Greenville gardening questions

When is the last frost in Greenville, NC?

Plan around Apr 2. At NOAA's Greenville, NC station, 3.3 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 Mar 27, and after Apr 10 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Mar 13. The 90% and 10% dates are 33 days apart, close to the 36-day median for cities on this site.

When should I plant tomatoes in Greenville, NC?

Start seeds indoors Feb 5 – Feb 19 and set transplants outside Apr 9 – Apr 23, once nights stay above 50°F and the soil is near 60°F. That leaves 215 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 Greenville?

About 227 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 206 days, and in 1 year in 10 it runs 248 days or more. In fall there is a 10% chance of frost by Oct 26 and a 30% chance by Nov 3. That ranks 7th longest of 13 North Carolina cities on this site.

When should I plant a fall garden in Greenville?

Count back from the first fall frost (Nov 3): transplant broccoli Aug 11 – Aug 25; sow kale Aug 25 – Sep 22; sow lettuce Aug 25 – Sep 22; sow radishes Sep 22 – Oct 20. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Nov 22. How the math works: succession and fall planting.

Did Greenville's hardiness zone change on the 2023 map?

No. Going by the zone that covers most of the city's land, Greenville is zone 8a on both the 2012 and the 2023 USDA maps (PRISM/OSU ZIP listings). About 42% of U.S. ZIP codes kept their half-zone in 2023. Why the 2023 map is warmer.

How does Greenville compare with Raleigh, NC?

Both are in zone 8a. The typical last spring frost in Greenville (Apr 2) comes about the same time as in Raleigh, NC (Apr 3), 73 miles away, and the first fall frost is Nov 3 versus Nov 4. Greenville sits about 282 ft lower, which explains part of the gap. The two cities use different NOAA stations.
