Why St. Augustine Dominates Jacksonville Lawns
St. Augustine grass thrives in Jacksonville's hot, humid summers. It spreads through stolons (above-ground runners), filling in quickly and crowding out weeds. The thick blade gives that carpet-like appearance homeowners want.
Two varieties handle most Jacksonville yards: Floratam for areas with 6+ hours of direct sun, and Palmetto for shadier spots with 4+ hours of sun.
Floratam vs Palmetto: Which One Do You Need?
Floratam St. Augustine
- Needs 6+ hours direct sunlight
- Most common variety in Florida
- Excellent chinch bug resistance
- Fast spreading, fills in quickly
- Coarse texture, dark green color
- Best for open, sunny yards
Palmetto St. Augustine
- Tolerates 4+ hours of sunlight
- Best shade tolerance of St. Augustines
- Finer texture than Floratam
- Better cold tolerance
- Softer blade, emerald green
- Ideal for yards with tree coverage
How to Check Sunlight Hours
Watch your yard throughout the day. Note when direct sun hits each area and when shade takes over. Morning sun counts, but afternoon sun matters more for St. Augustine. If an area gets less than 4 hours of sun, consider shade-loving plants instead—no grass survives without some direct light.
St. Augustine Care Requirements
St. Augustine needs more water than Zoysia or Bermuda. During hot months, expect to water 2-3 times per week if rain doesn't come. Mow at 3.5-4 inches—higher cutting height helps shade the roots and retain moisture.
Fertilize 3-4 times per year during the growing season (March through October). Watch for chinch bugs in summer—they love St. Augustine and can destroy a lawn in weeks if untreated.
Other St. Augustine Varieties
Beyond Floratam and Palmetto, you might encounter Seville, Delmar, and Captiva. These are dwarf varieties with finer texture and better shade tolerance. They're less common but work well in specific situations—usually heavily shaded areas where even Palmetto struggles.
Is St. Augustine Right for Your Yard?
Choose St. Augustine if you want a thick, lush lawn and you're willing to water regularly. It's the default choice in Jacksonville for good reason—it handles our heat, humidity, and sandy soil better than most grasses.
If you want lower maintenance, consider Zoysia instead. It needs less water and mowing once established.
