  • For optimum results we recommend 4 granular fertilizer applications 45-60 days apart.
  • A minimum of 2 treatments are crucial to maintain a lawns health quality.
  • More than 4 treatments of our fertilizer is unnecessary and environmentally irresponsible.
  • Fall application is the most important for your lawn’s health and ability to recover from winter come springtime.
  • Services are available “a la carte” – you are not locked into a “plan” you don’t want or need.

TIP: Request a fertilizer application 2-3 weeks before hosting a special event such as a wedding, party or having guests from out of town. Your lawn will look sensational!

  •  Leaf blades are flat & broad,  1/4 to 1/2 inch, two to five inches long,  sometimes hairy
  • Leaf sheaths are hairy & often purplish
