Abilene gardening questions

When is the last frost in Abilene, TX?

Plan around Mar 29. At NOAA's Abilene Regional Airport, TX station, 4.5 mi from the city center, there is a 30% chance of a 32°F frost after that date. Half of springs have their last frost by Mar 20, and after Apr 10 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Mar 6. The 90% and 10% dates are 40 days apart, close to the 36-day median for cities on this site.

When should I plant tomatoes in Abilene, TX?

Start seeds indoors Feb 1 – Feb 15 and set transplants outside Apr 5 – Apr 19, once nights stay above 50°F and the soil is near 60°F. That leaves 221 days between the 30% frost dates, enough for most varieties including 80–85-day slicers. More: tomato planting dates by zone.

How long is the growing season in Abilene?

About 236 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 209 days, and in 1 year in 10 it runs 261 days or more. In fall there is a 10% chance of frost by Oct 28 and a 30% chance by Nov 5. That ranks 50th longest of 55 Texas cities on this site.

When should I plant a fall garden in Abilene?

Count back from the first fall frost (Nov 5): transplant broccoli Aug 13 – Aug 27; sow kale Aug 27 – Sep 24; sow lettuce Aug 27 – Sep 24; sow radishes Sep 24 – Oct 22. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Nov 23. How the math works: succession and fall planting.
