When can you plant in Alpine, TX?
Around 04/07 is the usual last spring frost, about 222 days away. The first fall frost typically arrives around 11/01, about 205 frost-free days later.
The USDA Plant Hardiness Zone Map puts Alpine in Zone 8b (15 to 20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here
04/07 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
