There are at least 11 states that ban phosphorus fertilizer use or sale. Luckily, many lawn weed and feed products available have adapted to this and have removed phosphorus from the product. Don’t worry—the weed and feed will still green up and thicken the grass without the additional phosphorus.
Cool-season turfgrasses grow best with average soil temperatures between 60 and 75 Fahrenheit. Cool-season grasses thrive in the cooler climates of the Midwest and Northern regions of the United States. Some cool-season grasses are Kentucky bluegrass, perennial ryegrass, and tall and hard fescue.
Ahead, read our guide to understanding weed-and-feed products, as well as the details on our top-favorite picks among the best weed-and-feed options available.
Fertilizers can also contain secondary elements and micronutrients needed for healthy growth such as sulfur, calcium, magnesium, boron, iron, molybdenum, zinc, copper, chloride, nickel, and manganese.
To grow a lush lawn, your soil needs to have essential nutrients. Fertilizers temporarily add nutrients to the soil. Fertilizers denote their nutrient ratios as NPK. This denotation represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the product. This is how the nutrients help grass:
Many fertilizers also have built-in herbicides or weed preventatives. Some products are better at killing certain types of weeds and pests than others. In general, most weed and feed target common types of broadleaf weeds including plantain, chickweed, creeping charlie, dandelions, and clover.

Now the Scotts does have Sulfur and that is an important element, so I have to give them that one, but look at all the other minor nutrients that Flagship delivers for you.
I can also tell you that Flagship works. My DIY friends all over FaceBook are posting results pics nearly everyday.
If you want to know the secret, that’s really it. I formulate my DIY lawn fertilizers to work VERY well at low rates. Throwing down less and getting the same results – let’s take a look.
If You Have a 5,000 Sq Ft Lawn
What About Bio-Nite?
Boron, Copper, Manganese, Molybdenum and Zinc. You will find those in short supply in many soil tests and here they are, riding along with the Nitrogen, Potassium and iron.
With Flagship, however, I go a step further and add 10% of my filler as Bio-Nite. Bio-Nite is the Florida version of Milorganite and it contains additional slow release nutrients, including additional chelated iron, calcium and some other goodies. These are not claimed on the label because we use them as filler – but they are still there and they deliver the smell of success in the fert.
I’ve done posts like this before but it came up again recently when I was talking this weekend about the “Easiest Way To Get a Green Lawn, Fast.” In that video I talk about the 3 primary elements you want to look for in any fertilizer if you want to get your lawn green.
