Consequences of Improper Fertilization
Not fertilizing right can harm your St. Augustine lawn. Too much fertilizer can cause too much thatch, make it more prone to diseases, and harm the environment. It’s important to follow the right lawn care tips to avoid these problems.
| Proper Fertilization | Improper Fertilization |

Seasonal Considerations for Fertilizing St. Augustine Grass
Knowing when to fertilize St. Augustine grass in Florida is key to a healthy lawn. The best time to fertilize changes with the seasons. It matches the grass’s growth and the weather.
Spring Fertilization
Wait for the last frost before feeding your lawn in spring. This is usually 3 weeks after it starts to green up. Then, spread 1 pound of soluble nitrogen per 1,000 square feet every 8 weeks. Or, use 1.5 pounds of slow-release nitrogen every 10 weeks.
Summer Fertilization
Keep up with fertilizing in summer to keep your lawn growing and looking great. From June to September, add 1 to 1.5 pounds of nitrogen per 1,000 square feet every 8 to 10 weeks. Choose fertilizers with little phosphorus to avoid soil buildup.
Fall Fertilization
Fall is a key time for fertilizing St. Augustine grass. October is especially important for getting your lawn ready for winter. Use a “winterizer” fertilizer with a 0-0-10 mix in November to help your lawn survive the cold.
Winter Fertilization
Don’t fertilize your lawn in winter unless you live in a specific area of Florida. November is usually the last month you should fertilize, says the University of Florida. Just water your lawn now and then to keep it from drying out.
| Season | Fertilization Timing | Nitrogen Application |
|---|---|---|
| Spring | 3 weeks after greening | 1 lb soluble N / 1000 sq ft every 8 weeks |
| Summer | June to September | 1-1.5 lbs N / 1000 sq ft every 8-10 weeks |
| Fall | October to November | Use “winterizer” fertilizer (0-0-10) |
| Winter | Not recommended | Focus on watering to prevent drought damage |
Best Time to Fertilize St. Augustine Grass in Florida
Fertilizing St. Augustine grass at the right time is key to a lush, healthy lawn in Florida. The best fertilizer varies by season and location within the state. Aim for 3-4 applications a year, as advised by the University of Florida.
In south Florida, you might fertilize all year because the grass grows longer. For central and north Florida, fertilize from April to October. Don’t fertilize during drought or when the grass is dormant. Water your lawn 2-3 times a week in spring and 2-4 times in summer for growth.
When picking the best fertilizer for St. Augustine grass, look for a balanced mix. Use a St. Augustine-safe weed and feed about two to three weeks before spring. In winter, use a low-nitrogen fertilizer if your area stays warm.
Local laws might limit when you can fertilize, especially near the coast. Always follow your local rules and consider getting a fertilizer certification if needed. By doing so, you’ll keep your St. Augustine lawn in Florida looking great.
