Laredo, TX 78043 Frost Dates
Laredo, TX: when does the frost end?
Around 01/20 is the usual last spring frost, about 145 days away. Fall's first freeze usually shows up around 12/25, roughly 344 days after the last spring frost.

Stretching the season past the first frost
With roughly 17 weeks until Laredo'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
01/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/26 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/16 and only about 1 year in 10 sees frost after that.
