Convenient, Fast Acting & Effective: Crabgrass Barrier's pre-calibrated hose-end spray bottle makes application a breeze... Just screw the bottle onto your garden hose and you're ready to go. The bottle mixes the liquid and water in the correct levels automatically as you spray so there is no measuring or special tools required.

What to Put in It & What to Leave Out: One of the first decisions we made when developing our Crabgrass Barrier was what NOT to put in it. With more than 30 years in the lawn care business we knew that many popular crabgrass preventing products were made with harsh chemicals. We left all that stuff out and developed this effective, powerful treatment using a Botanical Oil Blend!

Purely Organic Products Crabgrass Barrier is supplied in a convenient pre-sealed and calibrated hose end bottle. For proper application follow the instructions below:

Pre-Emergent Treatment (For use before Crabgrass emerges). For use on established grass and turf only. 

  1. Connect the garden hose to the spray nozzle.
  2. Turn on water.
  3. Hold down the lock tab and turn the nozzle to the ON Position.

Application & Coverage: This 32 Oz. concentrated spray treats up to 3,500 Sq. Ft. For optimal results apply in spring/early summer to established turf grass before crabgrass emerges. Apply Crabgrass Barrier and allow to dry before seeding. Do not apply Crabgrass Barrier during seeding. 

Storage & Disposal: Store this product in its original container in a safe place. Store in a cool, dry, well-ventilated area, out of reach of children and animals. Dispose of contents and empty package in accordance with municipal regulations. Never discard any unused product in any indoor or outdoor drain. 

Important Note: The instructions above are for use as a guide only. For complete instructions for use and safety precautions review the back of your product package and the manufacturer's Material Safety Data Sheet.

A Well Fed Lawn is a Happy Lawn: Just like you, your lawn needs nutrient rich food to grow and flourish. We recommend feeding with one of our Lawn Food products about four times a year -- with the first feed in the early spring and the last in the late fall -- for a lush, healthy lawn.

Water Well & Often: Healthy, well fed, lawns are more efficient at absorbing water and nutrients. Water your lawn every few days to provide approximately 1" of moisture (including rainfall) per week. (A typical sprinkler takes 3-4 hours to provide 1" of water.)

Mow Like a Pro: Never remove more than 1/3 of the blade of grass when mowing. During times of stress (for instance in the hot summer) keep grass longer to protect the plant. Leaving clippings on the lawn allows plant nutrients to recycle back to the soil.
