The Andersons 18-0-4 Barricade Fertilizer with Pre Emergent Weed Control
Active weed prevention is the core benefit here. The product blends an 18-0-4 fertilizer with prodiamine, a proven pre-emergent herbicide. It’s designed to prevent a wide range of weeds, including crabgrass and poa annua, while promoting thick, healthy turf. Best for medium lawns that need both feeding and weed prevention early in the season. A limitation is that it will not eliminate existing weeds, focusing instead on preventing new ones from germinating.
Sunday Weed & Green + Kit
This kit separates weed control from fertilizer for potentially better results. Weed & Green targets weeds early, while Lawn Kickstart provides fertilizer after weed control. Best for homeowners who want a two-step approach and up to 4,000 sq ft coverage per kit. It’s a good choice if you’re looking to minimize pesticide use with targeted early-season weed suppression. It may require multiple applications for larger or more established weed problems.
Lesco 19-0-6 Dimension Pre-Emergent Fertilizer
Lesco’s Dimension formula combines a pre-emergent herbicide with a strong nitrogen component, supporting lush green growth while preventing crabgrass and other annual grasses from germinating. It’s well-suited for homeowners who want reliable pre-emergent protection with steady early-season fertilization. A potential limitation is the reliance on Dimension for weed prevention—alternative products may cover a broader weed spectrum in some lawns.
GreenView Premium Formula Spring Lawn Fertilizer with Crabgrass Preventer
This GreenView bag covers up to 10,000 sq ft and uses a slow-release nitrogen system to provide up to six months of feeding. The included Dimension pre-emergent helps prevent crabgrass for up to 120 days and controls a broad set of common lawn weeds. Best for large yards needing a single, comprehensive spring treatment. A consideration is the relatively long protection window, which may be less ideal for those preferring more frequent seasonal adjustments.
GreenView Crabgrass Control Plus Lawn Food
This option combines pre-emergent weed prevention with essential nutrients in a 26-0-4 NPK formulation. It’s designed for up to 5,000 sq ft and using GreenSmart Enhanced Efficiency technology, which supports slow, steady feeding. Best for medium lawns needing reliable weed prevention and consistent green-up, with the caveat that coverage and timing should align with local weed pressure and climate.
Preen Garden Weed Preventer Plus Plant Food
Designed for garden beds, this product provides pre-emergent weed control and general plant food for over 200 plant varieties. It’s best for flower beds, ground covers, and landscape areas where weed prevention is needed without compromising ornamental plants. Useful for mixed landscapes, but not a substitute for lawn-specific pre-emergent fertilizer programs.
Buying Guide: Key Considerations For Spring Pre-Emergent Fertilizers
- Area coverage: Match product coverage to your lawn size. Larger yards benefit from bigger bags or those with extended coverage windows.
- Weed spectrum: Look for pre-emergents that target crabgrass, poa annua, goosegrass, and other local weeds. Some products also offer post-emergent components.
- NPK balance: Choose a formula with a nitrogen source that matches your lawn’s growth stage. Slow-release nitrogen provides steady color without excessive growth.
- Application timing: Pre-emergents are most effective when applied before weed seeds germinate. Timing depends on your climate and seasonal temperatures.
- Security of use: If you have gardens or ornamentals, ensure weed preventers are labeled for use near those plants, or choose separate lawn-focused products.
- Single vs. split applications: Some kits separate weed control from fertilization for tailored results. Consider your pest management approach and labor capacity.
Frequently Asked Questions
- What is a pre-emergent fertilizer? A product that combines fertilizer with a pre-emergent herbicide to prevent weed seeds from germinating while feeding the lawn.
- When should I apply pre-emergent for spring? Typically before soil temperatures reach weed germination thresholds, often in early spring. Timing varies by region.

- Is a weed-and-feed product better than a separate weed control and fertilizer? It depends on your lawn’s needs. Separate applications can offer better weed control and targeted feeding for certain landscapes.
- How long does a pre-emergent last? Protection duration varies by product but often ranges from 60 to 120 days, depending on climate and product formulation.
- Can I use these products on all grass types? Most products are formulated for common warm- and cool-season grasses. Always check label directions for compatibility with your grass type.
