A healthy lawn doesn’t happen with a single fertilizer application. It requires the right treatments at the right time of year to support healthy roots, manage weeds, and help turf recover from seasonal stress.
If you’ve ever wondered why lawn care companies make several visits throughout the year, the answer is simple: your lawn’s needs change with the seasons. Understanding what each application does can help you get the most from your investment and keep your property looking its best.

A Look at Ray’s Custom Lawn Care Program
Ray’s Tree & Lawn Care offers a five-application lawn care program designed specifically for lawns in the St. Louis area.
Early Spring Prevention Application
As the lawn begins waking up from winter dormancy, the focus is on preventing future weed problems while encouraging healthy early growth.
This application includes:
- Fertilizer
- Pre-emergent crabgrass prevention
- Broadleaf weed control when needed
Applying pre-emergent products before crabgrass begins growing helps reduce weed competition throughout the season.
Late Spring Nutrition Application
Once the lawn is actively growing, it benefits from additional nutrients.
This application includes:
- Organic-based slow-release nitrogen fertilizer
- Broadleaf weed control
Slow-release fertilizer provides nutrients gradually, helping promote steady growth rather than rapid flushes that may increase stress.
Mid-Summer Control Application
Summer can be challenging for cool-season grasses commonly found throughout Missouri.
During this visit, the focus shifts toward maintaining lawn health during hot weather.
Services include:
- Fertilizer
- Broadleaf weed control
- Optional grub control upon request
Rather than encouraging aggressive growth during periods of heat stress, treatments are designed to support the lawn while managing weeds.
Late Fall Winterization Application
The final application prepares the lawn for winter dormancy.
A high-nitrogen fertilizer is applied to encourage root development before cold weather arrives.
Benefits include:
- Stronger root systems
- Improved winter preparation
- Better spring green-up
- Healthier turf entering the next growing season
Core Aeration and Overseeding
Over time, soil naturally becomes compacted from foot traffic, weather, and normal use. Core aeration removes small plugs of soil, allowing air, water, and nutrients to move more easily into the root zone.
Overseeding introduces new grass seed into thinning areas, helping improve turf density and create a fuller lawn. Fall is generally considered the ideal time for aeration and overseeding because cooler temperatures and improved moisture support seed establishment.

Why Professional Timing Matters
One of the biggest advantages of a professional lawn care program is applying treatments when they’re most effective.
For example:
- Crabgrass prevention must be applied before seeds germinate.
- Broadleaf weeds are easier to control during active growth periods.
- Fall fertilizer supports root growth before winter dormancy.
- Aeration is most successful when turf can recover quickly.
Missing these seasonal windows may reduce the effectiveness of treatments.
Healthy lawns require more than occasional fertilizer. A well-planned seasonal lawn care program provides nutrients, manages weeds, supports root development, and helps turf recover from environmental stress throughout the year.
Whether your lawn needs routine fertilization, aeration and overseeding, grub control, or specialized treatments like deep root fertilization, choosing the right services at the right time can make a noticeable difference in long-term lawn health.
