Fall in Florida, tempuratures are still warm, but the days are getting shorter, the sunlight has a lower intensity, and as cooler tempuratures move in lawns become slower growing. This is a good time to prepare your lawn for the coming winter months.
The recommended time frame for a fall fertization, September, is about to come to an end. Don't worry if you missed your chance, when spring comes around you can fertilize and your lawn will grow in vigorously.
This is a good time to look for sod webworms. During this time of year they can be very distructive, leaving your lawn with little time to recover before winter dormancy. Watering and excess nitrogen can also cause fungus disease in your lawn. Water your lawn early in the day so moisture can evaporate from the leaves.
