Gunnison County, CO — Planting Guide
June to-do list for Gunnison County, Colorado
June rewards gardeners who work with the weather, not against it. Here's how to stay in step this month in Gunnison County, Colorado.
-
Move basil, cucumber, and kale into the garden
Bring a watering can to the bed. Each transplant gets a drink the moment it's in the ground, not ten minutes later.
-
Seed basil, cucumber, and green beans outdoors
Mark the row. Birds and stray feet both have opinions about unmarked beds.
-
Collect radish, cress, and microgreens at their peak
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.
Looking ahead to July
- Transplants going out: alpine strawberries, aronia, and blackberries
- Starting indoors: basil, cucumber, and kale
- First harvests: carrots, lettuce, and radish
- Fall sowing: carrots, kale, and lettuce

Monthly Watering Calendar for Gunnison 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: In humid climates, watering is usually about timing (morning, not evening, to prevent disease) more than volume. In dry climates, it's about depth (water deep, less often) more than frequency. Gunnison County's 18" annual tells you which side you're on.

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 25 | Sep 30 | 97 days |
| Cautious | Jun 19 | Sep 19 | 92 days |
| Average year | Jun 12 | Sep 10 | 90 days |
| Optimistic | May 29 | Sep 1 | 95 days |
| Aggressive (risky) | May 19 | Aug 8 | 81 days |
Not very — frost dates can vary by ±37 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Slightly — seasons are trending a bit shorter (0.5 days/decade). Stay conservative with planting dates.

What to Plant After Your Harvest
After your first crops finish, use the remaining frost-free days to grow a second round.
Sunlight & Day Length in Gunnison County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
The practical takeaway: Lettuce and cilantro "bolt" (go to seed) when days lengthen. Knowing your day-length curve helps you time spring plantings to harvest before the bolting trigger hits. Gunnison County's daylight ranges shape the planting calendar.

Cover Crops for Gunnison County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Quick context: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Gunnison County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (2 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Jun 17 | Jul 2 | — | Rapid growth, attracts pollinators, suppresses weeds |
| White clover | May 13 | Jul 9 | ✓ Yes | Living mulch, fixes nitrogen, permanent ground cover |
Summer Cover Crops (1 options) — Fill gaps and suppress weeds between plantings
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Sunflowers | Jun 24 | Aug 27 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (5 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Daikon radish | Jul 13 | May 29 | — | Deep taproot breaks compaction, excellent for clay soils |
| Hairy vetch | Jun 20 | May 22 | ✓ Yes | Excellent nitrogen fixer, good for depleted soils |
| Oats | Aug 12 | May 29 | — | Quick biomass, winterkills in cold zones — no spring tillage needed |

| Winter wheat | Jun 18 | May 22 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Gunnison County
Quick context: Wind affects three things gardeners forget: how fast soil dries (more wind = more watering), whether pollinators can work (calm beats gusty), and whether your trellised crops stay upright. Gunnison County sees 10.7 mph on average — a forgiving baseline.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 15 mph Summer: 11 mph
Fall: 13 mph Winter: 15 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
7.5/10
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 1,130 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Gunnison County
How much water you can collect, when to collect it, and what size system you need for your garden.
Why it matters: The first inch of rain washes the roof clean — a first-flush diverter sends it to waste before the barrel fills. Worth the extra $20 for cleaner garden water. Gunnison County gets 18" annually, so you'll fill and flush many times per year.
Annual Collection
8,921 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 1,750 gal tank.
Legal Status
Limited
Your state has quantity limits on rainwater collection — check local regulations before installing large systems.
Best Collection Months
Mar, Apr, May, Jul
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Nov, 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 17.9 inches of rain per year
- A 1,000 sq ft roof can collect roughly 8,921 gallons annually
- Check CO state regulations — rainwater harvesting has quantity limits
- In your dry climate, every drop counts — consider a larger cistern system
- Position collection tanks in shade to reduce evaporation and algae growth
Soil & Growing Conditions in Gunnison County
