Kenilworth, NJ 07091 Frost Dates
When can you plant in Kenilworth, NJ?
Around 04/11 is the usual last spring frost, about 226 days away. The first fall frost typically arrives around 10/31, about 202 frost-free days later.
Zone 7a (0 to 5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Kenilworth, not a forecast for this year.
What to do before the first frost
About 9 weeks of growing season left in Kenilworth before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Plant by 03/30 and you're betting against frost in roughly 9 years out of 10. 04/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
