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 13 | Oct 13 | 122 days |
| Cautious | Jun 4 | Oct 6 | 124 days |
| Average year | May 27 | Sep 27 | 123 days |
| Optimistic | May 19 | Sep 21 | 125 days |
| Aggressive (risky) | May 8 | Sep 11 | 126 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 2.4 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Montezuma County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Quick context: Plants use day length as their seasonal clock. Some crops flower when days lengthen (most flowers), some when days shorten (chrysanthemums, soybeans). Montezuma County's curve is the timing layer beneath everything you grow.
Longest Day
14.6 hours
Summer solstice daylight
Shortest Day

Winter solstice daylight
Peak Sun Hours
10.1 hr/day peak (summer)
Peak sun hours (green dashed line below) account for cloud cover — this is the usable direct sunlight your garden actually receives. Most vegetables need 6+ peak sun hours.
Onion tip: Your long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

Soil Temperature & Composting in Montezuma County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
The practical takeaway: Soil heats slower than air in spring and cools slower in fall. That's why "warm" April air doesn't mean "plant tomatoes" — soil still trails by weeks. Montezuma County's monthly soil curve makes the lag visible.
Plant Warm Crops When
Soil reaches 60°F+
Soil rarely reaches 60°F — use black plastic mulch to warm soil.
Best Month to Compost
Jul
Microbial activity peaks when soil is warm.
Active Composting
2 months
Short season — insulate pile or use indoor vermicomposting.

Highlighted rows = soil 60°F+ (safe for warm-season transplants). Compost finishes fastest during peak activity months.
Pest & Disease Pressure in Montezuma County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why this matters: Pest pressure is a function of climate, not effort. Montezuma County's baseline tells you how much vigilance is normal. A bad pest year in low-pressure region = a normal year in high-pressure region.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.

Wind & Microclimate in Montezuma County
Why it matters: Plants lose water through tiny leaf pores. Wind accelerates that loss dramatically — a 15 mph day can double a calm day's irrigation need. Montezuma County's 10.2 mph background wind is something to design around, not against. Windbreaks made of perennial shrubs save more water than any drip system.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 15 mph Summer: 10 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
6.7/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (960 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Montezuma County
How much water you can collect, when to collect it, and what size system you need for your garden.
The practical takeaway: Rainwater is unchlorinated, unfluoridated, and at ambient temperature — plants actually prefer it. Montezuma County's 15" annual rainfall means even a small 50-gallon barrel catches enough for a few weeks of garden watering between storms.
Annual Collection
7,725 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.
Legal Status
Limited
Your state has quantity limits on rainwater collection — check local regulations before installing large systems.
Best Collection Months
Apr, May, Aug, 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 15.5 inches of rain per year
- A 1,000 sq ft roof can collect roughly 7,725 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 Montezuma County
Soil Type
Loam
Soil pH 6.4–7.7 · Well Drained drainage
