Why February Lawn Care Starts With Getting Pre-Emergent Timing Right

February in South Jersey is deceptive. The snow’s mostly gone, but your lawn still looks half-dead. Temperatures bounce between 25°F at night and 50°F during the day. Most homeowners figure there’s nothing to do until April.

That’s where they’re wrong.

Your February decisions determine whether you’ll be fighting crabgrass all summer or enjoying a thick, weed-free lawn. Soil temperatures are waking up. Weed seeds are getting ready to germinate. And if you wait until you see green grass to start thinking about lawn care, you’ve already missed your window.

We’re going to walk through exactly what needs to happen in February to set your lawn up right. This isn’t theoretical advice from a blog writer who’s never touched a spreader. We’ve been managing lawns across Gloucester County since 2005, and we know what works in our clay-heavy soils and unpredictable spring weather.

Why February Matters More Than You Think

Most people think of lawn care as starting in spring. But “spring” for your lawn starts way before it starts for you.

Crabgrass seeds begin germinating when soil temperatures hit 55°F for several consecutive days. In Franklinville, Williamstown, and Washington Township, that usually happens in late March or early April. But here’s the thing: pre-emergent herbicides need to be down before those seeds germinate. Once you see crabgrass sprouting, it’s too late for pre-emergent to work.

February is your planning month. It’s when you need to:

• Get your soil tested so you know what amendments you’ll need
• Schedule pre-emergent applications for the right window
• Assess winter damage and plan any necessary repairs
• Make sure your lawn is actually ready to respond when spring hits

Skip February prep, and you’re spending the entire growing season playing catch-up. We see it every year: homeowners calling in June asking why their lawn is full of weeds despite “doing everything right” in April and May.

The Pre-Emergent Window: Get This Right or Fight Weeds All Summer

Let’s get specific about pre-emergent timing because this is where most DIY lawn care goes sideways.

Pre-emergent herbicides work by creating a chemical barrier in the top layer of soil. When weed seeds try to germinate, they hit that barrier and die. But the barrier only works if it’s in place before germination starts.

For South Jersey lawns, here’s what you need to know:

The ideal application window is when forsythia bushes start blooming, usually mid to late March in our area. But you need to be ready to move earlier if we have a warm February. In 2024, we had three days in the low 60s during the third week of February, and soil temps spiked. Homeowners who waited until “the usual time” lost their pre-emergent window.

We monitor soil temperatures constantly starting in February. Once we see consistent readings above 50°F, we know we have about two weeks before the germination zone. That’s when applications need to happen across Monroe, Sicklerville, and the rest of our service area.

What Pre-Emergent Actually Controls

Pre-emergent isn’t just for crabgrass, though that’s what gets all the attention. A properly timed application also prevents:

• Annual bluegrass (poa annua), which germinates in fall but also has a spring germination window
• Goosegrass, which shows up in the heat of summer but germinates in spring
• Spurge, oxalis, and other broadleaf weeds that germinate early

One application in the right window can eliminate 85-90% of your summer weed pressure. Miss that window, and you’re looking at multiple post-emergent treatments all season long.

Pro tip: If you’re planning to overseed this spring, pre-emergent will prevent your grass seed from germinating too. You can’t do both at the same time. This is why fall is the better overseeding window in New Jersey. Spring pre-emergent timing and seeding just don’t work together.

February Lawn Assessment: What to Look For

While your grass is still dormant, take a walk around your property with a critical eye. This is the best time to spot issues that get hidden once everything greens up.

Winter damage patterns show up clearly in February. Look for:

• Vole tunnels and damage: Small raised ridges in the grass, especially near landscape beds or wooded edges. Voles stay active all winter under snow cover and can destroy significant turf areas.
• Salt damage along walkways and driveways: Brown or dead patches where deicing salt accumulated. These areas will need special attention come spring.
• Snow mold: Circular patches of matted, grayish grass. Common in areas where snow piled up for extended periods. Usually recovers on its own once things dry out, but severe cases might need treatment.
• Bare or thin spots: These could be from disease, grub damage, or just poor establishment. Flag these areas now. They’ll need extra attention during spring cleanup and possibly new seeding or sod installation.

