In central Georgia, winter desiccation is the death of leaves or plants by drying during winter when the plant is either dormant or semi-dormant. Typically, we see the injury on the lawn from desiccation occurring on exposed and elevated sites. Two things happen in these areas of your lawn: moisture tends to runoff, and these areas also receive the most wind.
Centipede can be particularly sensitive to desiccation and winter kill as it does not have as extensive of a root system other warm season grasses as do to hydrate it. It is important to keep in mind that grasses still need moisture during dormancy. If we in don’t receive rainfall for extended periods we have to irrigate here in Macon.
