Springdale gardening questions
When is the last frost in Springdale, AR?
Plan around Apr 11. At NOAA's Fayetteville Exp Stn, AR station, 6.3 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 Apr 4, and after Apr 22 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Mar 24. The 90% and 10% dates are 35 days apart, close to the 36-day median for cities on this site.
When should I plant tomatoes in Springdale, AR?
Start seeds indoors Feb 14 – Feb 28 and set transplants outside Apr 18 – May 2, once nights stay above 50°F and the soil is near 60°F. That leaves 197 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 Springdale?
About 209 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 188 days, and in 1 year in 10 it runs 233 days or more. In fall there is a 10% chance of frost by Oct 17 and a 30% chance by Oct 25. That is the shortest of the 5 Arkansas cities on this site.
When should I plant a fall garden in Springdale?
Count back from the first fall frost (Oct 25): transplant broccoli Aug 2 – Aug 16; sow kale Aug 16 – Sep 13; sow lettuce Aug 16 – Sep 13; sow radishes Sep 13 – Oct 11. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Nov 9. How the math works: succession and fall planting.
Did Springdale's hardiness zone change on the 2023 map?
Yes. Most of Springdale was zone 6b on the 2012 map and is zone 7a on the 2023 map — half a zone warmer, like about 56% of U.S. ZIP codes. The shift comes from a newer 1991–2020 averaging period plus more weather stations and better mapping; it does not mean last frost comes earlier. Why the 2023 map is warmer.
How does Springdale compare with Fort Smith, AR?
Springdale is zone 7a and Fort Smith is zone 8a. The typical last spring frost in Springdale (Apr 11) comes about 8 days later than in Fort Smith, AR (Apr 3), 59 miles away, and the first fall frost is Oct 25 versus Nov 1. Springdale sits about 874 ft higher, which explains part of the gap. The two cities use different NOAA stations.
