When to Plant Vegetables in New Jersey
Last spring frost (median)
Apr 10
First fall frost (median)
Nov 1
Growing season
~205 days
Across New Jersey, the median last frost falls around Apr 10 and the median first fall frost around Nov 1, from NOAA's 1991-2020 climate normals for the weather station nearest each of the state's ZIP codes. Half of years have a later last frost; 1 year in 10 is later than about Apr 25. Every date in the table below is calculated directly from those two dates using standard, extension-verified planting-offset rules, and the ZIP box recalculates it for your own station.
New Jersey Planting Calendar
| Crop | Method | Spring window | Fall window |
|---|---|---|---|
| Tomatoes (Frost-sensitive) | Start Indoors | Start indoors: Feb 13 - Feb 27 Transplant outdoors: Apr 17 - Apr 24 Transplant once nighttime lows are reliably above 50°F, not just after the calendar frost date. | None |
| Peppers (Frost-sensitive) | Start Indoors | Start indoors: Jan 30 - Feb 13 Transplant outdoors: Apr 24 and later Peppers want warmer soil than tomatoes -- when in doubt, wait the extra week. | None |
| Cucumbers (Frost-sensitive) | Direct SowTransplant | Apr 17 - Apr 24 The real trigger is soil temperature (70°F+ at 1 inch deep), not the calendar -- this window is a practical estimate of when that soil temperature typically arrives after the last frost. | None |
| Beans (Frost-sensitive) | Direct Sow | Apr 10 - Apr 17 Bean seed rots in cold, wet soil -- wait until the soil has warmed to at least 60°F. | None |
| Lettuce (Frost-tolerant) | Direct Sow | Mar 13 - Mar 27 Cold-tolerant -- a good candidate for succession sowing every 2-3 weeks through spring. | Sow by Aug 29 - Sep 8 |
| Carrots (Frost-tolerant) | Direct Sow | Mar 6 - Mar 27 | None |
| Squash / zucchini (Frost-sensitive) | Direct SowTransplant | Apr 10 - Apr 17 Squash doesn’t tolerate cold -- wait for soil to reach about 70°F. | None |
| Broccoli (Frost-tolerant) | Start Indoors | Feb 13 - Feb 27 | Sow by Jul 30 - Aug 9 |
| Spinach (Frost-tolerant) | Direct Sow | Feb 27 - Mar 13 Sow as soon as the soil can be worked -- extension sources cite anywhere from 2-8 weeks before last frost depending on region; this is a middle estimate. | Sow by Aug 19 - Aug 29 |
| Peas (Frost-tolerant) | Direct Sow | Feb 27 - Mar 13 Cold-tolerant -- sow as soon as the soil can be worked. | None |
| Onions (sets or transplants) (Frost-tolerant) | Transplant | Mar 13 - Mar 27 This window is for long-day onion varieties, the standard choice across most of the US. Gardeners in the Deep South growing short-day varieties follow a different fall/winter planting schedule. | None |
| Radishes (Frost-tolerant) | Direct Sow | Feb 27 - Mar 13 Fast-maturing -- a reliable succession crop every 1-2 weeks through spring. | None |
| Corn (Frost-sensitive) | Direct Sow | Apr 10 - Apr 17 Needs soil temperature of at least 50°F to germinate, with 65-75°F optimal for even germination. | None |
| Pumpkins (Frost-sensitive) | Direct Sow | Apr 10 - Apr 17 Soil should reach about 65-70°F. If timing for a fall harvest target, count backward from your target date using the variety’s days-to-maturity instead of using this spring window. | None |
| Beets (Frost-tolerant) | Direct Sow | Mar 13 - Mar 27 | None |
| Cabbage (Frost-tolerant) | Start Indoors | Feb 13 - Feb 27 | None |
| Cauliflower (Frost-tolerant) | Start Indoors | Feb 13 - Feb 27 Extension sources vary more on this crop than most (some cite as few as 4 weeks, others up to 10) -- this range is a defensible middle estimate, usually grown on the same schedule as cabbage. | None |
| Kale (Frost-tolerant) | Direct Sow | Feb 27 - Mar 13 | Sow by Aug 29 - Sep 8 |
| Basil (Frost-sensitive) | Start Indoors | Start indoors: Feb 13 - Feb 27 Transplant outdoors: Apr 24 and later Frost-sensitive, unlike the cold-tolerant crops above -- transplant only after ALL frost risk has passed and soil has warmed to 60°F or more. | None |

The Spacing & Planting Cheat Sheet
When to start, when to plant, how far apart.
Understanding Your Planting Windows
These windows come from a simple, real calculation: take New Jersey's median last-frost and first-frost dates, then apply fixed, extension-verified offset rules for each crop (for example, "start tomato seeds indoors 6-8 weeks before your last frost"). Because the offset rules are the same nationwide but New Jersey's actual frost dates are specific to New Jersey, the resulting dates are genuinely New Jersey's own, not a generic template.
These are statewide medians, though, and your own yard may run warmer or colder depending on elevation, urban heat, or microclimate. Enter your ZIP code in the box at the top of the page for your nearest station's dates. For New Jersey's full zone range from coldest to warmest areas, see the New Jersey Growing Zone page.

Sources & further reading
Frost dates come from NOAA NCEI's U.S. Climate Normals, 1991-2020: for each of New Jersey's ZIP codes, the median last and first 32°F dates at the nearest weather station (an airport station within 15 miles where there is one), with ZIP code points from the U.S. Census Bureau's 2023 ZCTA Gazetteer. The same station data drives our Frost Date Calculator. Planting-offset rules are drawn from US Cooperative Extension sources including UGA, UMN, NC State, Utah State, Iowa State, Penn State, and UConn Extension, cited crop-by-crop in the table above.
