Getting Your Missouri Lawn Ready for Spring

Spring in mid-Missouri can fool you. A warm week in February will have the forsythia blooming and make you want to get out and start working the yard — but a hard freeze in March is more common than not. Knowing when to act and when to wait is half the battle.

When Does Spring Actually Start for Your Lawn?

For fescue lawns (the most common turf grass in our area), soil temperature matters more than calendar date. You want soil temps consistently above 50°F before you apply fertilizer or seed. In Clover Ridge, that usually falls somewhere between late March and mid-April, depending on the year.

You can buy a soil thermometer for a few dollars — it’s worth it. Or check the University of Missouri Extension’s soil temperature monitoring map online.

Step 1: Clean Up and Assess

Before anything else, walk the yard and take stock:

• Rake out dead material. Winter matted grass can create a thatch layer that blocks water and fertilizer. A light dethatching or vigorous raking helps.
• Look for bare spots. Note where you’ll need to overseed. South-facing slopes and high-traffic areas are usually the first to thin out.
• Check for grubs. If you had brown patches last summer that didn’t green up, dig in a few spots. White grubs in the soil may have been the cause.

Step 2: Don’t Fertilize Too Early

This is the most common mistake we see. Applying nitrogen before the grass is actively growing just feeds the weeds — crabgrass and chickweed will take it right up.

Wait until the lawn has broken dormancy and you’ve mowed it at least once before applying a spring fertilizer. A 32-0-8 or 28-0-6 formula works well for fescue in early spring.

Tip: If you’re planning to apply a pre-emergent crabgrass preventer, do that before you see dandelions blooming. Pre-emergent needs to be down before soil temps hit 55°F — about the time forsythia blooms are dropping. Don’t overseed and apply pre-emergent at the same time — pre-emergent will prevent your grass seed from germinating too.

Step 3: Overseeding Bare and Thin Spots

Spring overseeding works, but fall is honestly better for fescue in Missouri. If you have bare spots that need attention now:

1. Scratch up the soil surface with a rake or hard-tine detatcher.
2. Apply a quality tall fescue blend — we carry Missouri-adapted varieties that handle our summer heat better than budget seed mixes.
3. Apply starter fertilizer (high phosphorus, like a 12-24-8).
4. Keep the seed bed moist until germination — usually 10–14 days.

Expect new seeding to look thin through its first summer. It will thicken up by fall.

Step 4: Broadleaf Weed Control

Dandelions, clover, ground ivy, and wild violet are the most common spring weeds we see around here. A broadleaf herbicide containing 2,4-D, MCPP, and dicamba (sold as Trimec or similar) is effective on most of them.

Apply when weeds are actively growing and temperatures are between 60°F and 85°F. Don’t spray when it’s windy or rain is expected within 24 hours.

Wait to spray if you’ve recently seeded — most herbicides need 6–8 weeks after germination before they’re safe to use.

What to Pick Up Before You Start

Here’s a basic spring lawn kit to put together:

• Soil thermometer
• Pre-emergent crabgrass preventer (early spring)
• Starter fertilizer (for bare spots)
• Spring lawn fertilizer (after first mow)
• Tall fescue grass seed (Missouri blend)
• Broadleaf herbicide (mid to late spring)
