TURF SITE ESTABLISHMENT
A.TurfGrass SitePreparation.
1. Removetrashanddebris.
2. Control weedswithherbicide. Spraypost-emergencebroadleaf
herbicidesfour tosixweeks beforeseedingor sodding.
3. Gradeavoidingsteepslopes,low areasandpoorlydrainedareas (nomore
than15%formowingsafety).
4. Protectexistingtreesandbedareaswithsiltfencing, edgedbordersor
mulch.
5. Incorporatea2%-3%slopeawayfromthehomeor structure.
6. Soil preparation.
- Till soil to a depth of 2-3”.
- Add 4-5” of top soil.
- Run a soil test.
- Incorporatelimeandfertilizer basedonthesoil sample results.
- Finish grade.
- Roll area with a lawn roller.
- Water.
- Seed or install sod.
B. Methodsof establishinglawns.
1. Seeding.
- Isthe mostcommonandleast expensivewaytostartalawn.
- Seedissownbyhandor witha mechanical devicesuchasarotary or droptypespreader.
- Applyhalftheseedinonedirectionandtheother halfata90degreeangletothefirst pass.
- Roll thesoil lightlytoensuregoodseedtosoil contact.
- Lightlycover theseedwithpeatmossor weedfreestraw.
- Water to stabilize the seed and peat moss or straw.
- Seedingfor cool seasongrasses.
1) September 1- September 15- piedmont region.
2) September 15- October15- coastal region.
3) August15- September1- mountainregion.
4) Emergencyseedingmid-FebruarytoearlyMarch.
- Seedingfor warmseasongrassesMarch1- July1.
- Purchasequalityseed.Readthelabel.
2. Sodding.
- Usingestablishedturf(grass androots) thatiscutinthinlayers andremovedfromgrowingareainstrips.
- Itisthenmovedtothenewlawn,rolledoutandfittedtogether.
- Startthesoddingprocessfromastraight edgetoensureuniformity.
- Buttstripstogether andstagger rowsinabrick pattern.
- Thenewlawnsoil shouldbemoistbeforelayingthesod.
- Water after installing the new sod.
- Install thenewsodwithin24hourstoprevent rootsfrom dryingout.
- Unroll sodifitcannot belaidwithin48hours.
- Soddingprovides aninstantlawn.
- Soddingfor cool seasongrasses-anytimeduringthecooler timesofthegrowingseason.
- Soddingfor warmseasongrassesApril- July 1.
3. Plugging.
- Usessmallplugs or blocksofsodtoplantinholesabout 6-12 inchesapart.
- Verytimeconsumingmethod of planting grass.
- Thisisacommon methodusedformanywarmseason grasses thatarepoor seedproducers.
- Water.
- Pluggingfor warmseasongrassesApril- July 1.
4. Sprigging.
- Uses plantrunners,cuttings or sprigs(cutstems).
- Sprigs arerolledorpressedintothetop½ to1inch ofsoil.
- Water.
- Spriggingis usuallyusedonlarger areassuchasgolfcourses.
- Spriggingfor warmseasongrassesMarch1-July.
C.Carefor newlyestablishedlawns.
1. Irrigating.
- Keepthetop1.5” ofsoil moist bywateringtwotothreetimesadayfor thefirst7to21days.
- Water early in the morning to reduce the risk of disease and water loss.
- Waterestablishedlawns twotothreetimesaweek½ incheach watering.
- Soil shouldbemoistsixtoeightinchestoencouragegood root development.
2. Mowing.
- Mow whengrassis 50% higher thanthedesiredheight.
- Mowtothesuggestheight for thetypeofgrassyouhaveplanted.
- Mow whenthegrassisdrywithasharp,cleanblade.
- Mowingheight:
Grass / Mowingheight
Tallfescue / 2.5- 3.5inches
Kentuckybluegrass / 1.5-2.5inches
Redfescue / 1.5-2.5inches
CreepingBentgrass / .125-.5inch
Centipede / 1-1.5inches
St.Augustine / 2.5-4inches
Bahia / 2-4inches
Bermuda / .75-2inches
Zoysia / .75-2inches
3. Fertilizing.
- Applyfertilizerwitharotaryor droptypespreader.
- Applyhalfthefertilizerinonedirectionandtheother halfata90degreeangletothefirst pass.
- For seededlawnsfertilizesixtoeightweeksafter seed emerges.
- For sodded,pluggedor spriggedlawnsfertilizeeverythreetofour weeksthroughoutthe growingseason.
4. Pestcontrol.
