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) | Apr 22 | Nov 17 | 209 days |
| Cautious | Apr 14 | Nov 5 | 205 days |
| Average year | Apr 8 | Oct 28 | 203 days |
| Optimistic | Apr 3 | Oct 23 | 203 days |
| Aggressive (risky) | Mar 18 | Oct 15 | 211 days |
Not very — frost dates can vary by ±34 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 1.6 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Garfield County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Quick context: A 14-hour day in June produces dramatically more photosynthesis than a 10-hour day in November. Garfield County's seasonal swing determines which crops can pack growth into spring vs. limp through fall.

Peak Sun Hours
10.3 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: Day-neutral onion varieties like Candy, Cabernet, and Sierra Blanca perform best in your day-length range.

Organic pest management tips
- Use row covers on susceptible crops during peak pest months
- Apply neem oil preventatively every 7-14 days during active pest season
- Interplant with strong-scented herbs (basil, marigold) to confuse pests
- Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
- Practice crop rotation — never plant the same family in the same spot within 3 years
Cover Crops for Garfield County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
For new gardeners: Cover crops protect microbial life through winter and summer. Bare soil bakes; covered soil stays cooler, moister, and biologically active. The difference shows up in next year's crops.
Spring Cover Crops (4 options) — Build soil before the main growing season

Wind & Microclimate in Garfield County
Quick context: Plants lose water through tiny leaf pores. Wind accelerates that loss dramatically — a 15 mph day can double a calm day's irrigation need. Garfield County's 12.8 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: 13 mph
Fall: 14 mph Winter: 16 mph
Prevailing wind: S. Windy area — plant a windbreak hedge on the S side of your garden.
Windbreak Benefit
9.4/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
Low
Relatively flat terrain (173 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Garfield County
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: A 1,000 sq ft roof captures about 600 gallons from a single 1" rainfall. Garfield County gets 26" of rain a year — a couple of well-placed rain barrels can cover most summer watering. In dry climates the math's even better: every captured gallon is one you don't buy.
Annual Collection
13,008 gal
Per 1,000 sq ft of roof area (at 80% collection efficiency)
Recommended Setup
7 rain barrels (55 gal each)
For a typical 500 sq ft garden. Serious collectors: consider a 2,000 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
May, Jun, Jul, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jan, 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 26.1 inches of rain per year
- A 1,000 sq ft roof can collect roughly 13,008 gallons annually
- Rainwater harvesting is fully legal in your state
