I’ve sanded my Bermuda once a season for the last 3 years. Every year, it has gotten harder and harder to get the scalp down low enough in July/august. Last year, I gave up right before my mower was about to I think And didn’t get the effect I wanted, sand didn’t spread like I wanted because grass was still too high and thick. I would like to sand once my grass first starts greening up, when it is already scalp to the dirt so I don’t have to scalp while it is growing wide open in the summer, it’s just too much work on me and too much strain on my 30 year old 220a mower. Is there any reason not to sand this early, other than delaying the green up by a couple of weeks? I also airate prior to sanding. TIA.
