When can you plant in Glen Ridge, NJ?

Zone 7b

The last spring frost here typically falls around 04/18, about 233 days from today. The first fall frost typically arrives around 10/24, about 187 frost-free days later.

Glen Ridge sits in USDA Zone 7b (5 to 10°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 8 weeks of growing season left in Glen Ridge before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/18 isn't a guarantee

04/18 is the middle of 30 years of NOAA records, not a promise. Plant by 04/03 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
