Converse County, WY — Planting Guide
Your May planting checklist for Converse County, Wyoming
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.
-
Time to transplant angelica, anise, and borage
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.
-
Direct-sow carrots, kale, and lettuce
Thin ruthlessly once seedlings are up. Crowded roots mean smaller crops from every plant.
A few tasks this May that'll pay off in June
- Transplants going out: basil, cucumber, and kale
- Direct-sowing: basil, cucumber, and green beans
- First harvests: radish, cress, and microgreens

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) | Jun 17 | Oct 3 | 108 days |
| Cautious | Jun 10 | Sep 21 | 103 days |
| Average year | Jun 4 | Sep 18 | 106 days |
| Optimistic | May 21 | Sep 10 | 112 days |
| Aggressive (risky) | May 11 | Aug 31 | 112 days |
Not very — frost dates can vary by ±36 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 1.6 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.
