State Gardening Guides

What a state guide contains

All 51 states are covered, and each state page works from the same set of climate facts: the hardiness zone range, the typical last spring freeze and first fall freeze, the resulting frost-free season length, whether the state is predominantly cool-season, warm-season, or transition for turf, and the pests that are listed as regional priorities. From those, the page assembles a planting window, the grass types worth considering, and links to the tools pre-filled for that state.

The zone and frost figures are given as ranges rather than single values, and that is deliberate. A state is a large and climatically varied place — a single number would be wrong for most gardeners inside it. Coastal and mountain states in particular span multiple zones, and the state figure is there to frame the region, not to date your planting. For your own dates, resolve the location with the ZIP lookup, which maps a specific ZIP to a zone and a frost-date pair; if you are in a large metro, the city guide adds the urban-microclimate detail that a state-wide range cannot carry.

Why season length is the number to plan around

Of everything on a state page, the frost-free interval does the most work in practice. It sets which varieties can finish, how many succession sowings fit in a year, and whether a second autumn crop is realistic or a gamble. Two gardens in the same zone can have very different windows — a coastal site with a late first frost and a continental site with an early one may both be zone 6 — so a variety list copied from a neighbour a zone away is a weaker guide than the window you actually have.

The practical consequence is that in a short-season state the answer to a tight window is usually technique rather than a different crop: start indoors, choose earlier-maturing varieties, use row cover or low tunnels, and accept that some long-season crops only work as transplants. In a long-season state the flexibility shifts to succession sowing and autumn cropping, where the same bed produces two or three harvests. Both approaches are on the seasonal checklists, keyed to the zone.

How to use a state guide well

Open your state to get the climate frame, the grass mode, and the regional pest list, then narrow to your own location with the ZIP lookup before you commit to dates. Carry the grass mode into the grass guide to pick a species, use the lawn care scheduler for the mowing and feeding windows, and check the pest guide for the species your state lists as a priority. Finally, treat the freeze dates as typical rather than guaranteed and check a ten-day forecast before transplanting anything tender — that single habit prevents more crop loss than any other adjustment.

All climate figures are drawn from published sources: hardiness zones from the 2023 USDA Plant Hardiness Zone Map, and freeze dates from state cooperative extension normals. They are typical values for planning, not predictions, and every state page says so.
