Much of my “lawn” is in fact a field. The portion directly around.my.house is in fact nice grass though, of course there is some clover, etc mixed in. I have never felt the need to water the grass near the house or in the “field”. It’s growth slows in the heat of summer but it hasn’t died as of yet. I’m shocked the moisture in the PNW wouldn’t actually support a lawn without assistance. It doesn’t actually kill the grass if it goes dormant for a bit.
As for my lawnmower, I plan on purchasing another gas lawnmower when the time comes. There is currently no restriction in my state regarding the sale of gas powered lawn equipment.
