These are the grass types that grow in USDA hardiness zone 7. Pick yours for a month-by-month calendar tuned to this zone’s climate. Zone 7 sits in the transition zone, where cool- and warm-season grasses overlap and a “false spring” can wreck pre-emergent timing. Watch soil temperature, not the calendar.
The typical dates our alert engine would have texted each lawn, replayed with today's rules on archived weather from 2019 to 2025. Each range runs from the earliest to the latest of the cities listed above its table. Simulated dates, not texts we sent or observed emergence.
