If your lawn looks dull or patchy despite watering and fertilizing, the problem may lie beneath the surface. Lime lawn care is one of the most effective ways to restore soil health and bring your grass back to life. By balancing soil pH, lime helps your lawn absorb nutrients more effectively, leading to greener, stronger turf.
At Mile High Lifescape, we’ve spent nearly 20 years helping Denver homeowners build vibrant lawns from the ground up. Here’s what you need to know about applying lime—when to do it, how it works, and how to tell if your lawn needs it.
What Is Lime and Why Does Your Lawn Need It?
Lime is a soil amendment made from ground limestone, used to reduce soil acidity. There are two main types:
-
Calcitic lime: High in calcium, commonly used in Denver where magnesium levels are usually adequate.
-
Dolomitic lime: Contains both calcium and magnesium, ideal for soils deficient in both.
When your soil is too acidic, grass can’t absorb key nutrients—even if you’re fertilizing regularly. Lime raises the pH, making nutrients more available, improving root health, and creating a better environment for beneficial microbes.
How Soil pH Affects Lawn Health
Most grass types thrive in slightly acidic to neutral soil—between 5.8 and 7.0 pH. When pH drops too low, your lawn starts showing signs like yellowing, weak growth, and poor response to fertilizers.
While many areas in Denver naturally have alkaline soil, factors like pine trees, heavy irrigation, and rainfall can cause local acidity. That’s why testing is key.
Key Benefits of Lime Lawn Care
-
Improves nutrient uptake
-
Strengthens root systems and drought resistance
-
Reduces moss and acid-loving weeds
-
Supports beneficial microbial activity
-
Boosts the effectiveness of fertilizers
By correcting the pH, you help your lawn work more efficiently and grow more vigorously year-round.
Signs Your Lawn Might Need Lime
Watch for these indicators:
-
Grass stays yellow despite proper care
-
Moss keeps returning
-
Weeds like clover, dandelion, or chickweed are taking over
-
Fertilizer has little effect
-
Soil test shows a pH below 6.0
A simple soil test will confirm if lime is necessary. Home kits offer quick insight, but professional testing is best for precise results.
Choosing the Right Lime Product
For most Denver lawns, pelletized calcitic lime is the best option. It’s easy to spread, low on dust, and safe for residential use. Powdered lime acts faster but is harder to handle. Liquid lime is useful for spot treatments but doesn’t last as long. Hydrated lime is fast but too strong for DIY—leave that to the pros.
Best Time to Apply Lime
-
Fall (September–November): Ideal time for lime to work through winter and prep your lawn for spring.
-
Early spring (February–April): A great second option if fall was missed.
-
Avoid summer applications, and never apply when the ground is frozen or saturated.
Soil should be slightly moist—not dry, not soaked—for the lime to start working effectively.
How to Apply Lime Properly
-
Test your soil to determine how much lime is needed.
-
Mow and clean up the lawn to ensure good soil contact.
-
Aerate if the soil is compacted.
-
Spread evenly using a broadcast or drop spreader.
-
Water lightly after application to activate the lime.
-
Wait at least two weeks before applying fertilizer.
For large areas or heavily acidic soil, consider a split application in fall and spring for safer, steady results.
Safety Reminders
-
Wear gloves, eye protection, and a mask when handling lime
-
Keep children and pets off the lawn until after the first watering
-
Don’t apply before heavy rain
-
Store lime in a dry, sealed container
Maintain and Monitor
Lime application isn’t a one-time fix. Test your soil every 1–2 years and reapply lime only when needed. Keep an eye out for yellowing grass or moss as signs the pH may be dropping again.
Also, document each application—product used, date, and amount—to track how your soil is responding.
