Crabgrass Preventer with Fertilizer: The Complete Guide

What is Crabgrass Preventer with Fertilizer?

Crabgrass preventer with fertilizer is a combination product that contains both a pre-emergent herbicide to prevent crabgrass from germinating and a fertilizer to promote healthy lawn growth. Pre-emergent herbicides work by creating a barrier in the soil that prevents crabgrass seeds from absorbing water and germinating, effectively halting their growth before they even emerge. The fertilizer component provides essential nutrients for your lawn, supporting healthy growth and improving overall appearance.

Benefits of Using Crabgrass Preventer with Fertilizer

Using a crabgrass preventer with fertilizer offers several key benefits:

• Prevents Crabgrass: Pre-emergent herbicides effectively prevent crabgrass from germinating, eliminating unsightly and invasive crabgrass patches.
• Fertilizes Lawn: The fertilizer component provides essential nutrients such as nitrogen, phosphorus, and potassium, promoting healthy lawn growth, lush green color, and improved density.
• Time-Saving: Crabgrass preventer with fertilizer combines two essential lawn care tasks into one, saving you time and effort compared to applying separate products.
• Cost-Effective: Purchasing a combination product is typically more cost-effective than buying separate crabgrass preventer and fertilizer.

Choosing the Right Crabgrass Preventer with Fertilizer

When selecting a crabgrass preventer with fertilizer, consider the following factors:

• Crabgrass Type: Determine the specific type of crabgrass prevalent in your area to choose a product formulated to control it effectively.
• Lawn Size: Calculate the square footage of your lawn to determine the correct amount of product to apply.
• Nutrient Needs: Assess your lawn's health and nutrient requirements to choose a fertilizer with appropriate levels of nitrogen, phosphorus, and potassium.
• Environmental Conditions: Consider local regulations and environmental concerns when selecting a product to avoid potential harm to soil, water, or wildlife.

How to Apply Crabgrass Preventer with Fertilizer

To effectively use crabgrass preventer with fertilizer, follow these steps:

1. Prepare Lawn: Before applying, mow your lawn to a height of 2-3 inches and remove debris.
2. Calibrate Spreader: Refer to the product label for recommended application rates and calibrate your spreader accordingly.
3. Apply Product: Apply the crabgrass preventer with fertilizer evenly over the entire lawn, following the instructions provided on the product label.
4. Water Thoroughly: After application, water the lawn deeply to activate the pre-emergent herbicide and provide moisture for nutrient absorption.

When to Apply Crabgrass Preventer with Fertilizer

The optimal time to apply crabgrass preventer with fertilizer is in the early spring, before crabgrass seeds germinate. In most regions, this falls between late February and early April, depending on local climate conditions. Reapply the product every 8-12 weeks throughout the growing season to maintain effective crabgrass prevention.

Tips for Effective Crabgrass Prevention

In addition to using crabgrass preventer with fertilizer, consider the following tips to enhance crabgrass control:

• Maintain a Healthy Lawn: Encourage a dense, thriving lawn by regularly mowing, watering, and fertilizing, providing unfavorable conditions for crabgrass growth.
• Remove Weeds: Regularly pull or spray existing crabgrass plants to prevent seed production and further spread.
• Avoid Overwatering: Excessive watering creates favorable conditions for crabgrass germination and growth. Water deeply and infrequently to encourage a healthy root system.
• Promote Turfgrass Density: Use turfgrass varieties known for their competitiveness against crabgrass, such as tall fescues, perennial ryegrasses, and Kentucky bluegrasses.
