Every homeowner dreams of a thick, green carpet of grass. To get there, you often need to tackle two problems at once: feeding your lawn and controlling weeds. That’s where finding the best weed and feed becomes your most important task this season.
This guide will help you choose the right product and use it correctly. We’ll cover the different types, when to apply them, and how to avoid common mistakes.
By the end, you’ll have a clear plan for a healthier, more beautiful yard.
Best Weed And Feed
So, what makes a product the “best”? It’s not one-size-fits-all. The best weed and feed for your neighbor might be wrong for you. It depends on your grass type, the weeds you have, and your local climate.
These products combine fertilizer (the “feed”) with herbicides (the “weed” control). The goal is to nourish the grass you want while eliminating the plants you don’t.
Understanding the Two Main Types
You’ll primarily choose between two formulations: granular and liquid. Each has it’s pros and cons.
Granular Weed and Feed
This is the most common type. It looks like small pellets you spread with a broadcast or drop spreader.
- Pros: Easier to apply evenly for most homeowners. Often slower-release, feeding the lawn over time. Less risk of drift affecting flower beds.
- Cons: Requires watering to activate. Can be messy if spilled. The spreader needs calibration for even coverage.
Liquid Weed and Feed
This is a concentrate you mix with water and spray onto your lawn.
- Pros: Fast absorption through leaves (foliar feeding). Good for targeting specific weed patches. No spreader needed.
- Cons: Risk of spray drift killing nearby plants. Requires a sprayer. Often needs more frequent application.
Key Ingredients to Look For
Reading the bag or bottle is crucial. Here’s what those numbers and names mean.
The Fertilizer Part (N-P-K)
The three numbers on the package (like 24-0-6) represent Nitrogen (N), Phosphorus (P), and Potassium (K).
- Nitrogen (First Number): Promotes green, leafy growth. This is the most important for color and density.
- Phosphorus (Second Number): Supports root development. Many soils already have enough, so it’s sometimes low or zero.
- Potassium (Third Number): Strengthens plants against drought, disease, and cold weather.
The Herbicide Part
This targets weeds. You need to match the herbicide to your weed type.
- For Broadleaf Weeds (Dandelions, Clover, Plantain): Look for products containing 2,4-D, Dicamba, or MCPP. These are common in “weed and feed” for established lawns.
- For Grassy Weeds (Crabgrass, Foxtail): Look for pre-emergent herbicides like Pendimethalin or post-emergents like Quinclorac. Not all combo products handle grassy weeds.
Step-by-Step: How to Apply Weed and Feed
Doing this right makes all the difference. A poor application wastes money and can harm your lawn.
Step 1: Prepare Your Lawn
Mow your lawn 2-3 days before application. Set the blade to your normal height. Don’t mow right before, as you want more leaf surface for the herbicide to stick to.
Water your lawn deeply a day or two before if the soil is dry. You want the grass moist but not soggy at application time.
Step 2: Check the Weather
This is critical. Apply granular products when no rain is expected for 24-48 hours. You need time to water it in yourself.
Avoid windy days, especially for liquids. Temperatures should be between 60°F and 85°F for optimal results and to avoid stressing the grass.
Step 3: Calibrate Your Spreader
For granular products, follow the spreader settings on the bag. Test the spreader on your driveway to see the spread pattern and adjust the flow rate.
Fill the spreader on a hard surface, not on the grass, to avoid accidental spills.
Step 4: Apply Evenly
Walk at a steady pace. Overlap your passes slightly to avoid missed strips. Many people make the mistake of applying to much in one area, which can burn the grass.
Go around the perimeter of your lawn first, then fill in the middle in straight lines.
Step 5: Watering In
For granular weed and feed, you must water the lawn after application. This washes the granules off the grass blades and into the soil, activating both the fertilizer and herbicide.
Use about 1/4 to 1/2 inch of water. A rain gauge or empty tuna can helps you measure.
When is the Best Time to Apply?
Timing is almost as important as the product itself.
