Fertilization Why fertilize?

Fertilizing your lawn provides the nutrients necessary for your lawn to grow. However, maintaining a healthy and beautiful lawn during the entire growing season in Colorado can be a bit tricky. We have to account for wacky weather, a wide variety of soil compositions and grass types and those incessantly hardy weeds. With all of those things in mind, we follow a fertilization program that is customized to each "season" during the growing months in order to cut down on weeds and maximize the potential of your lawn. (We assess every lawn individually, and since each lawn is different and has specific needs, your fertilization program may not follow the example set forth below.)

Fertilizer is composed of (% nitrogen - % phosphorus - % potash or potassium)
Nitrogen is for grass growth.
Phosphorus is for root growth, the higher the % the stronger the root structure.
Potash or potassium is for grass strength and resiliency, the higher the % the stronger the cell walls of the leaf blades.
Iron (usually 2%) promotes green.

  1. Late Winter/Early Spring (March-Early April)
    Fertilizer composition is 19-3-7 with a 30% slow release (slow release helps feed the grass over time rather than all at once.)
    We apply Lesco Pre-M. This product will help prevent crabgrass and broadleaf weeds.
  2. Late Spring (Mid April-Early June)
    Fertilizer composition is 24-5-11 with a 25% slow release and 3% iron. Iron is added to this application to help the lawn green up.
    *If weeds are present, a weed and feed may be applied. Fertilizer composition is 22-5-7 with a 50% slow release and .01% iron. 5-10-31 with 10% iron might be used instead of above depending on drought conditions.
  3. Summer (June-Early August)
    Fertilizer composition is 24-5-11 with a 25% slow release and 3% iron. Iron is included in this application as well to keep your lawn green through the summer months. If weeds are present, a weed and feed may be applied. Fertilizer composition is 22-5-7 with a 50% slow release and .01% iron.
  4. Early Fall (Mid August-September)
    Fertilization composition is 32-5-7 with 50% slow release and no iron.
  5. Fall (Late September-Late October)
    Fertilizer composition is 24-8-15 with 50% slow release and no iron. This is an application which is high in potassium. This will strengthen the cell walls in preparation for winter.
  6. Late Fall/Winter (November-December)
    Fertilizer composition is 46-0-0. A straight nitrogen application, this "winterizer" is designed to promote residual nitrogen in the soil and ensure the turf has plenty of nutrients to use before and after dormancy.

Weed Control Weed Control Weed Control

Weeds are controlled throughout the season using a variety of post emergent products including (but not limited to) 3-Way to control selective broadleaf weeds and Avail to control non-selective broadleaf weeds.

Our fertilizers will be most successful if watered into the soil within 24 hours after application.
