Prodiamine Application Rate for 1000 Sq Ft: How Much Prodiamine Do You Need for Your Lawn?

Prodiamine is a popular pre-emergent herbicide widely used for controlling annual grassy weeds like crabgrass, as well as certain broadleaf weeds in lawns and landscape beds. Knowing the proper application rate for your specific lawn size is crucial to achieve effective weed control without causing harm to your turfgrass. For 1,000 square feet, the recommended prodiamine application rate commonly ranges from 0.183 to 0.83 ounces of active ingredient, depending on your target weeds, region, and grass type. Most granular products are formulated for ease of use, with label instructions stating, for example, 1.5 to 4 lbs of product per 1,000 sq ft. Liquid concentrates typically require precise measurement—always use calibration tools and follow the product’s label.

From a designer’s perspective, maintaining a weed-free lawn not only preserves curb appeal but also ensures that your landscape’s layout, symmetry, and texture remain uninterrupted. When planning a full outdoor transformation, selecting the right herbicide and adhering to application guidelines is as essential as choosing your plant species or paving material. Many professionals rely on a precise 3D floor planner for visualizing exterior spaces, ensuring optimal placement and ongoing care practices for every element—including weed management strategies.

Tips 1:

Apply prodiamine before weeds germinate, typically in early spring or fall. Water-in the product with at least 0.5 inches of irrigation. Never exceed label rates—more isn’t better. Rotate with other pre-emergents to reduce resistance, and consider your lawn’s species, as some grass types are more tolerant than others. For best results, split the dose if targeting long germination periods.
