I'm trying to tackle 1 acre lawn in suburban Boston that is 50%+ Bent Grass..... I think a total overhaul would be too labor intensive and therefore cost prohibitive. By overhaul I mean spraying everything with RoundUp - using a turf cutter to remove the dead grass/turf - then re-grade and start with fresh seed/fertalizer. Does anyone have an alternative? Do you think I could "beat out" the Bent grass if I aerated and used a split seeder in the Spring and Fall next season? Any thoughts/comments would be very much appreciated.
