Jumpstart Your Lawn’s Spring Recovery this March

This March lawn care checklist will help Knoxville homeowners jumpstart their lawn’s spring recovery with a few smart steps early in the season. Early spring is one of the most important windows to get ahead of weeds, encourage fresh growth, and prevent costly issues later in the season.

Whether you’re caring for fescue or prepping Bermuda for warmer days ahead, here’s a simple checklist to help your lawn recover and thrive this spring.

1. Apply Any Remaining Pre-Emergent

If you didn’t apply pre-emergent herbicide in February, there’s still time—but not much. According to the UT Extension office, crabgrass and other common weeds begin germinating once soil temperatures hit about 55°F.

Act fast: Early March is your final window to stop spring weeds before they start. Pre-emergents are especially helpful in Knoxville’s unpredictable weather patterns where warm days can sneak up quickly. Checking off your March lawn care checklist now sets you up for easier mowing and fewer weeds in April.

Need help? We offer professional pre-emergent applications that take the guesswork out of timing.

2. Start Weekly Mowing for Cool-Season Lawns

If your lawn is tall, matted, or looking a bit ragged after winter, it’s time for the first mow. For cool-season grasses like fescue:

Set mower height to 3–3.5 inches
Use a sharp blade to avoid tearing grass
Mow when the lawn is dry to avoid ruts or clumping

Begin weekly mowing once growth picks up to encourage thickness and reduce weeds. Avoid cutting too low—scalping weakens turf and invites problems.

3. Check for Lingering Winter Weeds or Disease

Scan your lawn for patches of early weeds like chickweed, henbit, or wild onion. These can overwinter and spread quickly as temperatures rise.

Also watch for signs of fungal disease such as:

Gray or brown patches
Snow mold (often visible in shaded, wet areas)
Thatch buildup or overly compacted soil

Spot-treat weeds or consult a lawn professional if disease persists beyond mild cleanup.

4. Plan Ahead for Aeration and Warm-Season Lawn Prep

March is the perfect time to schedule aeration for April or May, especially if you have compacted soil or a warm-season lawn like Bermuda or zoysia. These grasses benefit most from aeration once they’re actively growing.

If your cool-season lawn needs aeration, hold off until fall, which is the ideal window for that variety.

Planning ahead now ensures you reserve a spot before schedules fill up.

5. Edge Beds, Refresh Mulch, and Plan Flower Installations

While you’re focused on the lawn, don’t forget curb appeal. Crisp bed edges and fresh mulch instantly boost the look of your property and help retain moisture before summer heat arrives.

Want seasonal flowers or pine straw installed in time for April? Early planning means your yard will be camera-ready by Easter or spring gatherings.
