June in Valley County, Idaho — your action list
We've pulled the most time-sensitive tasks for Valley County, Idaho this June and put them front and centre. Tackle them in order.
-
Move kale, lettuce, and ageratum from tray to bed
Your last frost (June 18) has passed. These warm-season crops can handle outdoor soil now.
-
Put basil, carrots, and cucumber seeds straight in the ground
Thin ruthlessly once seedlings are up. Crowded roots mean smaller crops from every plant.
-
Basket week: microgreens
Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
-
Start your fall crops: carrots, kale, and lettuce
Keep young seedlings shaded and moist in summer heat. A row of taller crops works as natural shade.
Looking ahead to July
- Transplants going out: basil, cucumber, and peppers
- Direct-sowing: celosia, columbine, and echinacea (purple coneflower)
- Starting indoors: cucumber, kale, and lettuce
- First harvests: lettuce, radish, and anemones
- Fall sowing: alliums, crocus, and daffodils
Cascade gardens in a wet, humid climate (51" annually). Cool-season crops like peas, lettuce, kale, and brassicas thrive in spring and fall. The biggest challenges are fungal disease and humidity-loving pests in summer — leaf spot, blight, squash bugs, vine borers. Drip irrigation (not overhead), wide plant spacing for air circulation, and disease-resistant varieties make the difference.
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 30.4 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 this matters: Plants need different amounts of water at different growth stages — heavy at flowering and fruit-set, lighter at establishment. Cascade's 51" annual rainfall is your starting math; the timing tells you when natural rain will cover you and when you need to step in.

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 26 | Oct 8 | 104 days |
| Cautious | Jun 22 | Sep 15 | 85 days |
| Average year | Jun 18 | Sep 3 | 77 days |
| Optimistic | Jun 11 | Aug 28 | 78 days |
| Aggressive (risky) | May 14 | Aug 16 | 94 days |
Not very — frost dates can vary by ±42 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 3.9 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

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 Cascade
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: Photoperiod-sensitive crops will fail spectacularly if planted at the wrong latitude. Sweet onions in Michigan? Tiny. Spanish onions in Florida? Tiny. Match variety to Cascade's daylight pattern and you'll see the difference.

Peak Sun Hours
11 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.
Why it matters: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. Cascade's monthly curve tells you when each crop actually has the conditions to take off.
Plant Warm Crops When
Soil reaches 60°F+
Soil rarely reaches 60°F — use black plastic mulch to warm soil.
Best Month to Compost
Apr
Microbial activity peaks when soil is warm.
Active Composting
0 months
Short season — insulate pile or use indoor vermicomposting.

| Winter wheat | May 30 | May 28 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Cascade
The practical takeaway: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Cascade averages 4.0 mph. If you garden near coast, ridge, or open plains, you're likely above that — plan for it.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 14 mph Summer: 12 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
7.1/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
High
Hilly terrain with 1,546 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
Rainwater Harvesting in Cascade
How much water you can collect, when to collect it, and what size system you need for your garden.
What this means for you: A gravity-fed rain barrel ($75) is the easy entry. A larger cistern ($500-1500) covers a whole growing season. Cascade's 51" annual rainfall determines whether the larger system is overkill or essential.
Annual Collection
8,921 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 1,000 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Mar, Apr, May, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
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 17.9 inches of rain per year
- A 1,000 sq ft roof can collect roughly 8,921 gallons annually
- Rainwater harvesting is fully legal in your state
- In your dry climate, every drop counts — consider a larger cistern system
- Position collection tanks in shade to reduce evaporation and algae growth
