In Northwest Ohio, spring weather can change quickly – and when soil temperatures rise, crabgrass isn’t far behind. The key to a clean, dense lawn in Ohio is applying the right product at the right time.

That’s why we recommend The Andersons 18-0-4 with Dimension® a professional-grade fertilizer combined with a broad-spectrum selective pre-emergent herbicide.

This product allows you to feed your lawn and prevent weeds in one efficient application.

What Is 18-0-4 with Dimension®?

The fertilizer analysis:

• 18% Nitrogen (N) – Drives spring green-up and turf growth
• 0% Phosphorus (P) – Ideal for established lawns and compliant with most phosphorus restrictions
• 4% Potassium (K) – Supports root strength and stress tolerance

The active ingredient, Dithiopyr (Dimension®), is a selective pre-emergent herbicide that prevents many annual grassy and broadleaf weeds. It also provides early post-emergent control of crabgrass up to the 1–3 leaf stage, giving you a wider application window.

Why Apply It?

1. Prevents Crabgrass Before It Germinates

Crabgrass begins germinating when soil temperatures reach 50–55°F. Once it emerges, control becomes more difficult and costly.

2. Builds Turf Density

The 18% nitrogen promotes early growth, helping turf thicken quickly. A dense lawn naturally crowds out weeds.

3. One-Pass Efficiency

Instead of separate fertilizer and herbicide applications, this combination saves time and labor while delivering professional results.

When to Apply in Northwest Ohio

In the Perrysburg area, pre-emergent timing typically falls between:

Late March through mid-April, depending on spring temperatures.

A good rule of thumb:

• Apply when soil temps consistently approach 50–55°F
• Often coincides with forsythia bloom

Because Dimension® offers early post-emergent crabgrass control, you have slightly more flexibility compared to older pre-emergent products, but earlier is still better than later.

For extended control through summer, some professionals use split applications spaced 6–8 weeks apart.

How to Apply for Best Results

1. Measure Your Lawn
Know your square footage to apply the correct rate.

2. Calibrate Your Spreader
Follow label guidelines carefully to avoid over- or under-application.

3. Apply Evenly to Dry Turf
Walk at a steady pace and avoid heavy overlap.

4. Water It In
Activate with about ½ inch of rainfall or irrigation within 7 days to establish the soil barrier.

Important Considerations

• Apply only to established turf
• Do not aerate after application
• Follow reseeding restrictions on the label
• Always follow label directions

In Perrysburg and throughout Northwest Ohio, early-season lawn care sets the tone for the entire year. Applying 18-0-4 with Dimension® at the proper time gives your lawn a competitive advantage by:

• Feeding turf for rapid green-up
