Frequently Asked Questions

Most cool-season lawns in St. Louis County and St. Charles County thrive on a multi-application program spread across the growing season, typically four to six visits from early spring through late fall. We time each feeding to the season so your turf gets the right nutrients when it can actually use them.
Missouri lawns are mostly cool-season grasses like fescue and bluegrass, so the most important feedings come in spring and especially fall. Fall applications build deep roots and store energy for next year, while well-timed spring and early summer feedings support steady green-up without pushing weak, disease-prone growth.
Our programs deliver balanced nitrogen, phosphorus, and potassium matched to what your lawn needs. Nitrogen drives green color and growth, phosphorus supports strong roots, and potassium improves stress and disease tolerance. We lean on slow-release products so feeding stays steady instead of spiking and fading.
Yes. We feed based on what your soil and turf are telling us rather than applying the same blend everywhere. Soil-informed feeding lets us adjust nutrient balance for your property in O'Fallon, Wentzville, Cottleville, St. Charles, or the greater St. Louis area. Contact us to get started.
