Dying zoysia-Replace sprinkler heads or mow short to 1" thatch??
Our lawn is dying/dead. Very brown. We have a hunter system with 40+ pop up heads but our ZOYSIA grass is about 2" think and the heads do not clear the grass and therefore are not spraying effectively.
Should I replace all heads with much taller heads (Say 4" pop ups) or mow shorter? The zoysia only has like 1/2" of green at the top so the places where I weedeatered to 1" high left brown dead thatch and no green blades... so I am afraid to cut too short and kill the grass.
