Top priorities for Benewah County, Idaho gardeners in June
June is a pivotal month for Benewah County, Idaho gardens. Focus on these tasks first and you'll set up the rest of the season for success.
-
Get basil, cucumber, and kale seeds going inside
You're about 14 weeks out from your last frost — the perfect window to get these germinating indoors.
-
Basket week: carrots, lettuce, and radish
Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
Looking ahead to July
- Starting indoors: peppers, pole beans, and tomatoes
- First harvests: basil, carrots, and cucumber
- Fall sowing: carrots, kale, and lettuce
Plummer has a classic four-season growing climate (Zone 6b). The last spring frost typically lands around May 8 and the first fall frost arrives around October 1 — a 146-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.
Plummer averages 25.2 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 Plummer
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Quick context: Over-watering kills more plants than under-watering. Plummer's 0" annual rainfall changes the gardening playbook — humid-region gardeners often water by the calendar when they should water by the soil moisture.

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 6 | Oct 25 | 141 days |
| Cautious | May 14 | Oct 9 | 148 days |
| Average year | May 8 | Oct 1 | 146 days |
| Optimistic | Apr 29 | Sep 20 | 144 days |
| Aggressive (risky) | Apr 16 | Sep 8 | 145 days |
Not very — frost dates can vary by ±51 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 2.2 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Plummer
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: You can't change the sun. Picking the right day-length-matched varieties for Plummer matters more than any other "fix" you make — and the seed packet tells you (look for "long-day," "short-day," "day-neutral").
Longest Day
15.7 hours
Summer solstice daylight
Shortest Day
8.3 hours
Winter solstice daylight
Peak Sun Hours
11.6 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 Plummer
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Why this matters: Compost piles need 130-160°F internal temp to actively break down. Below 50°F ambient, microbial activity slows dramatically. Plummer's soil temperature curve also tells you when your compost is working and when it's napping.
Plant Warm Crops When
Soil reaches 60°F+
Soil warm enough from Jul through Aug.
Best Month to Compost

Microbial activity peaks when soil is warm.
Active Composting

Pest & Disease Pressure in Plummer
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
The practical takeaway: 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
Low disease risk — dry conditions reduce fungal problems.
Seasonal Risk

- Practice crop rotation annually to break pest cycles
- Encourage beneficial insects with flowering herbs like dill, fennel, and yarrow
Cover Crops for Plummer
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why it 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 18 | Aug 6 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | May 14 | Aug 6 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Apr 12 | Jul 23 | ✓ 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 25 | Sep 3 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (7 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Austrian winter peas | Jul 30 | Apr 24 | ✓ Yes | Fixes nitrogen, good for heavy clay soils |

| Winter wheat | Jul 9 | Apr 24 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Plummer
Why this matters: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Plummer averages 0.0 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: 11 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
7.3/10
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 2,524 ft of elevation range — cold air pools in low spots. Avoid planting frost-sensitive crops in valleys.
