Middleburg, VA 20105 Frost Dates
When can you plant in Middleburg, VA?
Around 04/13 is the usual last spring frost, about 228 days away. The first fall frost typically arrives around 10/26, about 195 frost-free days later.
The USDA Plant Hardiness Zone Map puts Middleburg 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 04/13 isn't a guarantee
04/13 is the middle of 30 years of NOAA records, not a promise. Plant by 03/29 and you're betting against frost in roughly 9 years out of 10. 05/01 is the safer bet, historically only a 1-in-10 chance of frost that late.
