Bear Lake County, ID — Planting Guide
Your May gardening checklist
Welcome to May in Zone 5a. These are the moves that will have the biggest impact on your growing season.
-
Move kale, lettuce, and angelica from tray to bed
Harden off for 7 days — a little more sun each day — before planting. That's the difference between a seedling that thrives and one that stalls.
-
Seed basil, carrots, and cucumber outdoors
Succession planting is the secret here. Put in a row now, another in 2 weeks, a third in 4.
-
Collect microgreens at their peak
Morning harvests are best — cooler temperatures mean crisper produce and longer fridge life.
June will be here before you know it — start on
- 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) | Jun 22 | Oct 20 | 120 days |
| Cautious | Jun 15 | Oct 11 | 118 days |
| Average year | May 24 | Sep 24 | 123 days |
| Optimistic | May 6 | Aug 30 | 116 days |
| Aggressive (risky) | Apr 20 | Aug 13 | 115 days |
Not very — frost dates can vary by ±63 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 shorter here (about 3.6 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
