lawn has Tif 419. I am considering doing another top dressing this year (top dressed with sand 3 years ago). I have read several posts on this topic.
Here is my game plan:
Keep it cut to 1/2"
Mid June I will aerate, remove plugs, fertilize, top dress/level with riversand, roll, water, pray for good results.
Any useful links or final words of advise would be appreciated.
