Zone 5 Planting Calendar: What to Plant Each Month

Last updated July 31, 2026

Zone 5 at a glance

Zone 5 runs winter lows of -20 to -10°F, and is conventionally taken to average its last spring frost around April 30 and its first fall frost around October 10 — about 163 frost-free days. Comfortable for nearly every beginner crop, with room for a spring planting and a fall planting of greens.

Sow frost-tolerant crops (peas, spinach, radishes, lettuce, kale, carrots) 6 to 2 weeks before April 30. Plant warm-season crops (beans, zucchini, cucumbers, tomatoes, peppers) 1 to 3 weeks after it. Sow a second round of greens and roots about 10 to 12 weeks before October 10.

Typical regions in zone 5: Iowa, Nebraska, Illinois, Ohio, upstate New York, Massachusetts, Colorado Front Range.

Month by month in zone 5

7 of the 12 months have something to plant in zone 5. Rows marked re-sow are succession sowings — the same crop planted again every 14 days for a continuous harvest, up to the last date it can still mature before October 10.

Nothing to sow outdoors in January, September, October, November, December in zone 5. Crops already in the ground keep growing and keep being harvested. Use the time to plan beds, order seed, build a compost pile, or start long-season crops under a light indoors.

Every crop, sowing to harvest

One row per crop, with the indoor start where it applies, the outdoor planting window, the second fall sowing where the season allows it, and the earliest realistic harvest.

Harvest dates assume the earliest outdoor planting in the window and the crop's published days-to-harvest range. Weather moves all of it.

Growing in zone 5

Comfortable for nearly every beginner crop, with room for a spring planting and a fall planting of greens.

Soil beats calendar. Extension guidance for the hardiest crops is “as soon as the soil can be worked” or “as soon as the soil thaws” — not a fixed date. If you cannot crumble a handful of soil in your fist, wait, whatever the table says. Warm-season crops have a matching rule: beans want 60°F soil, cucumbers and squash 70°F.

This matters most in zone 5. The earliest spring windows above assume the ground has thawed and is workable, and in a late spring it may still be frozen or waterlogged on those dates. A raised bed, which warms 2 to 3 weeks earlier than open ground, is the reliable way to hit the early dates here.

About the bolting warnings. Cool-season crops run to seed and turn bitter in summer heat. The “may bolt in heat” flag above is a rough calendar rule — mid-June to the start of September, the same window across the whole country — because a hardiness zone carries no summer-temperature information at all. In zone 5 treat it as about right, with heat-tolerant varieties and afternoon shade extending it either side.

Where these dates come from. A USDA hardiness zone describes average annual extreme minimum WINTER temperature — it is a winter-survival rating for perennials, not a frost-date band. The frost dates below are widely-used approximations for each zone, not official USDA figures, and a single zone spans hundreds of miles. Treat them as a default guess and replace them with your own local averages wherever you have them.

You can enter your own frost dates in the interactive calendar and every window on it recalculates from your numbers. Look up your local averages on the NOAA last-spring-freeze map. Note that an “average” frost date is the point where the chance of freezing drops below 50 percent, so for tender crops it is worth waiting a week or two past it.

Other zones: zone 3 , zone 4 , zone 6 , zone 7 , zone 8 , zone 9 , zone 10 . Or use the interactive calendar to check a single month.

Zone 5 questions

When is the last frost in zone 5?

Zone 5 is conventionally taken to average its last spring frost around April 30 and its first fall frost around October 10, giving roughly 163 frost-free days. Be aware that a hardiness zone is defined by winter minimum temperature, not by frost dates — these are widely-used approximations, not official USDA figures. Get your real dates from the NOAA freeze-date map or your county cooperative extension office.

What can I plant now in zone 5?

Use the month-by-month table on this page. The pattern is: frost-tolerant crops like peas, spinach and radishes go in 6 to 2 weeks before April 30; warm-season crops like beans, zucchini and tomatoes go in 1 to 3 weeks after it; and cool-season crops get a second sowing about 10 to 12 weeks before October 10.

Can I grow tomatoes in zone 5?

Yes. In zone 5, start tomato seed indoors 6 to 8 weeks before April 30 or buy a seedling, then transplant 1 to 2 weeks after the last frost once nights stay above 50°F. With 163 frost-free days there is comfortable room for any variety, including large beefsteak types.

How many harvests can I get in zone 5?

Two full rounds: a spring planting of cool-season crops, a summer planting of warm-season crops, and a fall sowing of greens and roots in the same beds.

Does a raised bed change these dates in zone 5?

Yes, in spring. A raised bed warms 2 to 3 weeks earlier than open ground, so you can bring the early sowings forward by up to two weeks. Autumn dates are unchanged, since the first frost arrives on the same day regardless of your setup.
