WINTERIZATION

Depending upon the location of the field and the landscaping nearby , trenching around the perimeter can cut down on grass migration during the off-season .
“ The more water contained in the plant system , the more damage that can happen in the winter ,” said Munie . “ Do a preventive application of fungicide for spring dead spot , if your fields are susceptible to that disease .”
In warm-season areas , field managers can overseed with perennial ryegrass to provide winter color and help

protect bermudagrass from wear over winter . Treat stress areas with additional seed . In cool-season areas , dormant seeding of the normal turfgrass variety should follow dethatching . Topdress after seeding if the budget permits . Consider the use of a growth blanket to encourage germination ( in warm-season areas for winter cover and in cool-season areas for earlier growth in the spring ). Growth blankets are made of lightweight , non-woven geotextiles placed over seeded areas and anchored at the perimeter . They allow sunlight to reach the soil during germination or over winter , raising soil temperatures from 5 ° F to 15 ° F , promoting rapid seed germination or post-winter recovery . Remember that as long as the grass continues to grow , the turf will need irrigation . Turf managers must regularly check under the blankets to ensure no mold or disease develops . ( Alternately , a protective cover of weed-free straw or other material may be applied ).
“ In areas of hard freeze , winterize the irrigation system ,” added Munie .
To make sure irrigation is winter-ready , check each of the system components and make any necessary repairs so that sprinklers , pipe and all other parts will be ready when needed in the spring . Next , drain the system using installed drains or a high-volume , low-pressure compressor or both .
