If you really want to control the problem, till the entire affected area &
apply an appropriate soil fumigant or steam. That's probably the only
realistic100% method of control. Be learly of using sod in the area, as
that is a primary vector of purple & yellow nutsedge in my experience.

It has been a real struggle trying to get rid of nut-grass in our fescue
lawn. Last year we used Round-up and re-seeded thereafter. The
nut-grass has come back with vengeance. This year we have treated the
lawn
with Ortho Nut-grass and Crabgrass killer. No luck. The nut-grass is
growing like mad. We even got down on our knees and tried to dig them out
as deep as possible. This method will take us another month and a lot
of blisters. Is there hope? Any suggestions?
