Greens will always be maintained more intensely than green surrounds. I'm sure all supers on here would agree to that and would have a weak arguement otherwise.
6 acres of greens on a resort course that has play starting early in the morning is either going to take double the man hours or double the man power to have them mowed ahead of play as compared to typical 3 acres. Walk mowing is costly as it is on 3 acres. And I'm sure they're being walk mowed and not triplexed at Bandon.
3 Acres of greens
4 men = 3 hours to mow 18
6 Acres of greens
4 men = 6 hours to mow 18
or.....
8 men = 3 hours to mow 18
Average wage per man = say $11.00 / hr.
3 Acres mowed 365 days year = $48,000
6 Acres mowed 365 days year = $96,000
Then you can just double aerifying costs, topdressing costs, spraying costs, rolling costs etc.
And the golfers don't care if it's 3 or 6 acres. They will be teeing off at the same time no matter what. So in order to mow, roll, topdress or spray....you not only double the manpower to get it done ahead of play, you double the equipment needed to do it....
Roller = $15k
Sprayer = $50 - $75k
Greens mowers = $15k
Granted, fescue may not require the same fertilizer amount as bentgrass....but do we not think fescue is susceptible to major disease in the pacific northwest? The fungicide budget alone would trump any 3 acre bentgrass green fert budget.
Having over 6 acres of greens and needing them to be maintained ahead of play will cost more than double to maintain 3 acres of bentgrass. The only thing "green" about that is the money being spent....
