How it Works

Great lawns are built by doing the right things at the right time. Sunco follows a simple seasonal approach, sending the right products when your lawn needs them so there’s no guesswork.

Spring

Pre-Emergent and Early Growth Fertilizer

Spring is about setting the foundation for the entire year. As soil temperatures rise, weeds begin to germinate long before you ever see them. A pre-emergent fertilizer works by stopping weed seeds from developing, which helps prevent problems instead of reacting to them later.

At the same time, early-season nutrients help wake the grass up from winter dormancy. This supports steady green-up without forcing excessive top growth too early.

Applying the right products in spring helps reduce weed pressure, improves lawn density, and creates a healthier base that carries through the rest of the season.

Summer

Maintenance Fertilizer and Stress Support

Summer lawn care is about maintaining strength during heat and stress. High temperatures, foot traffic, and mowing all put pressure on the turf. Summer fertilizers focus on feeding the lawn without overstimulating growth that can lead to burnout.

These products help maintain color, support root health, and improve the lawn’s ability to handle heat and drought conditions.

When applied correctly, summer treatments keep the lawn stable and resilient, instead of constantly trying to recover. Consistency during summer is key, which is why scheduled applications make a noticeable difference.

Fall

Recovery, Root Building, and Weed Control

Fall is one of the most important seasons for lawn care. Cooler temperatures allow grass to recover from summer stress and focus energy below the surface.

Fall fertilizers help strengthen roots, repair thinning areas, and improve nutrient storage for the following spring.

This is also an ideal time to address weeds that survived the summer. Fall applications help weaken those weeds before winter, making them easier to control long term.

What you do in fall directly impacts how well your lawn comes back next year.

Winter

Soil Health and Preparation

While grass growth slows in winter, the soil is still active. Winter treatments focus on improving soil conditions rather than pushing growth. These products support microbial activity and nutrient availability so the lawn is better prepared when spring arrives.

Winter is also when planning matters most. A proper winter application helps ensure your lawn is ready to respond quickly and evenly once temperatures rise again. Think of this season as preparation, not downtime.

I used to buy random bags from the hardware store and hope for the best. Sunco takes that whole problem off my plate. My lawn looked noticeably better after the first full season.

The timing is what sold me. I never knew when to apply what, and now I just open the box and follow the instructions. Easiest upgrade I have made to my yard.

We moved into a house with a patchy, weedy mess. After a year on the seasonal plan, my neighbors started asking what service I use. It is just Sunco.

I have a big yard and two dogs, so I figured a nice lawn was off the table. Sunco simplified everything and after one full season my grass has never been this thick.
