Florida Lawn Care Calendar
A complete month-by-month guide to keeping your St. Augustine and Zoysia grass healthy, green, and weed-free year-round in Manatee County.
When should I mow my lawn in Florida?
In Florida, you should mow your lawn weekly from March through October during the active growing season. From November through February, bi-weekly or as-needed mowing is typically sufficient as the grass enters semi-dormancy. Maintaining a height of 3.5 to 4 inches for St. Augustine grass is critical for root health year-round.
Spring (March - May)
The growing season kicks off. Focus on weed prevention, establishing deep roots, and proper mowing heights.
March
- Spring green-up begins
- Resume regular weekly mowing
- Check irrigation systems for coverage
April
- Apply spring fertilizer (check local ordinances)
- Watch for early signs of chinch bugs
- Mow St. Augustine at 3.5 to 4 inches
May
- Increase mowing frequency to manage rapid growth
- Treat for broadleaf weeds before summer rains
- Ensure irrigation is running 2x per week
Summer (June - August)
Peak heat and heavy rains. Focus on disease management, pest control, and maintaining a tall canopy.
