A Year-Long Sports Field Maintenance Plan

 

March

 Soil testing - send samples off to Cornell or other soils labs as soon as ground thaws or in late fall (every three years)

Scout for areas of  thinned turf and plan for annual weed management and overseeding or re-seeding of bare areas

 Scout for snow mold damage

 April

 Early annual weed management with pre-emergent herbicide (crabgrass) on areas of thin turf

Optimal time for overseeding and fixing bare patches

Optimal time for core cultivation

 Scout for red-thread disease

 Raise mowing height whenever possible

* 1 1/2 inches minimum, 2 1/2 inches optimum, 3 1/2 inches maximum for Kentucky bluegrass and perennial ryegrass

* 2 inches minimum, 3 inches optimum, 5 inches maximum for Tall fescue

 Remember to lower mowing height gradually

 May

 Fertilizer (1 - 2 lbs. N/1,000 sq. ft.)

 Scout for possible need for post-emergent crabgrass management

 Scout for need for broadleaf weed management and make application if necessary

 Scout for red thread disease, leaf spot diseases, anthracnose

 Irrigation

Deep (6 to 8 inches) and infrequent best

Total of 1 to 1 1/4 inches maximum needed each week

Early morning is the best time

Dormant fields in drought should be watered once every four weeks to prevent turf loss

 June

 Fertilizer application late in the month if lower rate of slow-release fertilizer used in   May

 Begin watching for warmer-season diseases (brown patch, pythium blight, summer   patch, etc.)

 Apply grub insecticide to areas with a history of grub problems if using imidacloprid (possibly the best option for fields used for fall sports)

 Optimal time to core cultivate (especially after spring sports are over, and if rainfall is adequate or irrigation possible)

 July

 Continue scouting for warmer-season diseases

 Scout for chinch bugs

 Possible time to core cultivate before fall sports begin

(although use caution on stressed fields)

 August

 Best time for major seeding and renovation work

Optimal time for overseeding

Possible time for core cultivation (through September)

 Scout for grubs and spot treat or take other action if needed

 Continue scouting for warmer-season diseases

 Scout for broadleaf weeds and treat if necessary (through mid-October)

 Fertilizer now or early September (preferred time for fields fertilized once a year)

 September

 Good time for major seeding and renovation work through the middle of September; possible to germinate perennial ryegrass until end of September

 November

 Fertilizer as turf goes dormant (about the time of the last mowing)

  Possible time for core cultivation after fall sports are over

 December through March

 Possible times for dormant seeding of bare patches and thinned areas
