June to-do list for El Paso County, Colorado
June is a pivotal month for El Paso County, Colorado gardens. Focus on these tasks first and you'll set up the rest of the season for success.
-
Move alpine strawberries, aronia, and blackberries into the garden
Your last frost (May 11) has passed. These warm-season crops can handle outdoor soil now.
-
Sow basil, cucumber, and kale in trays indoors
Starting these indoors now means sturdy transplants ready the moment your soil warms up.
-
Pick carrots, lettuce, and radish
If you can't use it all right away, check the food-preservation section of your planner.
Get ahead of July
- Starting indoors: peppers, pole beans, and tomatoes
- First harvests: basil, carrots, and cucumber
- Fall sowing: carrots, kale, and lettuce
Cascade has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around May 11 and the first fall frost arrives around October 6 — a 148-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 Loam — the gold standard for vegetables. Add 2–3" of compost annually to maintain it and you'll outgrow most of your neighbors.
Cascade averages 27.3 drought weeks per year (US Drought Monitor, 2000–present, trend stable). Treat irrigation as a year-round system, not a summer add-on.

Monthly Watering Calendar for Cascade
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why it matters: Watering math is simple: 1 inch of rainfall delivers ~600 gallons to a 1,000 sq ft garden. Cascade's 27" annual rainfall covers some months entirely; others need a few hours of drip irrigation per week. The calendar tells you which is which.

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 27 | Oct 17 | 143 days |
| Cautious | May 19 | Oct 10 | 144 days |
| Average year | May 11 | Oct 6 | 148 days |
| Optimistic | May 4 | Sep 27 | 146 days |
| Aggressive (risky) | Apr 24 | Sep 9 | 138 days |
Not very — frost dates can vary by ±33 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 6 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Cascade
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: 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. Cascade's daylight ranges shape the planting calendar.
Longest Day
14.7 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 Cascade
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
For new gardeners: Air temperature lies. Your air can be 70°F in April but the soil 4 inches down is still 50°F — too cold for tomatoes or peppers to root properly. Cascade's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.
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.

Cover Crops for Cascade
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why this matters: 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 (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 17 | Jul 28 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | May 18 | Aug 11 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Apr 16 | Aug 4 | ✓ 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 | May 24 | Sep 22 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (6 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Austrian winter peas | Aug 1 | Apr 27 | ✓ Yes | Fixes nitrogen, good for heavy clay soils |

Wind & Microclimate in Cascade
For new gardeners: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Cascade averages 9.5 mph — above 10 mph means windbreaks (shrubs, fences, taller crops to windward), staked tomatoes from day one, and an extra round of watering during dry windy spells. Lower wind = lower water bills and fewer broken stems.
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: 14 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
6.5/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (939 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Cascade
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: Most gardens use 0.5-1 gallon per square foot per week in summer. Cascade's 27" annual rainfall is enough to cover most needs if you can capture it. Rain barrels under downspouts are the simplest entry point.
Annual Collection
11,712 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 1,500 gal tank.
