When Should You Start Lawn Care in St. Louis? Why March Matters for a Healthy Lawn

The growing season in St. Louis begins long before grass turns bright green. That is why Kickstarter Round lawn treatments begins early in the year. Starting lawn service now prepares turf for the entire season ahead by feeding dormant grass and preventing weeds before they appear.


For homeowners who want a lawn that looks thick, green, and healthy all spring and summer, the first round of treatment is one of the most important.



Why Early Lawn Treatments Matter



Many weeds and lawn problems start developing before you can even see them. Crabgrass, for example, begins germinating when soil temperatures reach about 55 degrees according to research from the University of Minnesota Extension.


Once those weeds are visible, they have already taken root and begun competing with grass for nutrients and water.


Starting lawn treatments early gives your lawn a head start. Instead of reacting to problems later in the season, the strategy focuses on preventing them in the first place.


This is the goal of the Kickstarter Round lawn treatment.



What the Kickstarter Round Lawn Treatment Includes



The first round of lawn service focuses on two key areas: feeding the lawn and preventing weeds.



Fertilizer and Pre-Emergent



A balanced granular slow release fertilizer helps grass wake up gradually as soil temperatures rise. Slow release nutrients provide steady feeding instead of a quick burst that fades quickly.


The treatment also includes a pre-emergent that creates a protective barrier in the soil. This prevents crabgrass seeds from germinating in the first place.


According to Iowa State University Extension, pre emergent herbicides are most effective when applied before crabgrass germination begins.



Stopping weeds before they grow is far easier than removing them later.



Broadleaf Weed Control



Some weeds may already be present in early spring. When needed, broadleaf weed control is applied to target those weeds without harming the surrounding grass.


Common broadleaf weeds include:


  • Dandelions

  • Chickweed

  • Clover

  • Plantain



Controlling these weeds early prevents them from spreading across the lawn.



The Kickstarter Round Is the First Step in a Six Round Lawn Plan



Healthy lawns do not happen with a single treatment. Turf needs different nutrients and protection throughout the year as weather, soil conditions, and growth patterns change.


The Kickstarter Round is the first step in a six round lawn plan designed for St. Louis lawns.



1. Kickstarter Round



This treatment wakes up the lawn after winter. Fertilizer feeds the grass while pre emergent protection blocks crabgrass and early weeds.



2. Weed Suppression Round



Spring weeds begin emerging as temperatures rise. This round focuses on controlling new weed growth before it spreads.



3. Root Builder Round



Early summer treatments support deeper root development. Strong roots help grass survive heat, drought, and heavy use.



4. Grub Reduction Round



Grubs feed on grass roots and can destroy large areas of turf. Preventive treatments help stop grub damage before it begins.


According to the University of Missouri Extension, grubs feeding on roots can cause lawns to thin or die in patches.

5. Soil Health Round



Healthy soil is the foundation of a healthy lawn. This treatment supports microbial activity and improves nutrient availability.



6. Cold Prep Round



The final treatment prepares grass for winter dormancy. Strong roots and stored nutrients help the lawn return greener in spring.



Why Early Lawn Fertilization Helps Grass Thrive



Grass needs nutrients during early growth stages to build strong roots and healthy blades.


The National Association of Landscape Professionals explains that early season fertilization supports stronger turf development and improves lawn density.


Thicker lawns have several advantages:


  • They crowd out weeds naturally

  • They tolerate foot traffic better

  • They hold moisture more effectively

  • They resist disease and stress



The Kickstarter Round begins that process.



Why Preventing Crabgrass Matters



Crabgrass is one of the most frustrating weeds homeowners face. Once it spreads, it can quickly take over thin areas of the lawn.


Preventing crabgrass early is much easier than controlling it later.


Pre emergent products work by preventing weed seeds from establishing roots. However, they must be applied before germination begins.


This timing is why lawn services start before weeds are visible.



What Homeowners Can Expect After the First Treatment



The Kickstarter Round is not about instant results. Instead, it sets the foundation for the rest of the season.


Over the next several weeks homeowners may notice:


  • Grass gradually greening as temperatures rise

  • Existing weeds beginning to decline

  • Fewer new weeds appearing

  • Stronger turf growth heading into spring



Consistent treatments throughout the year continue building on that progress.



Simple Tips to Support Your Lawn After Treatment



While professional lawn treatments provide the foundation, a few simple practices can help maximize results.



Avoid Early Mowing Stress



Allow grass to grow slightly taller early in the season. Taller blades help shade the soil and support deeper roots.



Water When Needed



Spring rain often provides enough moisture, but lawns benefit from occasional deep watering if conditions become dry.



Keep Foot Traffic Light



New grass growth is vulnerable early in the season. Reducing heavy traffic helps roots establish properly.



Starting Lawn Service Now Makes Spring Easier



Many homeowners wait until weeds appear or lawns begin looking thin before taking action.


By then, weeds already have a strong foothold.


Beginning lawn treatments with the Kickstarter Round prevents those problems before they start. Early feeding, weed prevention, and targeted treatments help lawns grow thicker, greener, and healthier throughout the season.


Homeowners who want a lawn that looks great without constant frustration benefit from a proactive approach.

A great lawn is built step by step. The Kickstarter Round simply begins the process.


With the right timing and a strategic plan throughout the year, homeowners can enjoy a lawn that feels good under bare feet, looks great from the curb, and holds up to kids, pets, and everyday life.
