When To Plant Grass In Florida

If you’re wondering when to plant grass in Florida, timing is everything for a successful lawn. The state’s unique climate means you can’t just seed any time of year and expect good results. Getting the timing right is the single most important step you can take.

Plant at the wrong time, and you’ll waste money on seed that struggles to sprout or gets overtaken by weeds. The good news is that Florida’s long growing season gives you two excellent windows to work with. This guide will walk you through the optimal schedule for your specific grass type and region.

Florida is divided into three main climate zones: North, Central, and South. Each has its own best planting times. The general rule is to plant during the rainy season, when nature helps with irrigation, and when temperatures are warm but not extreme.

For most of Florida, the primary seeding season is late spring through early summer. A secondary window exists in early fall for some grasses. Let’s break it down by region.

North Florida Planting Schedule

North Florida experiences cooler winters. The best grasses here are warm-season types that can handle a occasional frost.

Best Time: April through July
Optimal Soil Temp: 65°F and rising at the 4-inch depth
Key Grass Types: Bermuda, Zoysia, Centipede, St. Augustine (usually sodded, not seeded)
Fall Option: You can plant in very early September, but any later risks winter damage to young grass.

Central Florida Planting Schedule

This region has the most flexibility due to its long, consistent warmth.

Best Time: March through July
Optimal Soil Temp: 70°F or higher
Key Grass Types: All warm-season grasses: St. Augustine, Bermuda, Zoysia, Bahia, Centipede
Fall Option: Early fall seeding is possible but less reliable than spring. Aim for before mid-September.

South Florida Planting Schedule

South Florida’s tropical climate allows for an even longer planting period.

Best Time: February through September
Optimal Soil Temp: Consistently above 70°F
Key Grass Types: St. Augustine, Bermuda, Zoysia, Seashore Paspalum
Important Note: Avoid the peak summer heat (late July/August) if possible, as intense sun can dry out seedlings to fast.

Choosing Your Grass Type

Your location dictates which grasses will thrive. Here’s a quick comparison.

Bermuda Grass

Loves full sun and is very drought-tolerant once established.
Best planted by seed in late spring/early summer.
Requires frequent mowing and good drainage.

St. Augustine Grass

The most common Florida lawn grass, known for its wide blades.
Usually established from sod or plugs, not seed.
Prefers coastal areas and tolerates some shade.

Zoysia Grass

Slow-growing but forms a dense, weed-resistant turf.
Can be seeded or plugged in late spring.
Has good shade tolerance compared to other warm-season grasses.

Bahia Grass

Extremely tough and low-maintenance, perfect for sandy soils.
Seeded in late spring or early summer.
Its coarse texture isn’t as lush as other grasses, but it’s very reliable.

Centipede Grass

Called the “lazy man’s grass” for its low fertilizer needs.
Prefers acidic soils and is usually seeded in spring.
It doesn’t tolerate heavy foot traffic or high phosphorus fertilizers.

Step-by-Step Lawn Seeding Guide

Once you’ve picked your time and grass, follow these steps for the best results.

Step 1: Soil Preparation

This is the most critical step. Don’t skip it.

Clear the Area: Remove all weeds, rocks, and old grass. Use a non-selective herbicide if needed, but allow time for it to work before seeding.
Test Your Soil: A soil test from your local county extension office tells you exactly what nutrients and pH adjustments you need. Florida soils often need sulfur to lower pH.
Till and Level: Loosen the top 4-6 inches of soil. Rake it smooth, removing any debris. This gives seeds easy contact with soil.

Step 2: Seeding and Nurturing

Now for the main event.

Apply Seed: Use a broadcast or drop spreader for even coverage. Follow the rate on the seed bag—more is not better. To ensure good contact, lightly rake the seed into the soil or roll the area with a lawn roller.
Apply Starter Fertilizer: Use a low-phosphorus starter fertilizer unless your soil test says otherwise. Florida laws often restrict phosphorus use.
Mulch Lightly: A thin layer of weed-free straw or hay can help retain moisture and protect seeds from birds.

Step 3: Watering and Initial Care

Consistent moisture is non-negotiable for germination.

Water Frequently: For the first 2-3 weeks, keep the top inch of soil constantly moist but not soggy. This usually means light watering 2-3 times a day.
Reduce Schedule: Once grass sprouts and reaches about an inch, water more deeply but less often to encourage root growth.
First Mow: Mow when the grass is about one-third taller than its recommended height. Ensure your mower blade is very sharp.

Common Mistakes to Avoid

Even with good timing, these errors can ruin your efforts.

Planting Too Late: Seeding in fall is risky. Young grass needs 8-10 weeks of solid growth before the first frost to survive.
Overwatering or Underwatering: Both are deadly. Stick to the schedule and adjust for rain.
Using the Wrong Fertilizer: High-nitrogen fertilizers too early can burn seedlings. Stick with starter formula.
Ignoring Weeds: Pre-emergent herbicides cannot be used at seeding time, as they prevent grass seed from germinating. You must hand-pull weeds initially.

FAQ Section

Can I plant grass seed in Florida in the winter?

No, it’s not recommended. Soil temperatures are to low for warm-season grass seeds to germinate. You might see some growth, but it will be weak and susceptible to cold damage.

What is the best month to plant grass seed in Florida?

For most of the state, May and June are ideal. The soil is warm, and afternoon rains are common, which helps with irrigation. In South Florida, March and April are also excellent.

How long does it take for grass seed to grow in Florida?

With proper care, you’ll see sprouts in 7-21 days, depending on the grass type. Bermuda may sprout in a week, while Zoysia can take up to three. Full lawn establishment takes a full growing season.

Can I just throw grass seed on my lawn in Florida?

Simply throwing seed (called “overseeding”) on an existing lawn rarely works well in Florida. Soil contact is poor, and competition is high. For bare spots, rough up the soil first. For a whole new lawn, proper soil preparation is essential.

Is it better to sod or seed in Florida?

Sod gives an instant lawn and is less vulnerable to weeds, but it’s much more expensive. Seeding is cost-effective for large areas and offers more grass variety. Some grasses, like St. Augustine, are typically only available as sod or plugs.

Getting your Florida lawn started right begins with patience and timing. By choosing the correct window for your region and grass type, preparing your soil thoroughly, and providing consistent care, you’ll give your new grass the best possible foundation. Remember, a little extra effort in the planting phase pays off for years with a healthy, resilient turf that can handle the Florida sun and rain.
