Crabgrass Pre-Emergent

About

Crabgrass Pre-Emergent: Stop Weeds Before They Start Crabgrass can quickly take over your lawn if left unchecked, but with the right crabgrass pre-emergent, you can prevent it before it even has a chance to sprout. Pre-emergent herbicides create a barrier in the soil that stops crabgrass seeds from germinating, keeping your lawn weed-free and healthy all season long. When to Apply a Crabgrass Pre-Emergent Timing is critical when applying a pre-emergent crabgrass preventer. Apply before soil temperatures reach 55°F for three consecutive days, as this is when crabgrass begins to germinate. Depending on your region, this typically falls between late winter and early spring. To ensure season-long crabgrass pre-emergent control, a second application may be needed in late spring. Choosing the Best Pre-Emergent for Crabgrass Control We offer two premium pre-emergent crabgrass herbicide options, each designed to suit different lawn care needs: 0-0-7 Safeguard – Ideal for dormant lawns or situations where you only need a pre-emergent crabgrass killer without added nitrogen. Perfect for Bermuda, Zoysia, and other warm-season grasses before green-up. 13-0-10 Guardian – A crabgrass pre-emergent fertilizer that not only prevents weeds but also supplies nitrogen and potassium to feed your lawn. Best for cool-season grasses like tall fescue and Kentucky bluegrass in early spring. How Pre-Emergent for Crabgrass Works A pre-emergent crabgrass herbicide does not kill existing weeds—it prevents new ones from growing. Once applied, it forms a protective barrier in the soil. To activate this barrier, water it in with at least ½ inch of irrigation or rainfall within 48 hours of application. Take Control of Crabgrass Before It Starts Don't wait until it's too late!
