Lawn Fertilization: We apply a nitrogen-based liquid fertilizer five to six times a year, tailored to the weather and your lawn’s needs. We also apply broadleaf weed control in the spring and fall, pre-emergent weed control in the spring, and nutrients such as potassium, phosphorus, and iron throughout the year. We also include organic materials to help keep your lawn green, healthy, and weed-free. Prices start at $29.00 per application and are based upon the size of your lawn. The price for an average lawn (3,000 square feet) is $38.00.
