Buying Guide for the Best Lawn Pre Emergents

Choosing the right lawn pre-emergent is crucial for maintaining a healthy and weed-free lawn. Pre-emergents are herbicides that prevent weed seeds from germinating, thus stopping weeds before they even start to grow. To pick the best pre-emergent for your lawn, you need to consider several key specifications. Understanding these specifications will help you make an informed decision that suits your lawn's specific needs and conditions.
Type of Weeds ControlledThis spec indicates which types of weeds the pre-emergent is effective against. It's important because different pre-emergents target different weeds. Common categories include grassy weeds like crabgrass and broadleaf weeds like dandelions. If your lawn is prone to a specific type of weed, choose a pre-emergent that is formulated to control that particular weed. For a more comprehensive approach, you might opt for a product that targets a broad spectrum of weeds.
Application TimingApplication timing refers to when you should apply the pre-emergent to your lawn. This is crucial because applying it at the wrong time can render it ineffective. Pre-emergents are typically applied in early spring or fall, depending on the weed type. For example, to prevent summer annual weeds like crabgrass, apply in early spring. For winter annual weeds, apply in the fall. Knowing the growth cycle of the weeds in your area will help you determine the best time to apply the pre-emergent.
FormulationPre-emergents come in different formulations, such as granular or liquid. This spec is important because it affects how you apply the product and its ease of use. Granular formulations are often easier to apply with a spreader and are less likely to drift, making them ideal for larger areas. Liquid formulations can be more precise and are often used for spot treatments or smaller areas. Choose the formulation that best fits your lawn size and your application preferences.
Duration of EffectivenessThis spec indicates how long the pre-emergent will remain effective after application. It's important because it determines how often you need to reapply the product. Duration can range from a few weeks to several months. For long-lasting control, look for a pre-emergent with a longer duration of effectiveness. If you prefer to reapply more frequently to ensure continuous protection, a shorter duration might be suitable. Consider your maintenance routine and how often you are willing to reapply the product.
Safety for Desired PlantsThis spec tells you whether the pre-emergent is safe to use around the plants you want to keep, such as grass, flowers, or shrubs. It's crucial because some pre-emergents can harm desirable plants if not used correctly. Look for products that are labeled safe for your specific type of grass or plants. If you have a mixed garden, choose a pre-emergent that is safe for a variety of plants to avoid accidental damage.
