# Lawn by Season > The largest programmatic lawn care database on the web — city-level seasonal guides, timing calendars, and care schedules for every US city plus Australia, New Zealand, UK, Canada, South Africa, Singapore, and Malaysia. All content is derived from USDA hardiness zones, local frost dates, dominant grass types, and regional climate data. Every page is city-specific, not generic national advice. **Base URL:** https://lawnbyseason.com **Coverage:** 8,700+ pages across 10 countries **Last updated:** April 2026 --- ## What This Site Does Lawnbyseason.com answers the question: "What should I do with my lawn RIGHT NOW, in MY city?" rather than providing generic national lawn advice. Every page is built from structured city-level data: - USDA hardiness zone (US) or local climate zone (international) - Last frost date and first frost date (US) — used to derive exact timing windows - Dominant grass type(s) per city - Grass season: warm-season / cool-season / transition zone - Local water restriction status where applicable All timing recommendations (pre-emergent windows, first mow dates, fertilizer timing, aeration windows) are mathematically derived from per-city frost data — not rounded to regional averages. --- ## Primary Content Clusters ### US Lawn Care — City × Season Pages 2,552 pages covering 500+ US cities across all 50 states.
