Getting the Greenest Lawn: The Role of Fertilizers

Homeowners in the Northwest suburbs take pride in their lawns, and there’s nothing quite like the sight of a lush, green carpet of grass enhancing a property’s curb appeal. Achieving this healthy lawn isn’t just a matter of luck; it’s also about understanding the role of lawn fertilizers.

If you want a lawn that’s the envy of the neighborhood, this guide is for you.

Our Lawn Fertilization Program

Lawn Fertilization: Timing is Everything.

Our area experiences a continental climate with cold winters and warm summers. The best times to fertilize lawns in this region are aligned with the growth cycles of cool-season grasses, which are most common in the Midwest.

Early Spring Fertilizer

(April to Early May)

After the frost has passed and your grass starts to wake up from its winter slumber, it needs a nutrient boost to jump-start its growth. A fertilizer rich in nitrogen can help achieve a rapid green-up.  Pre-emergent herbicides for the prevention of crabgrass are made at this time as well.


Early Summer Fertilizer

(June to Early July)

As temperatures begin to rise, lawns can benefit from a balanced fertilizer that continues to promote green growth but also strengthens the grass against the approaching heat.


Summer Soil Builder

(Mid-July - August)

The application of high carbon, organic-based nutrient sources helps enrich the soil and provide a stable source of slowly available nutrients to help maintain turf health and vigor through the summer months.


Fall Fertilizer

(October - November)

After the heat of summer, your lawn is ready for recovery. Fertilizing in the fall helps the grass repair any damage and prepare for the winter ahead. Lawn fertilizers with higher amounts of potassium are used to enhance rooting and improve resistance to cold.

Types of Lawn Fertilizers We Use:

Controlled-Release Fertilizer

Encapsulated by an advanced polymer coating (and sometimes sulfur) that allows water to readily enter and dissolve the mineral nutrients inside but regulates the diffusion of those nutrients out of the coating. This effectively allows for a predictable release of nutrients over a prescribed amount of time. This improves nutrient availability and take up, and it greatly reduces the chance of nutrient leaching or run-off.

Slow-Release Fertilizer

Releases nutrients gradually with time and can be an inorganic or organic form. It relies on microbial activity in the soil to convert the nutrients to a plant available form which reduces the chance for leaching or run-off and ensures plant availability over a longer period of time. Increased soil moisture and soil temperature leads to more microbial activity, which in turn leads to a higher release rate.

Stabilized Nitrogen Fertilizer

Urea nitrogen that is coated with inhibitors that delay the conversion of urea to ammonium. This greatly reduces nutrient losses from volatilization (gassing-off into the atmosphere), denitrification, and leaching. The result is a stable form of nitrogen that provides anywhere from 8-12 weeks of feeding.

Organic-Based Fertilizer

A combination of an organic nutrient source, such as composted poultry manure, bone meal, blood meal and/or reclaimed natural nutrient sources, and a controlled-release synthetic fertilizer. The synthetic fertilizer is formulated to release over a shorter amount of time for quicker response, while the organic source will provide extended feeding.

Organic Fertilizer

OMRI certified fertilizer derived from meat and bone meal, blood meal, composted poultry manure and other natural sources. Organic fertilizers provide a stable, slowly available source of nutrients that is available as the turf needs it. Because they are insoluble and depend on microbial activity to convert them to plant usable forms, plant response will be slow, but there is little risk of waste from leaching or run-off.

Science-Based Lawn Fertilization

We have been helping our customers create beautiful lawns for over 20 years.

The key to our success is simple. We use a science-based approach to lawn care.

We understand Best Management Practices (BMPs) for our local communities and consider their prevailing turf species, soil types, and growing conditions.

We know that the needs of your lawn and its ability to take up nutrients changes throughout the growing season. With this in mind, we select and apply fertilizer products that are most appropriate based on your turf type, growing conditions, and time of year to ensure your lawn looks its best.

Decades of turf research have proven granular fertilizers to be superior to liquid fertilizers in turf fertility programs. They provide the necessary nutrient levels needed to sustain a thick, healthy lawn. You can be assured that we only use granular fertilizers in our lawn care programs.
