Why Fertilize Your Lawn?

  • Encourage grass growth to keep weeds and moss at bay, thereby avoiding the use of chemicals.
  • Gives your grass the ability to re-cover damaged areas quickly.
  • Encourages strong, healthy growth to minimize diseases.
  • Encourages deep roots that help to tolerate drought and other stress conditions.
  • To encourage a thick, dense, and green lawn that is a pleasure to lie on!


When is the Right Time to Fertilize and Overseed?

  • Your first fertilizer application should be made between April and May, just before the heat of summer arrives. A feeding of slow release nitrogen (SRN) will allow the plant to rebuild it's energy reserves to help tolerate the stresses of summer, including drought, heat, disease and insects. A percentage of SRN can feed the grass for 6-8 weeks.
  • A second application of fertilizer should be scheduled between July and August. Try and time your application prior to a rainfall to ensure that the product gets adequately watered in.
  • A third application, scheduled for September, should be made to encourage the roots to build sugars, or root reserves, to help it to overwinter.
  • Overseeding, in addition to fertilizing, is also important in encouraging a thick lawn. Early spring and early fall is the best time to overseed. Be sure to pick a seed mixture that is suitable to your environment.
