Frequently Asked Questions

  • What does fertilizer actually do?

    Fertilizing is necessary to replenish the nutrients that your lawn consumes throughout the growing season.  Fertilizing also forces new growth and encourages a lush, thick lawn. A healthy lawn will reduce the possibility of weed growth and minimize stresses brought on by disease, drought and high traffic..

  • Why does a lawn need nitrogen?

    Your lawn will consume more nitrogen than any other nutrient.  Nitrogen gives grass its dark green color and rich look.

  • How do I maintain healthy and thick turf?

    By using a recommended fertilizer application program, such as the Menards Premium 4-application program, the products will supply your lawn with the nutrients needed to achieve a thick and lush lawn throughout the growing season.

  • What is soil pH?

    pH measures the amount of acidity or alkalinity in the soil. Turf grass prefers not to be very acidic.  If a soil test shows acidity, apply recommended amounts of limestone to reduce the acidity levels in the soil.

  • Why are there whitish-gray spots on my lawn in spring?

    This is usually caused by heavy snow in the winter. It is called snow mold, and will go away after a light raking, fertilizing, and mowing. This condition is best prevented by mowing the lawn fairly short in the fall

  • At what height should I mow the lawn?

    The mowing height of grass will change during the year. In early spring, grass may be kept shorter than when it gets very warm. A good rule is 2.5 inches from spring through mid-June. From mid-June to the end of August, 3 inches is recommended. After the first of September, take the height down by half an inch every two weeks until you have it at 1.5 inches going into winter.

  • Do I need to maintain my Lawn Mowing Equipment?

    Sharpen your mower blades frequently so they do not tear the grass blades (torn blades give the lawn a whitish cast).

  • Suggested Mowing Heights

    Bahiagrass: 2 to 3 inches

    Bentgrass: 3/8 to 3/4 inches

    Bermudagrass: 1/2 to 1 1/2 inches

    Bluegrass/Fescue Mix: 1 1/2 to 2 1/2 inches

    Blugrass/Ryegrass mix: 1 to 2 inches

    Carpetgrass: 1 to 2 inches

    Centipedegrass: 1 to 2 inches Fine Fescue Grass: 1 to 2 1/2 inches

    Kentucky Bluegrass: 1 to 2 1/2 inches

    Perennial Ryegrass: 1 to 2 inches

    St Augustine: 1 1/2 to 3 inches

    Tall Fescue: 3 to 4 inches

    Zoysia: 1/2 to 1 1/2 inches


  • How often should I mow?

    Lawns should be mowed frequently enough so that no more than 1/3 of the vertical height is removed with each mowing. This helps the plant maintain sufficient leaf area for quick recovery and continued growth. For instance: If the mowing height is 2 inches, mowing should be scheduled again before the lawn is 3 inches tall. Along with the height of mowing, the frequency of mowing is critical. The mowing schedule should be determined by how fast the grass is growing rather than by a routine weekly or 10-day schedule.

    • Mow when the grass is dry.

    • Best results are achieved with a sharp lawnmower blade

    • Alternate mowing direction

  • When should I stop mowing the lawn?

    Maintain the mowing schedule into the fall as long as the grass continues to grow. The lawn should go into winter at a lower height than it was maintained during the growing season.

  • What should I do with Grass Clippings?

    If the lawn is healthy, it is not necessary to remove grass clippings, assuming the grass clippings are able to drop into the lawn. In fact, leaving the clippings has positive benefits because they gradually decompose, feeding the lawn. It is important to note that clippings do not contribute to thatch. If a lawn is maintained very short, or if the clippings sit on top of the grass, remove them to avoid smothering the grass.

  • Should I water my lawn?

    If there is not adequate rain fall you may need to water your lawn to keep it in good condition.  The Midwest's climate, along with the natural ability of many turf grass plants to survive dry periods, often makes lawn watering optional. During spring and fall, natural precipitation is usually adequate to cause excellent growth and color. During summer when rainfall is often insufficient for plant growth, watering is recommended to promote vigorous growth and green color.  The average lawn will use about one inch of water per week depending on the time of the year and temperature.

  • How much should I water the Lawn?

    Water the lawn deeply and infrequently.  Water once a week or so during the summer (water less during cloudy and cool weather and more often when the weather is hot and windy).  Apply one inch of water at each watering.  Any rainfall during the week should be considered and watering should be reduced accordingly.


    Note: Proper watering methods will vary with soils. In heavy soils, slow heavy watering is essential (usually once a week). In sandy soils, frequent, lighter watering is the rule (maybe every day or two).

  • Am I not watering my lawn enough?

    To check if you are applying enough water, dig a hole with a trowel a couple of hours after watering.  The water should penetrate at least 8 inches.  Adjust your watering method as necessary.

  • How frequently should I water a new lawn?

    When a lawn is newly established from seeding or sodding or is affected with patch disease symptoms, frequent watering is necessary to keep it alive.
