What this guide covers
The Northeast spans USDA hardiness zones 4a through 8a across 11 states, with frost-free growing seasons ranging from 140 days in northern Vermont and Maine to 235 days in Maryland’s coastal plain. Average last spring frost dates shift by nearly seven weeks — from May 8 in zone 4a to Mar 20 in zone 8a — creating a wide performance gap for warm-season crops. In zones 4a–5a, tomato and pepper varieties must mature within a compressed window; in zones 7a–8a, dual spring-and-fall plantings are routine.
The book contains 22,900 words across these sections:
Month-by-month planting calendars
Three sub-regional schedules (Northern New England, Southern New England, Mid-Atlantic) covering the full range from zone 4a mountain gardens to zone 8a Chesapeake Bay lowlands. Each calendar distinguishes between direct-sow, transplant, and indoor seed-starting windows.
50+ crop profiles
Variety recommendations selected for cold tolerance, short-season maturity, and performance in acidic and rocky soils typical of the region. Each profile includes days-to-maturity data critical for zones 4a–5a where the frost window is tight.
Regional growing strategies
- Season extension quantified by technique: row covers gain 2–4 weeks; cold frames gain 4–6 weeks; high tunnels enable March-through-November production in zones 5a–6b
- Rocky and acidic soil management — pH correction rates, raised-bed construction for shallow-bedrock sites, and no-dig approaches for established gardens
- Fall and winter cropping for zones 6a–8a: cold-hardy greens, root vegetables, and overwintering alliums with expected yield timelines
- Wildlife management (deer, woodchucks, voles) with fence specifications and deterrent efficacy data
- Compact-space and container strategies for urban gardens in Boston, New York, Philadelphia, and Baltimore
Who this guide is for
Gardeners in New York, Pennsylvania, New Jersey, Connecticut, Massachusetts, Maine, New Hampshire, Vermont, Rhode Island, Delaware, or Maryland (USDA zones 4a–8a) who need planting dates and variety choices calibrated to Northeastern soils, frost patterns, and microclimates.
The guide is updated for the 2026 USDA Hardiness Zone Map and includes variety recommendations tested across New England and Mid-Atlantic conditions. Available in paperback and Kindle on Amazon.
