June in Cornish, UT — your action list
Your garden in Cornish, UT is working on a schedule, even when you're not. Here's where you should be this June.
-
Set out basil, cucumber, and kale seedlings
Water the tray well an hour before you transplant. Roots slide out cleanly and settle in faster.
-
Scatter basil, cucumber, and green beans into prepared beds
Rake a smooth bed, make a shallow furrow, drop seeds at the spacing on the packet, water gently, walk away.
-
Collect radish, cress, and microgreens at their peak
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
-
Start your fall crops: carrots, kale, and lettuce
A row cover ready in the garage extends your harvest by weeks once the nights turn cold.
July prep starts now
- Transplants going out: alpine strawberries, aronia, and blackberries
- Starting indoors: basil, cucumber, and kale
- First harvests: carrots, lettuce, and radish
- Fall sowing: alliums, bachelor's button, and crocus
Cornish gardens in a dry climate (only 17" annual precipitation). Watering strategy matters more here than in most of the country — drip irrigation, deep mulching, and morning watering aren't optional, they're table stakes. The flip side: pest and disease pressure are far lower than in humid regions, and your soil temperatures climb fast in spring so you can plant heat-lovers earlier than the zone map suggests.
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.
Cornish averages 34.5 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 Cornish
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
The practical takeaway: In Cornish, the watering question isn't "how often" — it's "is the soil moist 4 inches down?" Stick a finger in. Dry? Water. Damp? Wait. The 17" annual rainfall is just the starting context.

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 24 | Oct 19 | 117 days |
| Cautious | Jun 18 | Oct 2 | 106 days |
| Average year | Jun 11 | Sep 2 | 83 days |
| Optimistic | May 15 | Aug 26 | 103 days |
| Aggressive (risky) | Apr 22 | Aug 9 | 109 days |
Not very — frost dates can vary by ±63 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

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 Cornish
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: The longest day at Cornish's latitude gets longer the further north you go. Strawberries, garlic, onions all care. The shortest day gets shorter — which limits winter growing for greens without artificial light.
Longest Day
15 hours
Summer solstice daylight
Shortest Day
9 hours
Winter solstice daylight
Peak Sun Hours
11.3 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: Your long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

Soil Temperature & Composting in Cornish
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. Cornish'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
Jun
Microbial activity peaks when soil is warm.
Active Composting

Cover Crops for Cornish
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why it matters: You don't need a farm to use cover crops. A 4x8 raised bed accepts cover crops just as well as a half-acre. Cornish's climate determines the calendar; the principle is universal.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Jun 19 | Jul 8 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Cornish
The practical takeaway: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Cornish averages 4.4 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: 12 mph
Fall: 12 mph Winter: 14 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
6.8/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
High
Hilly terrain with 2,924 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Cornish
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: Rainwater scales linearly with roof area. A 2,000 sq ft roof in Cornish captures ~1,200 gallons per 1" of rain — given 17" annual rainfall, that's thousands of gallons a year if you have storage to hold it.
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 UT 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
