Monticello, NY 12732 Frost Dates
When can you plant in Monticello, NY?

Zone 6a (-10 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 Monticello, not a forecast for this year.
What to do before the first frost
About 6 weeks of growing season left in Monticello before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/07 isn't a guarantee
05/07 is the middle of 30 years of NOAA records, not a promise. Plant by 04/25 and you're betting against frost in roughly 9 years out of 10. 05/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
