Will Not Burn Your Lawn When Used as Directed: At Purely Organic Products we believe that plant and garden care products should be good for plants, and safe for pets and people when used as directed. Our Crabgrass Defender Lawn Food is made with natural ingredients, rather than harsh chemicals and mineral salts, so it won't burn or yellow your grass when used as directed. It is convenient and family friendly with no restrictions on re-entry time (for pets or people) after application.

What to Put in It & What to Leave Out: One of the first decisions we made when developing our Crabgrass Defender Lawn Food was what NOT to put in it. With more than 30 years in the lawn care business we knew that many popular fertilizer products were made with harsh chemicals, manure and even bio-solids (organic materials resulting from the treatment of domestic sewage – yes, you're reading that right).

We have picnics on our lawns, and our children and pets play on them, so we use natural, plant based ingredients to create our Lawn Food products.

No Added Phosphates: Purely Organic Products Crabgrass Control Lawn Food is made without added phosphates so it meets and exceeds local environmental regulations limiting Phosphate usage in municipalities across the USA. 

Effective Pre-Emergent Crabgrass & Weed Control: This combination product is designed to feed your lawn while preventing crabgrass and weeds – including Annual Bluegrass, Barnyard Grass, Black Medic, Black Nightshade, Buckhorn Plantain, Catchweed Bedstraw, Common Lambsquarters, Curly Dock, Dandelion, Giant Foxtail, Green Foxtail, Large Crabgrass, Orchard Grass, Purslane, Quack Grass, Redroot Pigweed, Shuttercane, Smooth Crabgrass, Velvetleaf, Wolly Cupgrass, and Yellow Foxtail. When used as directed it will not harm established turf grass, lawns and gardens. DO NOT APPLY TO FOOD CROPS.

Choose the Right Day: For best results apply Lawn Food with Crabgrass Defender on a calm day when no heavy rains are expected. This product should be applied in the early summer before crabgrass emerges; and in the fall as broadleaf weeds begin to establish root systems in preparation for spring growth.

Set Your Spreader: Set your drop or rotary spreader to deliver fertilizer at a rate of 4-8 lbs. per 1,000 sq. ft. of lawn. Individual spreader settings will vary; but common settings are listed below.

Apply: FOR LAWNS & TURF GRASS, work back and forth in steady rows, applying evenly across the entire treatment area. You may seed your lawn immediately after applying this product. FOR GARDEN BEDS, prepare beds by turning under or pulling established weeds prior to application. Sprinkle this product around plants after sprouts have true leaves and established root systems. Lawn Food with Crabgrass Defender may also be tilled directly into the soil.

Clean Up: Get the most out of your lawn care, and protect the environment, by sweeping excess or stray particles back onto the lawn.

Activate: After application, water lightly to activate. After the initial watering, let the lawn stay dry for 2-3 days for best results. Excessive rainfall or irrigation may require re-application.

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. 

Does This Fertilizer Need to be Watered in After Application? For the best results you should water your lawn or turf lightly after application to activate the fertilizer. If rain is due within 2-3 days of application then the fertilizer can be left on the lawn until the rain activates it.

What is the N-P-K Ratio of This Product? Crabgrass Defender Lawn Food has an NPK Rating of 10-0-2 or 10% Nitrogen (N), 0% Phosphorus (P), and 2% Potassium (K).

Why Aren't There Any Phosphates (Phosphorus) in Your Lawn Food? Many states and local municipalities restrict or prohibit the application of Phosphates on lawns and turf; because of the negative environmental impact of excess phosphorus on local water quality, plant and animal life.

Can I Use a Handheld Spreader with Lawn Food? We recommend using a rolling broadcast or drop spreader with our products because they tend to provide more even and measurable coverage. If you're planning to use a hand held spreader we recommend applying 4-5 pounds of fertilizer per 1000 square feet of lawn turf. (There are approximately 3 cups of fertilizer per pound.)
