Fertilizing your lawn in Texas shouldn’t feel like guesswork. But with so many options, it’s easy to feel overwhelmed.

Big numbers. Fancy labels. Granular vs. liquid. Slow-release vs. fast.

So here’s the real question:
What type of fertilizer actually works best for Texas grass?

Let’s break it down.

Know Your Grass First

In Texas, you’re probably working with one of these:

• Bermuda – Tough, sun-loving, and fast-growing

• Zoysia – Dense, slower-growing, handles light shade

• St. Augustine – Broad-bladed, thrives in shady spots, likes moisture

Each of these grasses needs fertilizer to thrive—but not all fertilizers are the same.

Understand the Numbers on the Bag

Every fertilizer label has three numbers. Like 15-5-10 or 28-0-3.

Here’s what they mean:

• N (Nitrogen) – Makes your grass green and lush

• P (Phosphorus) – Builds strong roots

• K (Potassium) – Boosts stress and drought resistance

Most established Texas lawns need a high-nitrogen fertilizer. That’s what helps with that rich, healthy green-up.

Best Fertilizers for Texas Lawns

Let’s go through the top options—and when to use them.

1. Slow-Release Nitrogen Fertilizer

Use for: Regular feeding in spring and early summer

This is the go-to for most lawns in Texas. It feeds gradually over time. That means fewer spikes in growth, less mowing, and deeper roots. It also reduces the risk of burning your lawn.

Look for labels like “slow-release” or “controlled-release.”

2. Starter Fertilizer

Use for: New sod, seed, or after aeration

These are high in phosphorus to help roots develop quickly. You’ll usually see ratios like 12-24-8. We often use these during sod installation jobs.

Great for kickstarting growth—but not something you use regularly.

3. Organic Fertilizer

Use for: Long-term soil health

Organic blends (like Milorganite or compost-based options) feed the lawn and build healthier soil. They’re slower acting but great if your yard has clay-heavy soil or needs more organic matter.

Bonus: they’re kid- and pet-safe.

Liquid vs. Granular: Which One Should You Use?

• Granular fertilizer is easy to spread and sticks around longer.

• Liquid fertilizer works faster but needs more frequent applications.

If you’re doing it yourself, go granular. It’s easier to manage. If you’re hiring a pro, they’ll know what’s best for your lawn’s needs.

When to Apply Fertilizer in Texas

Timing matters just as much as the product. Here’s a rough guide:

• Early spring: Use a balanced, slow-release blend

• Late spring to early summer: Apply a high-nitrogen fertilizer

• Fall: Switch to something with more potassium to prep for winter

• Mid-summer: Be careful—too much fertilizer in the heat can burn your lawn
