Caldwell County, NC — Planting Guide
Your May gardening checklist
Welcome to May in Zone 7b. These are the moves that will have the biggest impact on your growing season.
-
Transplant alpine strawberries, aronia, and blackberries outside
Plant tomatoes deep — bury the stem up to the first true leaves to grow extra roots. Everything else goes in at the same depth it grew in the tray.
-
Sow basil, cucumber, and kale in trays indoors
Your window is short. These crops want several weeks of indoor growth before they go outside.
-
Start harvesting carrots, lettuce, and radish
Morning harvests are best — cooler temperatures mean crisper produce and longer fridge life.
Get ahead of June
- 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 24 | Nov 6 | 196 days |
| Cautious | Apr 16 | Nov 1 | 199 days |
| Average year | Apr 10 | Oct 26 | 199 days |
| Optimistic | Apr 5 | Oct 20 | 198 days |
| Aggressive (risky) | Mar 26 | Oct 13 | 201 days |
Not very — frost dates can vary by ±29 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 longer here (about 3.4 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