- Early Spring: Focus on fertilizer with a pre-emergent for crabgrass. Most weeds aren’t actively growing yet, so a full “weed and feed” may be less effective.
- Late Spring / Early Summer: Ideal for post-emergent weed control. Weeds are young and actively growing, making them vulnerable. Use a product suited for warm-season grasses if you have them.
- Early Fall: The absolute best time for feeding cool-season grasses. The fertilizer strengthens roots for winter. Combine with broadleaf weed control if needed.
- Late Fall: A winterizing fertilizer (high in potassium) is good, but weed control is usually ineffective as plants go dormant.
Common Mistakes to Avoid
Even experienced gardeners can slip up. Here’s what to watch for.
Mistake 1: Applying at the Wrong Time
Putting down weed and feed during a heatwave or drought stresses your lawn. The herbicides can damage grass that’s already struggling.
Mistake 2: Over-Applying
More is not better. It can chemical burn your lawn, kill beneficial soil life, and pollute waterways. Always follow the label rates exactly.
Mistake 3: Using the Wrong Product for Your Grass
Some herbicides are safe for Kentucky Bluegrass but will harm St. Augustine or Centipede grass. Know your grass type before you buy.
Mistake 4: Ignoring the Soil
Weed and feed is a quick fix, not a soil builder. If your soil is compacted or unhealthy, weeds will keep coming back. Consider core aeration and adding organic matter like compost.
Natural and Organic Alternatives
If you prefer to avoid synthetic chemicals, you have options. These methods require more patience and consistency.
- Corn Gluten Meal: A natural pre-emergent that inhibits weed seed germination. It also contains some nitrogen. Apply in early spring and early fall.
- Organic Fertilizers: Use products based on manure, compost, or meals (like alfalfa or soybean). They feed the soil microbiome, which in turn feeds your grass.
- Spot Treatment for Weeds: Use a vinegar-based herbicide or manually pull weeds. For persistent weeds, a flame weeder can be effective in driveway cracks.
- Promote Healthy Grass: The best defense is a thick lawn. Mow high, water deeply but infrequently, and overseed thin areas each fall.
Safety and Environmental Tips
Using these products responsibly protects your family, pets, and local ecosystems.
Keep children and pets off the lawn until the product has been watered in and the grass is completely dry. Store leftover product in its original container, out of reach.
Never apply near waterways, drainage ditches, or storm drains. Sweep any granules that land on driveways or sidewalks back onto the lawn.
FAQ Section
How soon can I mow after applying weed and feed?
Wait at least 2-3 days after application. This gives the herbicide enough time to be absorbed by the weed leaves.
Can I apply weed and feed to a new lawn?
No. You should wait until a new lawn has been mowed at least 4 times. The herbicides can damage tender young grass seedlings.
Is it okay to use weed and feed if I plan to overseed?
Most weed and feed products will prevent grass seeds from germinating. You should overseed in the fall and use a regular starter fertilizer, then apply weed control separately in the spring.
Why do I still see weeds after application?
Some tough weeds may need a second application in 4-6 weeks. Also, ensure you applied it evenly and watered it in properly. Weeds under stress from drought may not absorb the herbicide well.
What’s the difference between weed and feed and just fertilizer?
Fertilizer only provides nutrients. Weed and feed adds herbicides to kill existing weeds or prevent new ones, offering a two-in-one solution.
Can I use a weed and feed on any grass type?
Always check the label. Products formulated for cool-season grasses (like fescue or bluegrass) can harm warm-season grasses (like Bermuda or Zoysia), and vice versa.
Final Thoughts on Lawn Care
Choosing the best weed and feed is a smart step, but it’s just one part of lawn care. Consistent maintenance is what truly leads to a lush, green lawn.
Regular mowing at the proper height, deep watering, and annual aeration will do more for your lawn’s health than any single product. Think of weed and feed as a helpful tool, not a magic solution.
Start by identifying your main weed problem and your grass type. Then, select a product that matches. Follow the instructions carefully, pay attention to timing and weather, and you’ll be on your way to seeing great results in just a few weeks.
