Buying Guide: Key Purchases For Crabgrass And Lawn Weed Control
What to consider when choosing lawn fertilizer and crabgrass killer:
- Pre-emergent vs post-emergent: Pre-emergents stop crabgrass seeds from germinating; post-emergents kill existing weeds. For crabgrass prevention, pre-emergent products are essential in early spring and fall.
- Coverage area: Choose a product that fits your lawn size. Apply equal to or slightly under your lawn’s square footage to avoid waste.
- Grass type compatibility: Some formulations are not suitable for certain grass varieties. Check the label for compatibility with your turf (Bermuda, Kentucky bluegrass, fescue, etc.).
- Weed spectrum: If you have multiple weed species (dandelion, clover, chickweed), consider a 5-in-1 or broad-spectrum product to reduce multiple applications.
- Feeding needs: If your lawn looks thin or pale, a product with fertilizer helps promote green, thick turf alongside weed control.
- Application timing: Spring applications target germinating weeds; fall applications prepare the lawn for winter and reduce winter weeds.
- Environmental considerations: Follow label directions to minimize runoff and protect surrounding plants and waterways.
Frequently Asked Questions
- What is the difference between a pre-emergent and a weed-and-feed product?
– A pre-emergent stops weed seeds from germinating, while a weed-and-feed product both feeds the lawn and controls or prevents weeds. - When should I apply crabgrass preventers?
– Apply in early spring before soil temperatures reach levels that support crabgrass germination, and again in fall for winter weeds in many regions. - Can I use multiple products together?
– It’s usually best to space applications per label instructions. Using multiple products simultaneously can cause over-fertilization or chemical interactions. - Will these products harm my existing lawn?
– When used as directed for your grass type and lawn size, most products are safe. Always follow label guidelines to avoid damage. - Is post-emergent treatment necessary if I use a pre-emergent?
– If crabgrass or other weeds have already germinated, a post-emergent treatment may be needed in addition to pre-emergent prevention for ongoing control. - How long does it take to see results?
– Some products start working within days, while others may take a couple of weeks. Read the product label for expected timelines.
