Preparing St. Augustine turf for the
winter in colder areas.
Covering the lawn with leaves may help some to protect the St.
Augustinegrass from freezing temperatures. However, if you apply
heavy a layer of leaves, they could create a problem by reducing
available oxygen to the St. Augustinegrass.
Outlined below are some cultural practices that will prepare
Augustinegrass for winter months. However, remember that if you
extended periods of temperatures in the single digit numbers,
probably loose some of the St. Augustinegrass no matter what.
keep in mind that our winters in the south have been very mild
past ten plus years. Things could change.
1. Water the lawn in the winter months. If you don't have any
or snow over a 4 to 5 week period, then apply some supplemental
irrigation to the lawn. Adequate soil moisture will help protect
grass from freezing temperatures.
2. Don't over fertilize. I would recommend 2 to 3 lbs. of nitrogen
1,000 sq. ft. per year. Fertilize in late spring mid-summer and
again in mid-September. Actually, twice a year (spring and fall)
probably be enough at the rate of 1 pound of nitrogen per 1,000
with each fertilization.
3. Mow the lawn at about 2.5 to 3.0 inches.
4. Be careful with the application of herbicides, especially
spring months. I would recommend not using a preemergent herbicide
the spring months.
