Worthington, PA 16034 Frost Dates
When can you plant in Worthington, PA?
Around 04/16 is the usual last spring frost, about 231 days away. The first fall frost typically arrives around 11/02, about 199 frost-free days later.
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 Worthington, not a forecast for this year.
What to do before the first frost

Why 04/16 isn't a guarantee
04/16 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 05/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
