Viburnum, MO 65566 Frost Dates
When can you plant in Viburnum, MO?
Around 04/11 is the usual last spring frost, about 226 days away. The first fall frost typically arrives around 10/28, about 198 frost-free days later.
The USDA Plant Hardiness Zone Map puts Viburnum in Zone 6b (-5 to 0°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 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Plant by 03/26 and you're betting against frost in roughly 9 years out of 10. 04/30 is the safer bet, historically only a 1-in-10 chance of frost that late.
