Data-derived guides

Guides

Every guide below is computed from data this directory actually holds: land-grant Extension planting rules, real ZIP-level frost and climate data, and state licensing registries. None of it is generic prose with a keyword in the headline.

City plant guides

Compare plants for your city, with photographs and advice on sun, water and space.

This month's guide

What to plant in September →

Zone-banded planting windows for September, computed from real ZIP-level frost dates, not a single national list.

Per-crop planting guides

When to sow, transplant, and harvest each crop, computed from land-grant Extension planting-window rules localized to real ZIP-level frost dates.

Per-zone growing zone guides

What grows, and when, in each USDA hardiness zone, rolled up from the real ZIPs in that zone's own frost and temperature data. Lives at /zones/{zone}.

"What to plant this month" guides

One page per calendar month, split by zone band so the answer isn't falsely national.

State licence-verification guides

Per-state nursery/dealer licensing registry lookups, with the registry source URL and as-of date on every claim. Built only for the 30 states this directory holds a bulk registry for.
