Indoor seed-starting week for peppers, begonias, and eggplant
Label every cell. You will absolutely forget which is which otherwise.
-
Harvest basil, carrots, and cucumber as they ripen
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
Looking ahead to August
- First harvests: basil, cucumber, and green beans
- Fall sowing: carrots, kale, and lettuce
Eldorado has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around April 24 and the first fall frost arrives around October 21 — a 180-day frost-free season that's long enough for tomatoes, peppers, melons, and a full succession of cool-weather crops on either side. The trick is timing: start warm-season seedlings indoors 6–8 weeks before last frost, harden them off, and plant out the week after your local frost date is statistically safe.
Soils trend Silt Loam — the gold standard for vegetables. Add 2–3" of compost annually to maintain it and you'll outgrow most of your neighbors.
Drought pressure is moderate (9.2 weeks/year on average). Mulching and drip irrigation pay for themselves quickly.

Monthly Watering Calendar for Eldorado
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
The practical takeaway: Most vegetables want about 1 inch of water per week. Eldorado gets 43" a year — months that hit that 1"/week need zero supplemental watering; months that fall short, the table tells you how much to add. Saves you from drowning roots and from drought-stressing plants into bolting.

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) | May 9 | Nov 3 | 178 days |
| Cautious | Apr 28 | Oct 25 | 180 days |
| Average year | Apr 24 | Oct 21 | 180 days |
| Optimistic | Apr 15 | Oct 13 | 181 days |
| Aggressive (risky) | Apr 6 | Oct 3 | 180 days |
Not very — frost dates can vary by ±32 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 2.7 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Eldorado
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. Eldorado's seasonal swing determines which crops can pack growth into spring vs. limp through fall.
Longest Day
14.8 hours
Summer solstice daylight
Shortest Day

Peak Sun Hours
9.8 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 Eldorado
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Why it matters: Soil temperature is a leading indicator. A black plastic mulch can warm soil 5-10°F faster than bare ground — meaningful in Eldorado's spring if you're trying to plant tomatoes earlier.
Plant Warm Crops When
Soil reaches 60°F+
Soil warm enough from May through Oct.
Best Month to Compost

Pest & Disease Pressure in Eldorado
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why it matters: Pest score isn't pass/fail. It's a planning input. Higher scores mean: more compost (resilient plants), wider spacing (air circulation), resistant varieties (built-in defense), and inspection (catch issues at egg stage).
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Moderate — watch for mildew and blight during wet periods.
Seasonal Risk
View 6 common pests in your area
| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | High | Apr, May, Jun, Jul, Aug, Sep |
| Japanese beetles | Moderate | Jun, Jul, Aug |
| Squash vine borers | Moderate | Jun, Jul |
| Tomato hornworms | Moderate | Jun, Jul, Aug |
| Cucumber beetles | Moderate | May, Jun, Jul |
| Stink bugs | Moderate | Jun, Jul, Aug, Sep |
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 Eldorado
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
What this means for you: Why not just leave bare soil? Weed seeds, erosion, nutrient leaching, and crust formation. A cover crop solves all of these for the cost of seeds and one mowing.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |

Wind & Microclimate in Eldorado
Why this matters: 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. Eldorado sees 9.6 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: 12 mph Summer: 9 mph
Fall: 11 mph Winter: 11 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
5.2/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (156 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Eldorado
How much water you can collect, when to collect it, and what size system you need for your garden.
What this means for you: Most gardens use 0.5-1 gallon per square foot per week in summer. Eldorado's 43" annual rainfall is enough to cover most needs if you can capture it. Rain barrels under downspouts are the simplest entry point.
Annual Collection
19,886 gal
Per 1,000 sq ft of roof area (at 80% collection efficiency)
Recommended Setup
6 rain barrels (55 gal each)
For a typical 500 sq ft garden. Serious collectors: consider a 1,500 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Apr, May, Jun, Jul
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jan, 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 39.9 inches of rain per year
- A 1,000 sq ft roof can collect roughly 19,886 gallons annually
