Local Climate & Conditions
What Lawn Care Looks Like in Jacksonville
Jacksonville’s climate is humid subtropical, with hot, rainy summers and mild, frost-light winters. Lawns grow for nearly 311 days each year, thanks to soil rarely freezing and abundant rainfall from May through September. Extended warmth and humidity boost growth for warm-season grasses—but also encourage weeds, pests, and fungal disease. Sandy, sometimes poorly draining soils mean drainage and water management are essential. Most lawns thrive on a tailored combination of irrigation, sensible mowing, and attentive pest control.

Watering & Soil Management
Watering & Soil Tips for Jacksonville Lawns
Aim for no more than 3/4" water per irrigation. Target early morning, following city ordinances, typically two days per week in summer, one in winter (no watering 10am to 4pm). High water tables and sandy soils mean frequent drainage problems; improve with compost and pine bark. Annual soil testing is wise, adjust pH if advised. Core aerate in active spring growth for best results. Install rain sensors or smart controllers to avoid overwatering, help prevent fungal issues, and keep your watering efficient.

Frequently Asked Questions
Common lawn care questions for Jacksonville, FL
Apply pre-emergent herbicide when soil at 2" reaches 55–65°F for several days—usually Feb–March in spring, and once temps drop below 70°F in Oct–Nov for winter weeds.
St. Augustinegrass (‘Seville’, ‘CitraBlue’) and Zoysiagrass handle partial shade (need 4–6 hours of sun daily). Bahiagrass and centipedegrass are poor choices for shade.
In summer (DST), irrigate up to twice weekly; in winter (EST), once a week. Always water in the early morning and never between 10am–4pm per city ordinance. Use 3/4" per application.
Aerate during active growth—typically March through April—when grasses are out of winter dormancy and recovering quickly. Avoid during winter or periods of heat stress.
Large patch usually appears in cool, damp weather (fall to spring). Gray leaf spot emerges in hot, humid summer. Monitor for yellowing, spots, and water early to deter disease.
