How to Prepare Your Lawn for Spring

Late winter is the perfect time to start thinking about your spring lawn game plan. Whether you’re dealing with matted-down grass, leftover leaves, or mystery bare spots, a little prep now pays off big once growing season kicks in.

Here’s a practical, week-by-week approach to getting your yard ready.

Start With a Good Cleanup

Before you do anything else, get the debris off your lawn. Leaves, sticks, and anything that’s been sitting all winter traps moisture and blocks sunlight — both of which encourage fungal growth.

Rake lightly or use a leaf vacuum to clear things out. A solid leaf rake like the Bully Tools 24-Inch Leaf Rake makes quick work of winter debris. You’re not trying to dethatch yet — just remove the surface layer of winter mess so the grass can breathe.

While you’re out there, take note of any areas that look thin, bare, or waterlogged. You’ll address those soon.

Test Your Soil Early

This is the step most people skip, and it’s the one that makes the biggest difference. A simple soil test — something like the MySoil Soil Test Kit — tells you your pH and nutrient levels so you’re not guessing when it comes to fertilizer and amendments.

Most lawn grasses thrive in a pH range of 6.0–7.0. If your soil is too acidic, you’ll need lime. Too alkaline? Sulfur. Either way, you can’t know without testing.

Address Bare Spots and Thin Areas

Once temperatures are consistently above 50°F (for cool-season grasses), it’s time to overseed bare and thin areas. Scratch up the soil lightly with a rake, spread seed, and keep it moist until germination.

If you’ve got just a few patches, a lawn patch repair product with seed, mulch, and fertilizer built in makes the job easy.

For larger areas or a full overseed, our overseeding guide walks you through timing, seed rates, and watering schedules.

Hold Off on the First Mow

One of the most common spring mistakes is mowing too early or cutting too short. Wait until your grass is actively growing and reaches about 3–3.5 inches before that first cut. Then take off no more than one-third of the blade height.

Make sure your mower blades are sharp — dull blades tear the grass and leave it vulnerable to disease. A clean cut makes a real difference in how quickly your lawn greens up.

Apply Pre-Emergent at the Right Time

Timing your pre-emergent herbicide is everything. Apply too early and it breaks down before crabgrass germinates. Too late and the weeds are already growing.

The general rule: apply when soil temperatures hit 55°F for a few consecutive days. In most of the US, that’s roughly mid-March through mid-April, depending on your region. For a full breakdown of timing by grass type and climate zone — including early, mid, and late spring task windows — see our guide on when to start spring lawn care activities.

Feed Your Lawn — But Don’t Overdo It

Your lawn is hungry after winter, but a heavy dose of nitrogen too early can do more harm than good. If you’re using a synthetic fertilizer, wait until your grass has been actively growing for 2–3 weeks. A light application of a balanced spring fertilizer is plenty to get things moving.

If you prefer the organic route, our organic fertilizer roundup has options that feed the soil biology along with the grass.

Use a quality spreader like the Scotts Turf Builder EdgeGuard for even coverage — hand-tossing leads to streaks and burns.

Check Your Irrigation Setup

Before you need it, turn on your sprinkler system and check every zone. Look for broken heads, misaligned spray patterns, and dry spots. A quick inspection now saves you from discovering problems in June when your lawn is already stressed.

If you’re running a manual setup, our sprinkler and smart irrigation guide can help you upgrade to something more efficient.

Make a Season-Long Plan

Spring prep isn’t just about the first few weeks — it sets the tone for the whole year. Here’s a rough timeline:

Having a plan keeps you from doing too much at once or forgetting key steps. Our spring lawn care checklist is a printable version you can stick on the fridge.
