When to Fertilize Your Lawn in Tallahassee

Timing is everything with fertilizer. Feed too early and you push tender growth into a late frost. Feed too late in the season and you invite disease heading into winter. Here in North Florida our season runs long, but the windows that matter are clear once you know them.

This is a general schedule for Tallahassee-area lawns. Your grass type and a soil test can shift the details, but the timing below works for most St. Augustine lawns, which is what most of our neighbors are growing.

Wait for the grass to wake up

The most common mistake is fertilizing too early in spring. Warm-season grasses go dormant over winter, and feeding dormant grass just feeds the weeds.

The rule: wait until your lawn has fully greened up and you have already mowed it at least twice. In Tallahassee that usually lands in mid-March to mid-April, not February, no matter how warm a few early days feel.

A simple North Florida schedule

For most local lawns, three feedings a year keeps things healthy without overdoing it:

• Spring (mid-March to mid-April): The first feeding once the grass is actively growing. This sets up strong color and root growth for the season.
• Summer (June, with a lighter touch through the hot months): A summer feeding keeps the lawn dense while it is growing fastest. Use a slow-release nitrogen product so you feed steadily instead of forcing a surge.
• Early fall (September): The last feeding of the year. In North Florida our grasses slow down earlier than in Central or South Florida, so the final application should go down in September, not October or later.

Do not fertilize during dormancy (roughly November through February). The grass cannot use it, and the nutrients either wash away or feed cool-season weeds.

What to put down

If you do not have a soil test telling you otherwise, a complete turf-grade fertilizer with a slow-release nitrogen source is the safe choice. Look for a balanced ratio such as a 16-4-8 or 15-0-15. Slow-release nitrogen is the key phrase: it feeds the lawn gradually, reduces the risk of burning, and is gentler on our waterways.

A few habits that protect your lawn and your wallet:

• Never fertilize a dry, stressed lawn. Water lightly first, or fertilize before expected rain (but not a downpour, which just washes it away).
• Sweep granules off driveways and sidewalks back onto the grass. Fertilizer on pavement runs straight into storm drains.
• Mind local fertilizer guidance. Many Florida communities restrict heavy nitrogen during peak summer rains to protect water quality. When in doubt, lighter and slower is better.

The easy way

Fertilizer timing, rates and product choice are exactly the kind of thing that is simple in theory and easy to get wrong in practice. If you would rather not guess, that is what we are here for.
