Westbury 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

Why 04/02 isn't a guarantee
04/02 is the middle of 30 years of NOAA records, not a promise. Plant by 03/18 and you're betting against frost in roughly 9 years out of 10. 04/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
