No zone lookup needed

Start with your ZIP, not a zone map.

Zone-map tools make you find your USDA zone first, then hand you a wide window that can cover many miles. GrowZone starts from your ZIP, shows the frost station and USDA zone behind the answer, then gives one computed date for each crop step.

Just the timing

No seed store hiding behind the calendar.

GrowZone does not sell seeds or plants, so the dates you get are the dates the data gives, not a nudge to buy anything. When it matters, verify with your local extension office before planting high-value crops.

Built for return visits

Never miss your planting window.

No app needed: save any ZIP-and-crop calendar to this browser, then add an email reminder so GrowZone tells you when your start-indoors or transplant week is coming up. One save keeps every date for that crop in one place.

Zone pages still matter

Use zone pages for broad planning, then ZIP pages for the date.

Zone pages help answer regional searches. Every zone page points back to the ZIP lookup because frost stations, not zone labels alone, move vegetable timing.

How frost dates workFrost dates are probability estimates, not guarantees. Here is how to use them without over-trusting them.USDA hardiness zones explainedHardiness zones describe winter survival risk. They help with perennials, but annual vegetable timing still needs frost windows.Starting seeds indoors by zoneSeed-start dates move with your local last frost and the crop's transplant age.Transplanting without shockA local frost date is only part of the decision. Seedlings also need hardening off, warm soil, and a calm weather window.Direct sowing cool-season cropsCarrots, radishes, spinach, lettuce, and peas can often go in before the last frost.Fall planting calendarFall planting counts backward from the first frost instead of forward from the last frost.
