How that changes the visit
Through the wet season we watch the ground as much as the schedule. When a lawn is standing wet we move the visit rather than cut it, and we will tell you when that happens. If your yard holds water in one particular spot every year, point it out to us and we will keep the machine off that spot and finish it by hand.
The rest of it is ordinary good practice that matters more on wet ground: we cut at the top of the height range for the grass, keep the blades sharp so the leaf is cut rather than torn, and change the direction of the passes so wheel tracks do not set into one line.
Clippings go back onto the lawn or come away with us. They do not get left in the street or blown toward a storm drain, because on these streets the storm drains run to the bay. That is part of what Landscape Best Management Practices covers, and we are trained in it.
