1. Don’t Fertilize Your Lawn During the Winter

This is the most common—and most costly—mistake.

Why?

Once warm-season grasses go dormant, they stop absorbing nutrients. That means:

• The fertilizer sits on the surface and washes away with winter rains

• You waste money on nutrients the grass can’t use

• Runoff can carry fertilizer into storm drains and streams

• Forcing growth during dormancy can actually weaken the turf

Applying nitrogen when your lawn isn’t actively growing can also feed the wrong things, like winter weeds (hello, henbit and Poa annua). Instead, save fertilization for late spring through summer, when your lawn begins to grow again after waking up.

2. Don’t Scalp or Cut Your Lawn Too Short

Scalping in winter leaves the crown exposed to freezing temperatures and increases the risk of winter die-out.

Instead, keep the last couple of fall cuts slightly taller so the grass has enough insulation to withstand cold snaps.

3. Don’t Water Unless Absolutely Needed

Most Tulsa winters receive sufficient moisture through rainfall. Overwatering during dormancy can lead to:

• Root rot

• Disease development

• Compacted soil (especially in clay-heavy areas)

Only water if the lawn experiences extended dry spells AND temps rise above freezing.

4. Don’t Let Leaves Sit All Winter

Allowing leaves to pile up is an invitation for fungus and smothered turf.

Leaves left on dormant grass can:

• Trap moisture

• Encourage mold

• Block sunlight

• Slow spring green-up

Mulch or rake leaves as needed.

5. Don’t Disturb Frozen or Frost-Covered Grass

Walking or driving on frozen turf can crush the brittle blades and damage the crown.

You may not see the results right away, but in spring, these areas often come back thin or patchy.

6. Don’t Skip Winter Weed Prevention

While your grass sleeps, winter weeds wake up.

These include:

• Annual bluegrass (Poa annua)

• Chickweed

• Henbit

• Rescuegrass

A pre-emergent applied in the fall, plus spot-treating during the season, keeps these troublemakers under control and prevents them from stealing nutrients in the spring.

7. Don’t Put Off Spring Prep

Winter is a great time to get ahead.

What you should do instead:

• Schedule a spring pre-emergent

• Plan your fertilization schedule for warm-season grasses

• Clean and service equipment

• Consider soil testing if your lawn struggled last year

By the time spring arrives in Tulsa, having a plan in place makes all the difference.

FAQ: Winter Lawn Care in Tulsa

Can winter fertilization harm my lawn?

Yes. Applying nitrogen too early can encourage weak, off-season growth, increase disease risk, feed winter weeds, and stress the turf as it heads into spring.

Why does my lawn look dead in winter?

Warm-season grasses naturally turn brown and go dormant during cold weather. This is normal and doesn’t mean your grass is dying—just conserving energy until temperatures rise.

Is it okay to walk on frozen or frost-covered grass?

Avoid it if possible. Walking on frozen turf can break the brittle blades and damage the crown, resulting in thin or bare spots in the spring.
