Spokane County, WA — Planting Guide
Your June gardening checklist
If you only do a handful of things in the garden this June, make it these. They're sequenced around your zone's frost timing.
-
Get alpine strawberries, aronia, and blackberries in the ground
Pinch off the lowest leaves on each seedling before you plant — it reduces water loss while the roots catch up.
-
Start basil, cucumber, and kale indoors
A seed-starting mix and a sunny window (or a grow light) are all you need. Keep soil warm — around 70°F — for fast germination.
-
Pick carrots, lettuce, and radish
If you can't use it all right away, check the food-preservation section of your planner.
A few tasks this June that'll pay off in July
- Starting indoors: peppers, pole beans, and tomatoes
- First harvests: basil, carrots, and cucumber
- Fall sowing: carrots, kale, and lettuce

Monthly Watering Calendar for Spokane County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Quick context: Mulch reduces watering needs 30-50% by cutting evaporation. Spokane County's 20" annual rainfall might be enough for vegetables in some months and not in others — a 2-3" mulch layer evens the swing.

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 12 | Oct 21 | 131 days |
| Cautious | May 21 | Oct 6 | 138 days |
| Average year | May 11 | Sep 27 | 139 days |
| Optimistic | Apr 30 | Sep 18 | 141 days |
| Aggressive (risky) | Apr 19 | Sep 2 | 136 days |
Not very — frost dates can vary by ±54 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

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

Peak Sun Hours
11.2 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 Spokane County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
For new gardeners: Cold soil = stunted starts. A bean seed planted in 55°F soil rots before it germinates. Same seed in 65°F soil sprouts in 5 days. Spokane County's soil temperature pattern shows you the difference month to month.

Cover Crops for Spokane County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
For new gardeners: 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.

Wind & Microclimate in Spokane County
What this means for you: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Spokane County averages 7.2 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: 10 mph Summer: 7 mph
Fall: 9 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
4.8/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (267 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Spokane County
How much water you can collect, when to collect it, and what size system you need for your garden.
The practical takeaway: A gravity-fed rain barrel ($75) is the easy entry. A larger cistern ($500-1500) covers a whole growing season. Spokane County's 20" annual rainfall determines whether the larger system is overkill or essential.
Annual Collection
10,167 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 2,250 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Jan, Feb, Nov, Dec
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jun, Jul, Aug, Sep
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 20.4 inches of rain per year
- A 1,000 sq ft roof can collect roughly 10,167 gallons annually
- Rainwater harvesting is fully legal in your state
- Stock up on stored water before your dry season (Jun, Jul, Aug)
- Use a first-flush diverter to keep roof debris out of your collection
