Iredell County, NC — Planting Guide
Top priorities for Iredell County, North Carolina gardeners in May
Welcome to May in Zone 7b. These are the moves that will have the biggest impact on your growing season.
-
Time to start basil, cucumber, and kale inside
A seed-starting mix and a sunny window (or a grow light) are all you need. Keep soil warm — around 70°F — for fast germination.
-
Harvest carrots, lettuce, and radish as they ripen
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
June will be here before you know it — start on
- Starting indoors: peppers, eggplant, and hot peppers
- First harvests: basil, carrots, and cucumber

Frost Risk Probability
Based on 31 years of NOAA weather station data from 3 stations
Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.
How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.
| Planting Strategy | Last Spring Frost | First Fall Frost | Frost-Free Days |
|---|---|---|---|
| Conservative (safest) | Apr 21 | Nov 14 | 207 days |
| Cautious | Apr 12 | Nov 6 | 208 days |
| Average year | Apr 7 | Nov 1 | 208 days |
| Optimistic | Mar 25 | Oct 24 | 213 days |
| Aggressive (risky) | Mar 15 | Oct 15 | 214 days |
Not very — frost dates can vary by ±37 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Yes — growing seasons are getting shorter here (about 1.1 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
