What to do this fall
- 1
Core aerate
Core aeration relieves the compaction that builds up from Shreveport’s summer heat and heavy use. Punch 2–3 inch plugs of soil to create channels for water, air, and fertilizer to reach the root zone. Aerate in September while Bermuda Grass still has 4–6 weeks of active growth before the first frost around December 1. Always overseed immediately after aeration for best seed-to-soil contact and germination rates.

Overseed
Fall overseeding in Shreveport serves two purposes: thickening Bermuda Grass stands while soil is still above 65°F, and overseeding with annual ryegrass in October–November for winter green color while warm-season grass is dormant. For Bermuda thickening, overseed in September while growth is still active. For winter color, apply annual ryegrass at 8–10 lbs per 1,000 sq ft once overnight temperatures drop below 65°F. Mow short before overseeding to reduce shade competition on new seedlings.

Apply fall fertilizer (high potassium)
For Bermuda Grass and other warm-season grasses in Shreveport, apply a potassium-heavy formula 4–6 weeks before first frost around December 1. Potassium strengthens cell walls and improves cold hardiness, helping warm-season grass survive winter dormancy. Avoid high-nitrogen fertilizers after 6 weeks before frost — late nitrogen pushes soft new growth that frost damages easily. A winterizer blend with a 1-0-2 or 1-0-3 N-P-K ratio is ideal.

Rake leaves regularly
Fallen leaves left on the lawn for more than 2–3 days block sunlight and trap moisture, creating ideal conditions for fungal disease and winter kill in Shreveport. The most efficient approach: mulch-mow leaves with a sharp blade rather than raking. Shredded leaf particles smaller than a dime decompose rapidly and return organic matter to soil. Only bag if leaf volume is more than one full layer covering the grass. This is especially important for Bermuda Grass, which can develop patch disease under matted debris.
- 5
Final mow before dormancy
Time your final mow in Shreveport to occur approximately 1–2 weeks before first frost around December 1. Cut Bermuda Grass to 1.5–2 inches (Bermuda) or 2–2.5 inches (Zoysia/St. Augustine) for the final fall mow. This removes the brown tips that accumulate as warm-season grass approaches dormancy. Do not mow after the grass has gone fully dormant — mowing dormant turf tears the crowns rather than cutting blade tissue.

Signs Your Lawn Needs Attention This Fall
Lawn not recovering from summer stress
If brown patches persist into September, the grass may be dead, not dormant. Overseed those areas now.
Heavy thatch buildup over 0.5 inches
Fall is the best time to dethatch and aerate. Cool-season grasses recover quickly in autumn weather.
Bare patches that need filling before winter
Overseeding in September-October gives new grass 6-8 weeks to establish roots before first frost.
Broadleaf weeds taking hold in thin turf
Dandelions and clover spread aggressively in fall. Apply broadleaf herbicide while weeds are actively growing.
Soil compaction from summer activity
Kids, pets, and mowing compact soil over summer. Core aeration in fall relieves this and improves root growth.

Frequently Asked Questions
When should I aerate my lawn in Shreveport?
The best time to aerate in Shreveport is September through October, when cool-season grasses are actively growing and can recover quickly.
When should I stop mowing for winter in Shreveport?
In Shreveport, continue mowing until your grass stops growing, usually by late November. Lower your blade slightly for the final cut to reduce matting and disease risk over winter.
When should I do my last mow in Shreveport?
Plan your final mow approximately 1–2 weeks before the first expected cold snap in Shreveport. Mow slightly lower than normal on the final cut. Do not mow after grass has gone fully dormant — mowing dormant turf damages crowns.
When is the best time to overseed in Shreveport?
In Shreveport, the best overseeding window is typically September to mid-October — about 3–7 weeks before the first cold snap. For warm-season lawns like Bermuda and Zoysia, pair overseeding with core aeration for best seed-to-soil contact. You can also overseed with annual ryegrass in October–November for winter green color. New seed needs 4–6 weeks to establish roots.
Is fall fertilizer necessary in Shreveport if my lawn goes dormant?
Yes — a potassium-rich fall fertilizer builds root reserves that directly improve spring recovery speed and green-up, even though the lawn looks dormant above ground. Use a low-nitrogen, high-potassium formula (e.g. 5-0-20 or 10-0-25) to strengthen roots without pushing tender new growth. Apply approximately 5–6 weeks before dormancy begins in Shreveport.
