Selecting a fertilizer and weed killer that’s compatible with your grass species will give you far better results. Different nutrients have different effects on your lawn, from enhancing color to developing stronger root systems. Additionally, since many products include herbicides or weed preventatives, it’s important to know the types of weeds that come up in your lawn.
The good news is that if your lawn looks a bit drab and weedy, you can bring it back to life by using “weed and feed” fertilizers and herbicides. Designed to introduce essential nutrients into the ground that accelerate the growth of your grass, these products help you maintain thick and healthy turf, while minimizing pesky lawn weeds.
What to Consider When Choosing the Best Weed and Feed
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:
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.
Warm-season turfgrasses grow best with average soil temperatures between 80 and 95 degrees Fahrenheit. Warm-season grasses thrive in warmer climates found in the Southeastern and Southwestern United States and include Bahia grass, Bermuda grass, carpet grass, Saint Augustine grass, and zoysia grass (Japanese lawn grass).
You can also test your soil for the micronutrient content. This ensures that the fertilizer that you choose has the best nutrient diversity for your lawn.
