Aeration and top dressing

St Aug/centipede I like a spring or fall aeration. March/April and September/October. I want my grass to be actively growing but without the stress of extreme temps.

I plan to do the same this year with mason sand. Shooting for May/June so growth can be at its best.

Need to do it in the warmer months so the grass can repair itself. May/June would be ideal

I messed up areas of my front yard trying to do this myself w/ mason sand in May. The yard has several low spots and areas that took ~1.5” or more of mason sand killed the centipede under it. I kept waiting for it to show signs of filling in with no prevail. Looked like fairway bunkers, wife was pissed. I had to do an emergency sod patch job in October on top of it.

I think St. Aug would have recovered but the centipede just died.

Can’t add much to the excellent advice others have provided other to emphasize to aerate when the grass is actively growing. For me in BTR, that would be usually be AprilMay for centipede.
