Dethatching St. Augustine
I have St. Aug. in my front yard (not the whole yard...the "kidney shape" of grass is surrounded by very large beds) and it needs to be dethatched. I'm ready, it's the right time, and I don't mind the work (it's good exercise!!), but I have always wondered...exactly how much of the dead, brown/white pieces should you remove when you do this?
I mean, do I keep raking and raking 'til I see earth? Because, y'know, you can easily do that in the late winter. It's ALL dead/dormant at this time, so it all comes up pretty easily right now. But then you have large bare patches. Or, do I just do a little bit everywhere, whether I can keep raking more up or not?
