Converse County, WY — Planting Guide
Converse County, Wyoming gardeners: here's your June plan
A quick June briefing for Converse County, Wyoming gardeners — what's urgent, what's next, and what can wait.
-
Plant out basil, cucumber, and kale
Pinch off the lowest leaves on each seedling before you plant — it reduces water loss while the roots catch up.
-
Seed basil, cucumber, and green beans outdoors
Thin ruthlessly once seedlings are up. Crowded roots mean smaller crops from every plant.
-
Sow sunflower in trays indoors
Your window is short. These crops want several weeks of indoor growth before they go outside.
-
Basket week: radish, cress, and microgreens
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
July will be here before you know it — start on
- Starting indoors: basil, cucumber, and kale
- First harvests: carrots, kale, and lettuce
- Fall sowing: carrots, kale, and lettuce

Monthly Watering Calendar for Converse County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why it matters: Mulch reduces watering needs 30-50% by cutting evaporation. Converse County's 16" annual rainfall might be enough for vegetables in some months and not in others — a 2-3" mulch layer evens the swing.

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.

Sunlight & Day Length in Converse County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why it matters: You can't change the sun. Picking the right day-length-matched varieties for Converse County matters more than any other "fix" you make — and the seed packet tells you (look for "long-day," "short-day," "day-neutral").

Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.

Wind & Microclimate in Converse County
Why it matters: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Converse County averages 11.7 mph. If you garden near coast, ridge, or open plains, you're likely above that — plan for it.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 16 mph Summer: 12 mph
Fall: 11 mph Winter: 16 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
7.1/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
High
Hilly terrain with 1,760 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Converse County
How much water you can collect, when to collect it, and what size system you need for your garden.

Annual Collection
8,123 gal
Per 1,000 sq ft of roof area (at 80% collection efficiency)
Recommended Setup
8 rain barrels (55 gal each)
For a typical 500 sq ft garden. Serious collectors: consider a 2,000 gal tank.

Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Mar, Apr, May, Oct
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Dec
Dry months when you'll rely on stored water — size your storage for this gap.
Rainwater collection tips for your area
- Your county receives approximately 16.3 inches of rain per year
- A 1,000 sq ft roof can collect roughly 8,123 gallons annually
- Rainwater harvesting is fully legal in your state
