Red Hill, PA 18076 Frost Dates
When can you plant in Red Hill, PA?
Around 04/26 is the usual last spring frost, about 241 days away. The first fall frost typically arrives around 10/17, about 175 frost-free days later.
The USDA Plant Hardiness Zone Map puts Red Hill in Zone 7a (0 to 5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 04/26 isn't a guarantee
04/26 is the middle of 30 years of NOAA records, not a promise. Plant by 04/12 and you're betting against frost in roughly 9 years out of 10. 05/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
