Hello M –

Many states now ban or restrict the sale of lawn fertilizer containing phosphorus. The concern is that much of this nutrient spread on lawns and commercial farms is lost through erosion and runoff. Phosphorus that gets into nearby lakes, rivers and streams can contribute to algae blooms which starve our natural water courses of oxygen that plants and fish need (see Fertilizer Runoff Killing Gulf).

We offer two slow-release phosphate free lawn fertilizers that we feel are the best on the market. They are:

Dr. Earth Lawn Fertilizer (9-0-5) promotes a hardy root system and controls thatch buildup. Best of all, it contains mycorrhizae, beneficial fungi that enhance your lawn’s ability to absorb nutrients and water, to ensure that nutrients are made available to the grass roots, even under high stress conditions. Each 40 lb bag covers 4,400 square feet and last up to 3 months after application.

Ringer Lawn Restore II (10-0-6) provides the essential nutrients that produce thick, green lawns and deep, vigorous root systems. It is pelleted for easy application and OMRI Listed for use in organic production. Apply 4-8 lbs per 1,000 square feet with a drop or rotary spreader every 3-4 months.

Hope it helps!