In Blackwood and Glassboro, where we deal with heavier clay soils, February is also when you’ll see standing water or soggy areas that never quite dry out. These are drainage problems that need addressing. If water’s still sitting in your yard in February, imagine what it’ll be like during April rains.

Equipment Check and Soil Testing: The Boring Stuff That Actually Matters

If you handle your own lawn maintenance, February is when you should be servicing your mower, checking your spreader calibration, and generally making sure your equipment is ready to go.

We see a lot of homeowners lose the first few weeks of good mowing weather because their mower won’t start or their spreader isn’t distributing evenly. Get ahead of that now.

More importantly, get a soil test done in February. Your county extension office offers inexpensive testing, or you can use a commercial lab. You need to know:

• Soil pH (ideal range for most lawn grasses is 6.0-7.0)
• Phosphorus and potassium levels
• Organic matter content

South Jersey soils tend to be acidic and clay-heavy. Most lawns in Pitman and Atco benefit from lime applications every few years to raise pH. But you won’t know if you need lime, or how much, without testing.

Testing in February gives you time to apply any needed amendments before you put down fertilizer in spring. Lime takes months to fully adjust soil pH, so applying it in February or early March sets you up for better nutrient availability all season long.

What About Fertilizer in February?

Short answer: no.

Your grass is dormant. It’s not growing, so it’s not using nutrients. Applying fertilizer to dormant turf is wasteful and increases the risk of runoff into storm drains.

Early spring fertilization should wait until your grass is actively growing, usually mid to late April in our area. You’ll know it’s time when you need to mow for the second time.

The exception is if your soil test shows a severe deficiency in a nutrient that takes time to incorporate, like the lime situation we mentioned earlier. But standard nitrogen-based fertilizers? Wait until spring.

Planning Landscape Projects While the Ground is Bare

February is actually an ideal time to plan any landscape improvements or installations you’ve been thinking about.

With everything dormant and the ground bare, you can see your property’s bones. Drainage issues are obvious. Poorly placed plants are easy to spot. And you can envision how a new patio, walkway, or landscape bed would fit without mentally removing all the summer growth.

If you’re considering projects like a paver patio or retaining wall, or a full landscape redesign, February consultations give us time to design, plan, and get on the schedule for spring installation. Most landscape design and hardscaping work happens in April and May, which means those months book up fast. Starting the conversation in February puts you ahead of the rush.

We also handle a lot of drainage correction projects, including French drains, grading work, and drainage solutions for chronically wet areas. These are easier to install before everything starts growing, and they make a massive difference in lawn health once the growing season kicks in.

The Spring Cleanup Countdown

Spring cleanups typically happen in late March or early April, depending on weather. But February is when you should be thinking about what that cleanup needs to include.

A thorough spring cleanup and landscape maintenance involves:

• Removing leaves and debris that accumulated over winter
• Raking out dead grass and thatch
• Edging landscape beds
• Cutting back ornamental grasses and perennials that were left for winter interest
• Pruning dormant trees and shrubs before bud break

If you’re handling this yourself, start staging your supplies and schedule time for the work. If you’d rather have professionals handle it, get on the schedule now. Our spring cleanup crews book out weeks in advance.

Consider dethatching if you have significant thatch buildup. More than half an inch of spongy dead material between the soil and green grass is a sign you need it. Dethatching is stressful for the lawn, so it needs to happen early enough that the grass has time to recover before summer heat arrives. We typically handle dethatching in late March or early April, right before or during spring cleanup.

Setting Up Your Lawn Care Calendar

Here’s what a properly timed South Jersey lawn care calendar looks like from February through early spring:

February:

• Soil testing
• Equipment maintenance
• Planning landscape projects
• Monitoring soil temperatures

March:

• Pre-emergent application (mid to late March, or earlier if soil temps rise)
• Lime application (if soil test recommends)
• Spring cleanup begins (late March)

Early April:

• Spring cleanup continues
• First mowing of the season
• First fertilization (after second mowing)

Late April/Early May:

• Overseeding thin or bare areas (if you skipped pre-emergent)
• Weed control treatments as needed
• Monitor for early-season lawn diseases

The exact timing shifts based on actual weather, but this framework keeps you ahead of problems instead of reacting to them.

Ready to Get Your South Jersey Lawn on the Right Schedule?
