Richmond, IN 47374 Frost Dates
When can you plant in Richmond, IN?
Around 04/25 is the usual last spring frost, about 240 days away. The first fall frost typically arrives around 10/20, about 176 frost-free days later.
The USDA Plant Hardiness Zone Map puts Richmond in Zone 6a (-10 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
About 8 weeks of growing season left in Richmond before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/25 isn't a guarantee
04/25 is the middle of 30 years of NOAA records, not a promise. Plant by 04/11 and you're betting against frost in roughly 9 years out of 10. 05/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
