Jacksonville Lawn Care Calendar — Month-by-Month Guide for 2026

For sod, do not apply fertilizer before planting or as an early establishment shortcut. Follow the reviewed new-sod guidance.

After maintaining lawns throughout Northeast Florida for over a decade, I've learned that timing is everything when it comes to lawn care in Jacksonville. Our unique climate—with mild winters, hot humid summers, and distinct wet and dry seasons—requires a strategic approach that many generic lawn care guides simply don't address.

Whether you have St. Augustine grass in Ponte Vedra, Zoysia in Mandarin, or Bermuda grass near NAS Jax, this detailed calendar will help you maintain a beautiful, healthy lawn year-round while working with, not against, Jacksonville's climate patterns.

Climate Considerations for 2026

Jacksonville sits in USDA Hardiness Zones 9a and 9b, with average winter lows rarely dropping below 25°F. Our growing season typically runs from March through October, with peak growth during the hot, humid summer months.

Key Climate Factors:

• Rainfall patterns: Wet season (June-September), dry season (October-May)
• Temperature extremes: Summer highs in the 90s, winter lows occasionally in the 20s
• Humidity: High year-round, affecting disease pressure and watering needs
• Storm season: Hurricane season runs June 1 - November 30

Grass Types and Their Characteristics

St. Augustine: Most popular in Jacksonville, thrives in heat and humidity, moderate shade tolerance Zoysia: Heat and drought tolerant, slower establishment, excellent durability Bermuda: Extremely heat tolerant, full sun requirement, goes dormant in winter

Weather Expectations

January typically brings our coolest weather, with average highs around 65°F and lows near 45°F. Frost is possible, especially in northern Duval County areas like Fernandina Beach and Callahan.

St. Augustine Grass Care

• Mowing: Maintain dormant grass at 3-4 inches if growth occurs
• Watering: Minimal—only if extended dry period (7+ days without rain)

• Weed Control: Apply pre-emergent herbicide for summer annual weeds

Zoysia Grass Care

• Status: Fully dormant and brown
• Mowing: Only if winter weeds are present
• Watering: None needed unless extreme drought
• Preparation: Plan spring renovation projects

Bermuda Grass Care

• Status: Dormant and brown
