Best Time to Fertilize Lawns in North Texas

Best Time to Fertilize Lawns in North Texas (Sherman, TX Guide)

Fertilizing your lawn isn’t about picking a random weekend and spreading product. In North Texas—and especially in Sherman—timing matters more than the fertilizer itself. Lawns respond very differently depending on soil temperature, grass growth cycles, rainfall, and heat stress.

Many homeowners fertilize too early, too late, or too aggressively, which leads to thin grass, weed outbreaks, and wasted money. This guide explains exactly when to fertilize lawns in North Texas and how Grayson County’s unique conditions affect your results.

The Sherman Seasonal Fertilization Calendar

To maintain a healthy lawn in North Texas, you must align your treatments with the natural growth of warm-season grasses (Bermuda and Zoysia).

1. Early Spring (Late March – Early April)

• The Goal: Wake up the roots without forcing a "growth explosion."
• Why Timing Matters: Fertilizing before the soil hits 65°F is a waste; the grass is still dormant and won't absorb the nutrients, but the weeds will!

2. Late Spring (May – June)

• The Goal: Build turf density.
• Strategy: This is your primary "feeding" window. High-quality nitrogen helps the grass spread, which naturally crowds out summer weeds.

3. Summer (July – August)

• The Goal: Survival, not growth.
• Strategy: Less is more. Using a heavy nitrogen fertilizer in 100°F Sherman heat can actually "burn" the grass or stress the roots. Switch to slow-release maintenance blends.

4. Fall (September – October)

• The Goal: Winter preparation and root strength.
• Strategy: Often called a "Winterizer" treatment, this is arguably the most important application for ensuring your lawn returns green next spring.

Why Timing Beats Product Choice

Homeowners often obsess over the brand of fertilizer, but when it’s applied is the true secret to success.

• Avoid the "Weed Feed": If you fertilize in February, you aren't feeding your grass; you’re feeding the Henbit and Chickweed that thrive in cool weather.
• Clay Soil Factor: Sherman’s heavy clay soil holds nutrients longer than sandy soil. If you apply a second round too soon, you risk nutrient runoff or chemical buildup that can damage soil biology.

FAQ: North Texas Fertilization

When is it too late to fertilize in the fall?In Sherman, you should aim to have your final fertilizer down before the first frost—usually by late October. Fertilizing once the grass has gone dormant (brown) is ineffective.

Should I water my lawn immediately after fertilizing?Yes. In North Texas, the sun is intense. Leaving fertilizer granules on top of the grass can cause "foliar burn." Watering helps move the nutrients into the clay soil where the roots can reach them.

Can I fertilize and apply weed control on the same day?Yes, but they should be targeted. A professional program coordinates these so the fertilizer feeds the grass while the weed control targets the invaders.
