In reading UGA's website about dethatching I am a little confused. According to the bermuda care calendar they suggest June and July as best time to dethatch, but in another UGA publication it suggests to do this prior to greenup (Jan/Feb). I did find more information leading me to believe that Jan to Feb would be the best time, provided you were prepared for weeds that may come up. I plan on power raking this week and then follow up with a core aeration shortly after, and then an application of pre-m in 10-14 days. If I am incorrect please guide me in the right direction.
