Velma, OK: when does the frost end?
Typically, the last spring freeze lands around 03/28, roughly 212 days out. Fall's first freeze usually shows up around 11/07, roughly 227 days after the last spring frost.

Stretching the season past the first frost
With roughly 10 weeks until Velma'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
03/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/18 and only about 1 year in 10 sees frost after that.
