Pre-emergent For Northern VA Lawns

We're starting our pre-emergent application, and I'd like to take this opportunity to delve into what pre-emergent is and its importance for your lawn in Northern Virginia.

What Exactly is Pre-emergent?

Pre-emergent creates a barrier at the soil surface, disrupting the normal development of seeds. While some may believe it prevents germination, it actually stops new seedlings from establishing roots. As a result, seeds may germinate but will ultimately perish. This process is crucial, considering your lawn's soil contains tens of thousands of weed seeds at any given moment, brought in from various sources including neighbors who don't have a lawn service. These weeds are adept at spreading, making them invasive. A timely application of pre-emergent ensures these seeds don't evolve into ugly weeds.

Can I Put Down Grass Seed with Pre-emergent?

Applying pre-emergent means you cannot sow grass seed simultaneously, as it affects all seeds indiscriminately. Therefore, if you're planning spring seeding, omit the pre-emergent to allow your grass seeds to establish. At Simply Turf, we use a liquid pre-emergent, which offers the flexibility to treat specific areas while leaving others untreated for repairs without compromising the lawn's overall weed defense.

Optimal Timing for Pre-emergent Application

Weed and grass seeds begin to germinate when soil temperatures hit 50-55 degrees, usually around mid-April in Northern Virginia. However, it's best not to wait until then. Applying pre-emergent early ensures it integrates well with the soil's top layer, where it's most effective. Post-application rainfall helps with this integration. Be mindful of microclimates within your lawn that may encourage earlier weed growth, and plan your application accordingly.

Why Apply Pre-emergent Twice?

Our approach includes two spring applications—not for the sake of excess but for precision and longevity. The first application ensures even coverage, much like a base coat in painting, to prevent any "missed spots." A second application extends the barrier's effectiveness into summer, combatting weeds when the weed pressure it highest, the middle to end of summer.

Granular vs. Liquid Pre-emergent

We advocate for liquid pre-emergent due to its superior coverage and precision. Granular products, often combined with fertilizer, can leave gaps in protection. If you've noticed subpar weed control from such products, this coverage issue is likely the cause. Liquid application, conversely, ensures thorough, gap-free coverage.
