Hot Springs County, WY — Planting Guide
May to-do list for Hot Springs County, Wyoming
Your garden in Hot Springs County, Wyoming is working on a schedule, even when you're not. Here's where you should be this May.
-
Get kale, lettuce, and angelica in the ground
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.
-
Put basil, carrots, and cucumber seeds straight in the ground
Succession planting is the secret here. Put in a row now, another in 2 weeks, a third in 4.
-
Bring in the cress and microgreens
Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
A few tasks this May that'll pay off in June
- Transplants going out: basil, cucumber, and peppers
- Starting indoors: cucumber, kale, and lettuce
- First harvests: lettuce, radish, and arugula

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) | May 22 | Oct 15 | 146 days |
| Cautious | May 13 | Oct 8 | 148 days |
| Average year | May 11 | Oct 2 | 144 days |
| Optimistic | May 6 | Sep 24 | 141 days |
| Aggressive (risky) | Apr 26 | Sep 17 | 144 days |
Not very — frost dates can vary by ±26 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 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
