Earth Science Timeline for Total Lawn Care

Each season brings opportunities for effective and efficient lawn care. By taking the right actions in the proper season, it is easy to maintain a vigorous, healthy lawn with a minimum of effort.

Spring into Action

Spring is the time to lay the foundation for a healthy lawn.

Mineral Soil Amendments

  • Early spring is a great time of year to apply mineral soil amendments to keep the soil healthy and soil pH in the proper range.
  • Earth Science Fast Acting Gypsum® helps improve soil structure and water infiltration, making it an ideal amendment for any type of soil. Gypsum also provides calcium and sulfur, essential plant nutrients, to the soil.
  • Maintaining proper soil pH (5.5 to 7.0 for most grasses) is important for good growth. A soil test can determine soil pH.
    • For soils that have an overly high pH (alkaline soil), use Earth Science Fast Acting Sulfur® to reduce the soil pH.
    • For soils with an overly low pH (acidic soil), use Earth Science Fast Acting™ Lime to naturally increase the soil pH.

Spring Fertilization Fundamentals

  • Fertilize cool season grasses in spring, once growth resumes.
  • Fertilize warm season grasses in late spring, once temperatures warm up enough for growth to begin.

Summer Success

Choose a summer lawn care strategy based on grass type

Lawn care needs in summer vary based on the type of lawn, with distinct differences between cool season lawns and warm season lawns.

  • Cool season grasses generally do not need fertilization in summer. Instead of fertilizer, Earth Science Fast Acting Iron® can provide a green-up to summer lawns without stimulating growth.
  • Warm season grasses benefit from summer fertilization, as they will actively grow during the summer season. Make one or two fertilizer applications in summer for warm season grasses.
  • Water as needed
  • Mow as needed

Fall Fundamentals

Fall care is key to future success

Fall is a critical period for lawn care and provides key opportunities for improving lawn success the following season.

  • For cool season grasses, fall is the most important time to fertilize. If you fertilize just once a year, make it in fall. Fall feeding helps lawns to build strong, deep root systems, improving performance once growth resumes in spring.
  • Fall is also the optimal time to overseed cool season lawns. Overseeding helps turn thin, weak grass into vigorous, thick lawns. Warm season lawns can be overseeded with cool season grasses to provide fall and winter color.
