Buyer’s Guide: What to Consider
Choosing the right crabgrass preventer depends on your lawn size, grass type, and whether you need additional weed control or fertilization. Here are key factors to consider before making a purchase.
- Pre-emergent vs. Post-emergent: Pre-emergent preventers stop crabgrass seeds from germinating, so timing is critical—apply in early spring before soil temperatures reach 55°F. Post-emergent products kill existing crabgrass. Some products, like Jonathan Green, offer both, giving you more flexibility if you miss the ideal window.
- Grass type compatibility: Not all preventers are safe for every grass type. Most Scotts products are safe for all grasses except Dichondra and Bentgrass, while Preen works on a wider range including creeping bentgrass. Always check the label to ensure the product is suitable for your lawn to avoid damage.
- Fertilizer included: Some crabgrass preventers come with fertilizer, like The Andersons and Jonathan Green, which feed your lawn while preventing weeds. This can save you time and money, but if you already fertilize separately, a straight preventer like Scotts Halts may be more appropriate.
- Coverage area: Consider the size of your lawn. Products come in various bag sizes, from 10 lbs covering around 5,000 sq ft to 33.94 lbs covering much more. Buying a larger bag or a multi-pack can be more cost-effective for big lawns, but ensure you can store it properly.
- Weather resistance: Many preventers, such as Scotts Halts, are rainproof and won't be affected by snow or freezing temperatures after application. This gives you flexibility in timing, but always follow the label instructions for best results, especially if you expect heavy rain immediately after application.
Conclusion
Preventing crabgrass is all about timing and choosing the right product for your lawn. If you want a dedicated preventer, Scotts Halts is a reliable choice, especially in larger sizes or multi-packs for big lawns. For flexibility, Preen allows application up to 4 weeks after emergence, and Jonathan Green offers both pre- and post-emergent control.
If you prefer an all-in-one solution, Scotts Turf Builder Triple Action1 or The Andersons with fertilizer can save you time. Ultimately, consider your lawn’s specific needs and your schedule to pick the best crabgrass preventer for a lush, weed-free lawn.
