When and Why to Apply Pre-Emergents: A Guide to Effective Lawn Care
For homeowners and gardeners alike, maintaining a lush, green lawn requires strategy, especially when it comes to controlling weeds. Pre-emergent herbicides play a pivotal role in preventing unwanted weeds from taking over your yard. But what exactly are pre-emergents, and when should you apply them? Let’s dive into the key considerations for using pre-emergents effectively.

What Are Pre-Emergent Herbicides?
Pre-emergent herbicides are specialized chemicals designed to prevent weed seeds from germinating. Unlike post-emergent herbicides, which target weeds after they’ve already sprouted, pre-emergents create a chemical barrier in the soil that stops weeds from emerging in the first place. They are most effective against annual weeds like crabgrass, goosegrass, and some broadleaf species.

Why Should You Use Pre-Emergents?
1. Proactive Weed Control: Preventing weeds from germinating saves time and effort compared to manually removing or treating established weeds.
2. Healthier Grass and Plants: Without weeds competing for nutrients, water, and sunlight, your lawn and plant beds can thrive.
3. Cost-Effective: Applying pre-emergents can be more economical in the long run, reducing the need for multiple treatments throughout the growing season.

When to Apply Pre-Emergents
Timing is everything when it comes to pre-emergent herbicides. The application window depends on the type of weeds you’re targeting and your local climate.
1. Spring Application:
o Target: Summer annual weeds like crabgrass and goosegrass.
o Timing: Apply when soil temperatures consistently reach 50°F for several days. This typically occurs in late winter to early spring, depending on your region. In the southeastern United States, for example, this might be in February or March. We usually apply in mid-February with great success for bed applications.
2. Fall Application:
o Target: Winter annual weeds like chickweed and annual bluegrass.
o Timing: Apply when soil temperatures drop to around 70°F. This often happens in late September to early October.
3. Use a Soil Thermometer:
o A simple soil thermometer can help you pinpoint the ideal time to apply pre-emergents. Consistency is key, as applying too early or too late can reduce effectiveness.

Applying Pre-Emergents in Plant Beds
Pre-emergents are not just for lawns—they can be used effectively in plant beds to prevent weeds. However, extra caution is required to avoid harming desirable plants, especially perennials.
1. Choose the Right Pre-Emergent: Look for a product labeled safe for use in plant beds and around ornamental plants. Some pre-emergents are specifically designed for use in landscaped areas.
2. Timing Matters: Apply pre-emergents to plant beds during the same windows recommended for lawns (spring and fall) to target seasonal weeds.
3. Avoid Damage to Perennials: Many pre-emergents can inhibit root growth. Be careful not to apply pre-emergents too close to the root zones of established perennials, as this can stunt their growth or cause harm.
4. Prepare the Beds: Remove any existing weeds and debris before application. This ensures the herbicide barrier works effectively.
5. Mulch After Application: Apply a layer of mulch over the treated area to enhance weed prevention and reduce the likelihood of the herbicide being washed away.
6. Follow Product Instructions: Ensure you’re using the correct application rate for plant beds and that the pre-emergent is activated with water as directed.

How to Apply Pre-Emergents
1. Choose the Right Product: Different pre-emergents target specific weeds, so read the label carefully.
2. Prepare Your Lawn or Plant Beds: Clear the area of debris and weeds. Ensure the soil is ready to absorb the herbicide.
3. Follow Label Instructions: Proper application rates and methods are crucial. Over-application can harm desirable plants, while under-application reduces effectiveness.
4. Water It In: Most pre-emergents need to be watered in to activate the chemical barrier in the soil. Check the product instructions for specifics.

Common Mistakes to Avoid
1. Late Application: Applying pre-emergents after weeds have germinated will not be effective.
2. Overuse: Applying too much can damage your lawn or plants and lead to runoff into nearby water sources.
3. Skipping Areas: Inconsistent application can create gaps where weeds can thrive.
4. Neglecting Perennials: Be mindful of established plants and avoid applying pre-emergents near their root zones to prevent damage.
