Houma, LA 70344 Frost Dates
Houma, LA: when does the frost end?
Typically, the last spring freeze lands around 02/08, roughly 164 days out. Fall's first freeze usually shows up around 12/19, roughly 311 days after the last spring frost.

Stretching the season past the first frost
With roughly 16 weeks until Houma's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
02/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/12 and only about 1 year in 10 sees frost after that.
