Josephine County, OR — Planting Guide
Your May gardening checklist
If you only do a handful of things in the garden this May, make it these. They're sequenced around your zone's frost timing.
-
Transplant basil, cucumber, and peppers 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.
-
Indoor seed-starting week for cucumber, kale, and lettuce
Label every cell. You will absolutely forget which is which otherwise.
-
Basket week: lettuce, radish, and arugula
This is the payoff month. Bring a basket, bring a friend, and get into the beds.
Looking ahead to June
- Starting indoors: basil, peppers, and pole beans
- First harvests: carrots, green beans, and kale

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) | May 12 | Nov 21 | 193 days |
| Cautious | May 3 | Oct 29 | 179 days |
| Average year | Apr 22 | Oct 20 | 181 days |
| Optimistic | Apr 9 | Oct 9 | 183 days |
| Aggressive (risky) | Mar 19 | Sep 30 | 195 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 2.3 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
