    The predominantly silty soil (70%) in O'Fallon creates specific lawn care needs:

    • Watering habits: The silty soil retains moisture well but can compact easily. Water deeply but less frequently to encourage deep root growth.
    • Mowing height: Keep cool-season grasses taller (3-4 inches) during summer heat to reduce stress.
    • Fertilizing approach: With moderate phosphorus levels (33 ppm), focus on nitrogen for growth and color in your custom lawn plan.
    • Weed control: The rich organic matter supports healthy grass but can also feed weeds. Regular mowing helps prevent weed establishment.

    For best results with lawn care in O'Fallon, consider a soil test kit to fine-tune your approach. Your application schedule should align with Missouri's seasonal changes to maximize effectiveness.

      O Fallon, Missouri FAQs

      For O'Fallon's transition zone climate, focus on a four-season approach. Spring: Apply early nutrients and seed bare spots when temperatures reach 55-70°F. Summer: Water deeply but less frequently. Fall: Apply fertilizer, control weeds, and overseed for best results. Winter: Reduce watering and prepare for dormancy. Sunday custom plans take the guesswork out by delivering season-specific products timed perfectly for O'Fallon's weather patterns and soil conditions.

      For weeds, Sunday offers targeted products like Dandelion Doom that kill weeds down to the roots. Apply on sunny days when weeds are actively growing. For thin grass, overseed during fall when soil is warm but air is cool. Sunday's soil test helps identify nutrient deficiencies causing thin grass. Their fertilizers promote thicker growth that naturally crowds out weeds. Regular mowing at proper height and deep, infrequent watering also strengthen your lawn's defense against common problems.

      Sunday's DIY lawn care plans include custom-blended nutrients delivered throughout your growing season. You'll receive a soil test kit to analyze your lawn's specific needs, a sprayer for liquid nutrients, and easy application instructions. Plans range from basic nutrient delivery to comprehensive options with weed control, grass seed, and pet-friendly products. Everything is tailored to your lawn size, local climate, and soil conditions, with application dates specifically timed for O'Fallon's growing season.

      Yes! Sunday designs products with family safety in mind. Their ingredients break down quickly and don't linger in the environment. After liquid products dry or granular products break down, normal yard activity can safely resume. Sunday uses ingredients you can pronounce, many of which are also used by organic farmers. Their approach works with nature rather than fighting it, creating lawn care solutions that are effective while being mindful of kids, pets, and the planet.

      Traditional lawn care services can cost up to $1500 annually in O'Fallon. Sunday's custom lawn plans offer a more affordable alternative, starting between $55-$100 depending on your lawn size and plan level. Each plan includes custom fertilizer, soil testing, weed control options, and expert support from Yard Advisors. Most Sunday customers save hundreds yearly while getting a greener lawn that's safer for families, pets, and the environment.
