Month-by-Month Treatment Calendar
Light winter feeding where county ordinances allow; check local nutrient restrictions
Apply early — soil in Central Florida and the Rio Grande Valley often crosses 55–60°F before most of the country

Continue feeding through peak spring growth
Treat emerged weeds
Feeding continues; many Florida counties begin summer nutrient-ordinance blackout periods around this time

Continue fungal disease monitoring through late summer humidity
Curative treatment if damage appears
Resume feeding as summer nutrient-ordinance blackout periods typically end
Continue feeding through the extended fall growing season
Light feeding continues; growth slows but rarely stops in this zone
Year-round growth means light winter feeding is often appropriate, where local ordinances allow

Feed your lawn at the right time — not on the bag's schedule.

Stop crabgrass before it starts — timing is everything.
Post-Emergent
Kill the weeds that are already there — selectively and safely.
Watering
Water deep and infrequent — not shallow and daily.
Mowing
The one-third rule changes everything about how your lawn looks.
