, occasional weeds do not indicate poor lawn care. Read this article for more information of the benefit of dandelions.
Best Practice:
Improve lawn density through proper mowing, watering, and fertilization.
Apply pre-emergent herbicides in early spring to prevent weed growth.
Spot-treat problem areas instead of applying chemicals across the entire lawn.
Myth #7: You Should Rake All Your Leaves in Fall
Most homeowners spend hours raking leaves in the fall, believing a leaf-free lawn is healthier.
The Truth:
Leaves act as natural mulch, helping to retain moisture and insulate the soil. However, thick layers can smother grass, so proper leaf management is key.
Best Practice:
Mulch leaves using a mower instead of bagging them.
If leaf cover is excessive, rake and compost them for garden use.
Leave a thin layer of mulched leaves to enrich the soil naturally.
