What to Look for Before Buying Best Fertilizer For Floratam Grass
Selecting the appropriate fertilizer for Floratam grass requires understanding both the specific needs of St. Augustinegrass varieties and the characteristics of different fertilizer types. This comprehensive buying guide addresses key factors that directly impact your lawn care success.
Key Consideration: Floratam Compatibility
Before purchasing any fertilizer for Floratam grass, critical examination of product labels is essential. Several popular weed-and-feed products explicitly state DO NOT USE ON St. Augustinegrass (including Floratam)—this warning exists because the herbicides used to kill broadleaf weeds can damage or kill Floratam grass. Always verify product safety before application.
NPK Ratio Understanding
The three numbers on fertilizer packaging represent nitrogen (N), phosphorus (P), and potassium (K). For Floratam maintenance, common ratios include 29-0-0 for quick greening, 38-0-4 for sustained feeding, and 24-25-4 for new sod establishment. Higher nitrogen promotes rapid greening, while balanced phosphorus supports root development in new installations.
Application Method Preference
Consider whether liquid or granular application fits your situation. Liquid fertilizers like Scotts Liquid Green Max provide faster absorption and easier application but require more frequent use. Granular products like Turf Builder Lawn Food offer slower, steadier feeding but require spreader equipment.
Coverage Area Calculation
Accurately measure your lawn before purchasing. Products range from 1,000 sq. ft. (small bag starter food) to 12,000 sq. ft. (large weed-and-feed bag). Purchasing the correct coverage prevents waste and ensures proper application rates.
Frequency and Timing Requirements
Different fertilizers require different application frequencies. Some products feed for up to 10 weeks (O.M. Scott Natural Grass Food), while others may require monthly applications for optimal results. Consider your time availability and commitment level when selecting products.
Budget Considerations
Calculate cost per application rather than purchase price alone. While larger bags sometimes offer better value, they waste money if unused. For small yards, economical per-application costs matter more than bulk pricing.
Frequently Asked Questions
Can I use weed and feed on Floratam grass?
No—several Scotts weed-and-feed products explicitly state DO NOT USE ON St. Augustinegrass (including Floratam). The herbicides that kill dandelions, clover, and other broadleaf weeds can also damage or kill Floratam grass. For weed control on Floratam, consider manual removal, selective post-emergent herbicides labeled safe for St. Augustinegrass, or avoid weed-and-feed products altogether.
What NPK ratio is best for Floratam grass?
For established Floratam lawns, formulas with higher nitrogen content (29-0-0 or 38-0-4) promote vibrant green color. For new sod installation, use starter fertilizers with balanced phosphorus (24-25-4 or 7-12-15) to support root development.
How often should I fertilize Floratam grass?
The frequency depends on the product type. Liquid fertilizers like Scotts Liquid Green Max typically need monthly applications during the growing season. Granular products like Turf Builder Lawn Food usually require 6-8 week intervals. Natural products like O.M. Scott Natural Grass Food feed for up to 10 weeks per application.
When is the best time to fertilize Floratam grass?
Fertilize Floratam grass in spring after the grass begins actively growing (typically when daytime temperatures consistently reach 60°F). Continue applications through summer, stopping in late fall before temperatures drop significantly. Avoid fertilizing during drought stress or extreme heat.
Is Scotts Liquid Green Max safe for Floratam?
Yes—Scotts Liquid Green Max and similar liquid fertilizers without weed-killing herbicides are generally safe for Floratam grass. Always verify by checking the product label for any St. Augustinegrass restrictions before application.
Can I use organic fertilizers on Floratam?
Yes—organic options like O.M. Scott Natural Grass Food or Simple Lawn Solutions Advanced 16-4-8 with seaweed and fish emulsion work well on Floratam. These products provide nutrition without synthetic chemicals that might stress the grass.
How long does it take to see results from fertilizer?
Results vary by product. Liquid fertilizers like Scotts Liquid Green Max show results in approximately 3 days. Granular products typically show visible greening in 3-7 days. Starter fertilizers for new sod show results over 3-4 weeks as roots establish.
What’s the difference between liquid and granular fertilizers?
Liquid fertilizers absorb faster for quick results but require more frequent applications. Granular fertilizers release slowly over time but require spreader equipment. Both can be effective for Floratam—the choice depends on your preference for application method and result speed.
Final Verdict
After comprehensive testing and analysis of all products, our top recommendation for most Floratam owners is Scotts Liquid Green Max Lawn Food for its exceptional combination of fast results, ease of application, and proven safety for St. Augustinegrass varieties.
The runner-up position goes to Scotts Turf Builder Starter Food for New Grass, which delivers outstanding results for new sod installation with its specialized 24-25-4 ratio. For those prioritizing natural ingredients, O.M. Scott and Sons Natural Grass Food provides excellent results without synthetic chemicals.
Remember: Always verify product labels before purchasing, as several popular weed-and-feed products explicitly warn against use on Floratam. With proper product selection and consistent application, your Floratam lawn can achieve the vibrant, healthy appearance that makes this grass variety so popular.
