Things to Do in the October Garden: Turf

Monitor soil moisture for continued turf health, as October can be a dry month for Georgia. Ideally, 1” of water per week keeps turf hydrated. Make lime applications if necessary, according to soil test results, to adjust pH. 

Cool-season turf – Important fall maintenance tasks include: 

  • New turf can be established. 
  • Fall fertilization will begin mid-month. 
  • Liming 
  • Core aeration 
  • Interseeding 
  • Preemergent applications for winter annual weed control (complete by mid-month) – no preemergence if seeding or sodding is planned
  • Continue monitoring for disease in turf, as warm temperatures, rain, and high humidity can persist through the fall. 
  • Insect pests can still present problems for turf. Continue monitoring for armyworms, chinch bugs, and sod webworms. 

Warm-season turf – The growing season is nearly done, but important care steps continue! 

  • No additional applications of nitrogen-containing fertilizer are necessary, as warm-season turf prepares for dormancy.  Potassium (e.g. 0-0-20 or 0-0-60) applications can help abate winter stress and diseases.
  • Preemergent applications for winter annual weed control (complete by mid-month) 
  • Continue monitoring for disease in turf, as warm temperatures, rain, and high humidity can persist through the fall. 
  • Insect pests can still present problems for turf. Continue monitoring for armyworms, chinch bugs, and sod webworms.
