Best Time to Seed Your Lawn in North Texas (Sherman Area Guide)

When to Seed Your Lawn in Sherman, TX: The Complete North Texas Guide

If you live in Sherman, Texas, you already know North Texas lawns can be unpredictable. One year they’re thick and green; the next, they’re thin, patchy, and overrun with weeds.

If you’re wondering when to seed your lawn, here is the short answer:

The best time to seed most North Texas lawns is late spring to early summer (April–June) for warm-season grasses.

In this guide, we’ll break down the specifics of Sherman lawn care, from soil temperatures to the common "Northern lawn" myths that lead to failed yards.

Why Timing Matters in North Texas

If you’ve moved to Sherman from the Midwest or Northeast, lawn timing can feel backward. Northern lawns use cool-season grasses (Fescue/Bluegrass) that love fall seeding.

In Grayson County, we use warm-season grasses:

• Bermuda (Most common for seeding)
• Zoysia (Great for durability)
• St. Augustine (Usually installed as sod)

Soil Temperature: The Real Metric

Air temperature is a liar. For successful germination in Sherman, your soil temperature must be consistently above 65°F. This typically happens between late April and early May.

If you seed too early:

• Seeds may rot in cold, damp soil.
• Weeds will establish faster than your grass.
• Germination will be patchy and uneven.

The Summer Advantage vs. Fall Dormancy

Unlike Northern turf, our grass thrives in the heat. Late spring provides the perfect combination of long daylight hours and consistent soil warmth, allowing seedlings to establish deep roots before winter.

The Danger of Fall Seeding

In North Texas, warm-season lawns go dormant when temperatures dip into the 50s. If you seed in September or October:

1. The grass won't have time to mature.
2. Young roots will likely die during the first freeze.
3. Your spring "green-up" will be thin and weak.

Overcoming the Sherman Clay Soil Challenge

Sherman lawns are notorious for heavy clay soil. Clay holds water too tightly and compacts easily, leading to shallow root systems.

Pro Tip: For the best results, perform core aeration before seeding. This opens up the soil, allowing the seed to make direct contact with the earth rather than sitting on top of a hard clay crust.

Step-by-Step: How to Seed Your Lawn Successfully

1. Control Weeds First: You cannot seed effectively into an active weed infestation.
2. Prep the Ground: Mow low and remove debris.
3. Apply Seed Evenly: Use a broadcast spreader for uniform coverage.
4. Water Consistently: Keep the soil moist (but not flooded) with light, frequent watering.
5. Fertilize: Use a starter fertilizer to encourage rapid root development.
