There's one technique (or rather a group of techniques) well suited for staying proactive with protecting your lawn: pre emergent weed control! The concept is simple: target the weeds before they have a chance to emerge and become a nuisance. Prevention is the best medicine, after all. It's not a one time fix, but more of a long term strategy to employ in the war on weeds.
This approach to weed management is particularly useful as it can help to maintain the aesthetic of your outdoor spaces and the health of your plantings. It works by creating a barrier that affects weed seeds at a crucial stage in their development, preventing them from ever becoming the eyesores that require pulling, hoeing, or chemical post-emergent treatments.
This article will go into depth on how this strategy works, and what best practices you can employ to consistently keep weeds out of your lawn and garden. If you need additional help, don't hesitate to call Lobb-Alexis. We have the tools and skills needed to plan and execute a pre emergent weed control strategy that will send crabgrass and dandelions running for the hills.

Understanding How Pre Emergent Weed Control Works
To truly appreciate the power of pre emergent weed control, it's essential to understand the science behind it. These herbicides are designed to disrupt the growth process of weeds at the germination stage. They don't prevent the seeds from germinating, but they stop the development of essential growth structures. As a result, the weed seedlings die before they can break through the soil surface and become visible.
The effectiveness of pre emergent weed control hinges on timing. The herbicide must be applied before weed seeds start to germinate, which typically occurs when the soil reaches a certain temperature and is sufficiently moist. This means that monitoring weather conditions is crucial for the success of this method. The herbicide creates a chemical barrier at the soil surface, and when applied correctly, it can be effective for several weeks or even months, depending on the product used.
One of the significant advantages of pre emergent weed control is that it targets weeds without harming established plants. Since it's aimed at seeds, your mature lawn, shrubs, or flowers are safe. This selectivity is why pre emergent treatments are a cornerstone of preventative lawn care and why they are so highly recommended by lawn care professionals.
Common Types of Pre Emergent Herbicides
There are two main categories to consider: synthetic and natural/organic herbicides. Synthetic pre emergents, such as pendimethalin, dithiopyr, and prodiamine, are widely used because of their effectiveness and longevity. They come in granular or liquid forms and can be applied using a spreader or sprayer. These are typically some of the most effective (especially when used as the instructions on the package advise) substances for weed control, but overuse can pollute your local ecosystem, especially during the rainy season.
On the other hand, for those who prefer a more eco-friendly approach, there are natural pre emergent options. These may include corn gluten meal, which has been found to suppress weed germination while providing the added benefit of fertilizing your soil. However, it's important to note that natural pre emergents may need to be applied more frequently and may not offer the same level of control as synthetic varieties.
Each type of herbicide will have specific instructions regarding application rates and timing, as well as safety precautions. Respecting these guidelines is crucial for the safety of the environment, pets, and humans, as well as for the effectiveness of the weed control program.
When and How to Apply Pre Emergent Weed Control
Timing is everything when it comes to applying pre emergent herbicides. Generally, you'll want to apply them in early spring before soil temperatures rise to the point where weed seeds begin to germinate. For most regions, this is when the soil temperature is consistently at or just above 55 degrees Fahrenheit. However, for some weeds, like crabgrass, you may need to apply pre emergent treatments even earlier.
The application process itself is straightforward, but it must be precise. For granular herbicides, you'll need a spreader to ensure even distribution over your lawn or garden beds. It's essential to follow the manufacturer's instructions for the rate of application to avoid under or over-application, both of which can lead to poor results and potential damage to your garden.
Watering is also a critical step in activating pre emergent herbicides. After applying the product, you'll usually need to water the area to help the herbicide penetrate the soil and form the protective barrier. Not following this step correctly can lead to a failure in weed control, so make sure you understand the requirements of the specific product you're using.
Pre Emergent Weed Control Tips and Best Practices
To maximize the benefits of pre emergent weed control, there are several tips and best practices you should follow. First and foremost, know your weeds. Different weeds have different growing seasons, and understanding this can help you time your applications more effectively. For instance, if you're dealing with summer annuals, you'll want to apply in late winter or early spring. For winter annuals, late summer or early fall applications will be more appropriate.
One of the best things you can do to prevent weeds is to simply care for your plants more! A healthy, strong plant means that it will eat up resources in the soil that weeds need to grow and reproduce. Fertilize, water, and mow your lawn regularly; anything your grass loves, weeds typically dislike. If your lawn is healthy and bushy enough, there simply won't be any room for weeds!
It's also essential to apply pre emergent herbicides uniformly across the entire area you want to protect. Missing spots can leave openings for weeds to grow. If you're unsure about how to do this, or if you're dealing with a large or complex landscape, it may be wise to seek professional help.
Conclusion
Staying on top of your weed problems before they rear their ugly, leafy heads is the best way to ensure the long-term health of your lawn and garden. We hope this guide gives you what you need to start building your pre emergent weed control strategy!
