Lawn Care Basics for Missouri Lawns

GREENERLAWN - Article - Lawn Care Basics

How do I get a healthy lawn here in Missouri?

Missouri lawns face unique challenges because of our weather and our clay-heavy soil. The key is giving your grass what it needs to thrive through every season: proper aeration, overseeding when needed, mowing at the right height, watering smart, and addressing bare spots early.

What kind of grass works best in Jefferson County and St. Louis?

Most homes in our area have cool-season grasses like tall fescue or Kentucky bluegrass. These types do well in our climate, especially with a strong root system supported by regular core aeration and proper overseeding.

How often should I aerate my lawn?

For most Jefferson County and St. Louis lawns, once a year is ideal. Fall is the best time because it sets your lawn up for success the following spring. If you’ve never aerated before, or if your soil is very compacted, you may benefit from two rounds your first year.

Pro tip: Aeration and overseeding together give the best results. GREENERLAWN offers a combined service we call The Works that pairs them for maximum lawn improvement.

When should I overseed my lawn?

Fall is the ideal time to overseed cool-season grasses in Missouri. Overseeding after core aeration allows new seed to take hold deep in the soil, giving your lawn better density and fewer bare patches. We recommend this for more well-established lawns.

Spring overseeding may also be necessary to repair lawns and bare patches, but fall gives the seed the best chance to establish before summer stress.

How do I water my lawn properly?

Most local lawns need about 1 to 1.5 inches of water per week, either from rainfall or watering. It’s better to water deeply and less often than to water lightly every day. Early morning is the best time to water to prevent disease.

After overseeding, you’ll need to keep the top layer of soil consistently moist until the new seed germinates. We provide watering instructions for all of our aeration and overseeding clients.

What mowing height is best for Missouri lawns?

  • Tall fescue: 4 inches or higher

  • Kentucky bluegrass: 3 to 3.5 inches

Never cut more than one-third of the grass blade at a time. Taller grass helps shade out weeds and promotes deeper roots.

Why does my lawn have bare spots?

Bare spots often develop from compaction, drought stress, pests, or poor soil. If your lawn has visible bare areas, simple overseeding might not be enough. GREENERLAWN offers a targeted Bare Spot Repair service where we properly prep the soil, address underlying problems, and reseed for lasting results.

When is the best time to start lawn care in Jefferson County?

Fall is the perfect window for aeration and overseeding. It prepares your lawn to emerge stronger in the spring. If you are dealing with bare spots or compacted soil, the sooner you address it, the better. For problematic lawns that need more repair, we will also provide our services in the Spring.
