How is sedge spread
How can sedge suddenly show up in a 8'X10' area of a mature and healthy lawn? The lawn has been irrigated and has no drought history since 2006. It is surrounded by similar lawns in all directions. The lawns are mowed by a community landscaper at the same time and schedule.Sedge is showing up in patches throughout the 1100+ single family home development. Can it be spread by windblown seeds from natural areas of the development?
