Landscaping field worker efficiency

So I purchased a residential/commercial landscaping company in 2023 and while our revenue has increased at a modest pace since then, our bottom line has taken a hit. When I took over, the previous owner had some questionable practices to avoid paying overtime at time and a half. Because I intend to someday sell this company, I have made sure all workers are paid legally for the time they work. Having said that, it has been a huge increase in expense that we did not previously have. I would be interested in chatting with any operators/investors with large residential books of business as to how they manage to maximize efficiency amongst their crews, especially during busy seasons. Any insight would be appreciated.
