Nevada County, CA — Planting Guide
Your May game plan for Nevada County, California
Each item below is timed to Nevada County, California's frost dates and soil temperatures. Skip nothing, stress about nothing.
-
Move basil, cucumber, and kale into the garden
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.
-
Plant basil, cucumber, and green beans from seed, right in the garden
Mark the row. Birds and stray feet both have opinions about unmarked beds.
-
Pick radish, cress, and microgreens
Morning harvests are best — cooler temperatures mean crisper produce and longer fridge life.
A few tasks this May that'll pay off in June
- Starting indoors: basil, cucumber, and kale
- First harvests: carrots, lettuce, and radish

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) | Jun 5 | Nov 25 | 173 days |
| Cautious | May 21 | Nov 4 | 167 days |
| Average year | May 10 | Oct 22 | 165 days |
| Optimistic | Apr 25 | Oct 6 | 164 days |
| Aggressive (risky) | Apr 11 | Sep 21 | 163 days |
Not very — frost dates can vary by ±54 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 4.7 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
