Scott Buley, HTT&T, HIGH TECH TURF & TREES Newly seeded and overseeded lawns just 21 days after seeding. High Tech Turf techniques make these new lawns far more successful, AND able to be used far sooner than conventional seeding OR SODDING. For some clients we use naturally selected Roundup Resistant grass seed varieties to create "perfect" lawns. Weed grasses and broadleaf weeds can be far more easily controlled. Even on new putting greens!
