Why Crabgrass Is So Problematic

Crabgrass is Howard County's most frustrating weed. This annual germinates in spring, grows aggressively through summer, and produces 150,000 seeds per plant before dying in fall. Without prevention, each year's infestation gets worse.

Problems it causes:

How Pre-Emergent Works

Soil Temperature Trigger

Seeds germinate at 55°F (late March-early April). Pre-emergent must be applied BEFORE this, ideally when soil reaches 50°F.

Barrier Formation

Creates chemical barrier in soil surface. Seeds die on contact before emerging. Effective for 8-12 weeks.

Critical Timing

Too early (February) = product degrades. Too late (mid-April) = already germinated. Narrow window: early-mid March.

Prevention vs Post-Emergent Control

Prevention (March)

Cost: $50-$100 | Applications: 1 | Effectiveness: 90-95% | Result: Crabgrass-free lawn all summer

Post-Emergent (June-August)

Cost: $150-$400+ | Applications: 2-4 | Effectiveness: 60-80% | Result: Reduced but not eliminated, dead patches, seeds produced for next year

The economics are clear: Prevention costs less, works better, saves weekends.

Frequently Asked Questions

Can I apply pre-emergent myself?

DIY is possible but often fails due to timing errors, improper rates, or inadequate coverage. Consumer products provide only 6-8 weeks protection vs our commercial products' 10-12 weeks. We combine pre-emergent with spring fertilization in one application—saves time, ensures perfect timing.

What if I want to overseed this spring?

Pre-emergent prevents ALL seeds—including grass seed. We strongly recommend fall overseeding instead. Fall provides ideal conditions and allows full spring pre-emergent coverage. Spring seeding conflicts with crabgrass prevention.

When exactly should it be applied?

Early to mid-March in Howard County. We monitor actual soil temperatures (not just calendar dates) and schedule when soil approaches 50°F. Our 39 years of experience means we know exactly when to apply for maximum effectiveness.

What if I already see crabgrass?

Pre-emergent won't help—it only prevents germination. You'll need post-emergent control (more expensive, less effective). Best strategy: treat existing plants now to minimize seeds, then make pre-emergent your top priority next March.
