SHREVEPORT, La. – As summer fades, Shreveport homeowners should turn their attention to the coming winter weed threat. Aiken’s Nursery and Landscaping says cooler soil temperatures—especially once they dip below 70°F—signal that winter weeds such as poa annua and chickweed are preparing to sprout.
Why Labor Day Is the Ideal Time
According to the nursery’s specialists, applying a fall pre‑emergent during the Labor Day weekend creates a protective barrier in the soil just as weed seeds begin to awaken. The product must be watered in within 24 hours, allowing the granules to move a half‑inch deep and block germination.
How to Apply Correctly
First, select a spreader and consult the manufacturer’s label for the recommended spreader setting. Pre‑emergent products are typically applied at a heavier rate than weed‑and‑feed mixes, so adjusting the spreader is essential. After broadcasting the granules, water the lawn thoroughly—either with irrigation or a hand‑held hose if rain is not in the forecast.
Make It Part of a Year‑Round Routine
Aiken’s recommends a three‑time annual schedule: January, May, and around Labor Day. The January treatment targets summer weeds like crabgrass, while the late‑summer application focuses on winter‑season invaders. Consistency is key; a single application will not keep a lawn weed‑free for the entire year.
Why Prevention Beats Post‑Emergent Sprays
Warm‑season grasses such as St. Augustine can be especially vulnerable. Selective post‑emergent herbicides often struggle to differentiate between unwanted grassy weeds and desirable turf, risking damage to the lawn itself. By preventing weeds from germinating in the first place, homeowners avoid the need for harsher chemicals later on.
Product Options
Products like Dimension and other pre‑emergent herbicides are widely available at local garden centers. When used as part of a seasonal weed‑control program, they provide a cost‑effective, low‑maintenance solution for families who want a tidy, healthy lawn throughout the colder months.
Bottom Line for Shreveport Residents
Labor Day weekend offers a practical window to get ahead of winter weeds. Apply a pre‑emergent, water it in promptly, and stick to the recommended three‑year schedule for the best results. With a little foresight now, Shreveport lawns can stay lush and weed‑free all winter long.
