Introduction

Creating a lush, green lawn is a top priority for many homeowners—but achieving that healthy turf isn’t as simple as tossing down seed or rolling out sod. At Sandy Creek Landscaping, we’ve seen the good, the bad, and the costly when it comes to DIY lawn installations. While do-it-yourself sod or seeding can be tempting, mistakes in soil prep, grass selection, timing, and watering often lead to spotty, unhealthy lawns and frustrating do-overs.

In this blog post, we’ll explore the do’s and don’ts of lawn installation, and help you decide when it’s time to call in the pros. Whether you live in Oakville, Ballwin, Kirkwood, Mehlville, Affton, Manchester, or Lemay, this guide is designed for homeowners throughout St. Louis County, MO.

The Do's of DIY Grass Seeding & Sod Installation

✅ DO test your soil

Understanding your soil’s pH and nutrient levels is essential before planting. Without proper soil structure and nutrients, even premium seed or sod won’t take root properly.

✅ DO choose the right grass variety

Not all grass is created equal. Select seed blends or sod types that are specifically adapted to the Missouri climate, your sun/shade balance, and soil type.

✅ DO properly prep your yard

Remove all weeds, debris, and rocks. Till or aerate the soil, level the ground, and ensure good drainage before any installation.

✅ DO install at the right time

In St. Louis County, the best times to plant seed are early fall and spring, while sod can be laid throughout much of the growing season with proper care.

✅ DO water consistently

Sod and grass seed need frequent, gentle watering until roots are established. Water lightly and often, and adjust based on weather conditions.

The Don’ts of DIY Lawn Installation

❌ DON’T skip soil prep

Failing to properly prepare the soil leads to uneven growth, poor drainage, compaction, and weak root systems.

❌ DON’T install sod on top of existing grass

Sod must make full contact with the soil underneath. Leaving old grass or weeds in place will kill the new sod or lead to disease.

❌ DON’T use the wrong seed mix

Seed blends not suited for Missouri conditions—or for your property’s specific sun and moisture levels—will struggle or fail.

❌ DON’T over- or under-water

Too much water causes rot and disease, while too little dries out seed or prevents sod roots from establishing. It’s a delicate balance.

❌ DON’T mow too early

For seed, wait until the new grass reaches at least 3 to 4 inches tall before mowing. For sod, allow 2–3 weeks for root establishment.
