What Is Weed and Feed Fertilizer?

Weed and feed fertilizer is a combination product designed to kill existing weeds while also fertilizing your lawn to promote healthy growth. It typically contains three main components: a herbicide to control weeds, a fertilizer to nourish the grass, and sometimes an insecticide to combat lawn pests. These products come in granular form and are applied using a spreader.

The primary benefit of weed and feed is its convenience. Instead of applying herbicide and fertilizer separately, you can address two lawn care needs with a single application. This saves time and effort, making lawn care more manageable, especially for larger yards. However, it’s crucial to understand how weed and feed works and to use it correctly to avoid damaging your lawn or the environment.

Types of Weed and Feed

There are two primary types of weed and feed products, categorized by the type of herbicide they contain:

  • Pre-emergent weed and feed: These products prevent weeds from germinating. They create a barrier in the soil that kills weed seeds as they sprout. Pre-emergent weed and feed is best used in early spring or fall, before weed seeds begin to germinate. It’s effective against weeds like crabgrass, but it won’t kill existing weeds.
  • Post-emergent weed and feed: These products kill weeds that have already sprouted. The herbicide is absorbed by the weed’s leaves and stems, leading to its demise. Post-emergent weed and feed is best applied when weeds are actively growing, typically in spring or early summer. They are effective against broadleaf weeds like dandelions.

Some weed and feed products combine both pre- and post-emergent herbicides to offer a wider range of weed control. Always read the product label carefully to determine which type of weeds the product targets.

Key Ingredients and Their Roles

Understanding the active ingredients in weed and feed is essential for effective and safe application. Here’s a breakdown of common ingredients and their functions:

  • Herbicides:
    • 2,4-D: A common broadleaf herbicide. It’s effective against many common lawn weeds.
    • MCPP (Mecoprop): Another broadleaf herbicide often used in combination with 2,4-D.
    • Dicamba: A powerful broadleaf herbicide that can be effective against tough weeds, but can also damage sensitive grasses.
    • Atrazine: Primarily used on certain warm-season grasses like St. Augustine and zoysia.
    • Prodiamine: A pre-emergent herbicide used to control grassy weeds like crabgrass.
  • Fertilizers:
    • Nitrogen (N): Promotes green, leafy growth.
    • Phosphorus (P): Supports root development.
    • Potassium (K): Enhances overall plant health and disease resistance.
  • Other Ingredients:
    • Insecticides: Some products include insecticides to control lawn pests like grubs.
    • Granular Carrier: Inert materials that help distribute the active ingredients evenly.

Always review the product label to identify the specific active ingredients and their concentrations. This information will help you choose the right product for your lawn and ensure you’re applying it safely.

Choosing the Right Weed and Feed

Selecting the correct weed and feed product is crucial for achieving the desired results without harming your lawn. Here’s how to choose the right one: (See Also: how to get fertilizer in ark)

1. Identify Your Grass Type

Different grass types have different tolerances to herbicides. Applying a product designed for one grass type to another can cause significant damage. Before purchasing weed and feed, identify your lawn’s grass type. Common lawn grasses include:

  • Cool-season grasses: Kentucky bluegrass, perennial ryegrass, tall fescue.
  • Warm-season grasses: Bermuda grass, zoysia grass, St. Augustine grass, centipede grass.

The product label will specify which grass types the product is safe for. If you’re unsure of your grass type, consult your local extension office or a lawn care professional.

2. Determine the Weeds You’re Targeting

Not all weed and feed products are effective against all types of weeds. Some are designed to target broadleaf weeds, while others control grassy weeds. Identify the weeds present in your lawn. Are they broadleaf weeds like dandelions and clover, or grassy weeds like crabgrass? Knowing the weeds you need to control will help you select a product with the appropriate herbicide. Look for products that list the specific weeds they control on the label.

3. Consider the Timing

The timing of your application depends on the type of weed and feed you’re using and the weeds you’re trying to control. Pre-emergent weed and feed should be applied before weed seeds germinate, typically in early spring or fall. Post-emergent weed and feed should be applied when weeds are actively growing, usually in spring or early summer. Consider the weather forecast before applying; rain can wash away the product and reduce its effectiveness.

4. Read the Product Label Carefully

The product label is your most important resource. It provides detailed instructions on how to use the product safely and effectively. Pay close attention to the following:

  • Grass type compatibility: Ensure the product is safe for your grass type.
  • Weed control: Verify that the product targets the weeds you’re trying to eliminate.
  • Application rate: Use the recommended amount of product. Applying too much can damage your lawn, while applying too little may not be effective.
  • Application instructions: Follow the instructions for spreader settings and application techniques.
  • Safety precautions: Wear appropriate protective gear, such as gloves, eye protection, and a long-sleeved shirt and pants. Keep children and pets away from the treated area.
  • Watering instructions: Some products require watering after application, while others do not.
  • Re-entry time: Note the time you need to wait before people and pets can re-enter the treated area.

5. Consider Environmental Factors

Think about the environmental impact of your choice. Some herbicides can leach into groundwater or harm beneficial insects. Look for products with lower environmental impact or consider organic alternatives. Always follow the manufacturer’s instructions for safe handling and disposal.

How to Apply Weed and Feed: Step-by-Step Guide

Applying weed and feed correctly is essential for achieving optimal results and avoiding damage to your lawn. Here’s a step-by-step guide:

  1. Prepare Your Lawn: Before applying weed and feed, mow your lawn to the recommended height for your grass type. This allows the herbicide to reach the weeds more effectively. Remove any debris, such as leaves and twigs, that could interfere with the application.
  2. Choose the Right Spreader: Select the correct type of spreader for your lawn size and the product you’re using. A broadcast spreader is suitable for larger lawns, while a drop spreader is better for smaller areas and more precise application. Make sure the spreader is clean and in good working order.
  3. Calibrate Your Spreader: Properly calibrating your spreader ensures you apply the correct amount of product. Refer to the product label for the recommended application rate. Set the spreader to the setting specified on the label. Test the spreader on a small, measured area to confirm the setting is accurate.
  4. Put on Protective Gear: Always wear appropriate protective gear when handling weed and feed. This includes gloves, eye protection, and a long-sleeved shirt and pants.
  5. Load the Spreader: Fill the spreader with the weed and feed product. Be careful not to spill any product.
  6. Apply the Weed and Feed: Apply the product evenly over the lawn, following the manufacturer’s instructions. Overlap each pass slightly to ensure complete coverage. Avoid applying the product on windy days, as the granules can drift and affect unintended areas.
  7. Water (If Required): Some weed and feed products require watering after application to activate the herbicide. Follow the watering instructions on the product label.
  8. Keep People and Pets Off the Lawn: Allow the treated area to dry completely before allowing people and pets to re-enter. The product label will specify the re-entry time.
  9. Monitor Your Lawn: After applying weed and feed, monitor your lawn for results. It may take several weeks to see the full effects. If you’re not seeing the desired results, review your application technique and the product label.
  10. Repeat if Necessary: Depending on the product and the weeds you’re targeting, you may need to apply weed and feed more than once per year. Always follow the product label’s instructions for repeat applications.
