    How to use

    How to use

    1. Aerate lawn in early spring. Rake and remove debris.

    2. Apply this product  only on established lawns.

    • Apply with spreader.
      - Use spreader settings for your brand/model. Too much fertilizer can burn the lawn.
      - Do not apply by hand.
      - Fill spreader on a solid surface (not lawn). Sweep to remove any spillage.
      - Guaranteed burn-proof when used according to label directions.
    • To ensure uniform coverage, spread fertilizer over entire surface in a criss-cross pattern, first applying lengthwise, and then widthwise.
      - Close the spreader when stopping or turning.

    3. Spot check lawn for bare spots. Where necessary, prepare the soil and apply C-I-L® Grass Seed.

    4. Water fertilizer in to ensure maximum absorption.

    When to apply

    Spring and summer: Apply only on established lawns every 4-6 weeks throughout spring and summer.
    Fall: This product is designed to improve resistance to cold winter conditions and promote early spring growth and green-up.



    • Apply in the spring to help prevent weeds.

    • Use correct spreader setting for the brand/model you have.
