When can you plant in Iola, TX?
Around 02/27 is the usual last spring frost, about 183 days away. The first fall frost typically arrives around 11/30, about 278 frost-free days later.
Zone 9a (20 to 25°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 Iola, not a forecast for this year.
What to do before the first frost
About 13 weeks of growing season left in Iola before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 02/27 isn't a guarantee
02/27 is the middle of 30 years of NOAA records, not a promise. Plant by 01/31 and you're betting against frost in roughly 9 years out of 10. 03/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
