Patchy Lawn Repair: Spring Fertilization and Pre-Emergent Fixes

Is your lawn looking a little worse for wear after winter? If you’re dealing with bare spots, thin grass, or uneven growth, you’re not alone. Many homeowners struggle with patchy lawn repair in spring, but the good news is that the right combination of spring fertilization and pre-emergent weed control can set your yard up for a season of lush, healthy growth.

Why Do Lawns Get Patchy After Winter?

Before diving into solutions, let’s talk about why your lawn struggles after winter. Common culprits include:
✅ Winter stress – Cold temperatures and frost weakens grass roots.
✅ Compacted soil – Heavy snow, ice, or foot traffic presses down the soil, making it hard for roots to grow. Did your play outside on the snow days we had this year? The snow definitely impacted lawn health.
✅ Thatch buildup – A thick layer of dead grass will block new growth.
✅ Weed competition – Early-sprouting weeds steal nutrients before grass has a chance to thrive.

The key to repairing a thin lawn in spring is to feed your grass properly while preventing weeds from taking over.

Go over our Weed and Feed Schedule, so you know when to apply weed control and lawn fertilization products.

Step 1: Start with Spring Fertilization

Don’t worry if your lawn is looking a little rough right now. There’s an easy fix. Fertilizing in early spring kickstarts growth and strengthens your grass. But not all fertilizers are created equal. Here’s what to look for:

🔹 Choose a balanced fertilizer – A mix of nitrogen, phosphorus, and potassium will promote strong roots and vibrant green blades.

🔹 Slow-release formulas work best – These provide steady nutrients over time instead of a quick surge that fades fast.

🔹 Timing matters – Apply fertilizer when soil temperatures reach 55°F to 60°F (typically in early to mid-spring). This is important since we are having a longer winter than usual in North Texas.

A properly fertilized lawn grows thicker, making it harder for weeds to sneak in.

Step 2: Apply a Pre-Emergent to Block Weeds

If you want to prevent weeds like crabgrass, dandelions, and clover, a pre-emergent herbicide is your best friend.

✔ What is a pre-emergent? It’s a weed preventer that stops seeds from sprouting, keeping your lawn weed-free before problems start. Read our article explaining what pre-emergents are and when to apply them.

✔ When to apply? Right before soil temperatures hit 55°F—usually when forsythia bushes start blooming in early spring.

Hurley (2016) The forsythia (Forsythia spp.) plant can be used to time preemergence herbicide application. Make pre-emergence applications when forsythia is in full bloom (their yellow flowers are usually among the first plants to bloom).

✔ How to apply? Spread evenly across your lawn and water it in to activate the formula.

🔹 Important Tip: If you plan to overseed thin areas, avoid pre-emergent in those spots, as it will also prevent grass seeds from germinating.

Step 3: Fill in Bare Patches with Overseeding

If your lawn has thin or bald spots, overseeding is the way to go. Here’s how to do it right:

1️⃣ Rake and loosen the soil in patchy areas to help seeds settle.
2️⃣ Choose a high-quality grass seed that matches your existing turf.
3️⃣ Spread the seed evenly and lightly cover it with soil.
4️⃣ Water daily until new grass is established.

🌱 Pro Tip: If you used pre-emergent on your lawn, be sure to overseed areas that were left untreated!

Step 4: Quick Fix – Patch Bare Spots with Sod

If you need a fast solution for patchy lawn repair, replacing bare spots with sod is the quickest way to achieve an instant green lawn. Unlike seeding, which takes weeks to establish, sod gives you immediate coverage.

Here’s how to patch lawn spots with sod:

✅ Cut out the dead grass – Use a shovel to remove the damaged area and loosen the soil underneath.
✅ Measure and cut sod pieces – Match the size of the bare spot to a fresh piece of sod.
✅ Lay the sod down – Press it firmly into place, ensuring there are no air pockets.
✅ Water thoroughly – Sod needs consistent watering for the first 2–3 weeks to help roots establish.

🔹 Pro Tip: If you want the sod to blend seamlessly, make sure you’re using the same grass type as the rest of your lawn!
