-
It's harvest week for basil, carrots, and cucumber
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.

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) | Apr 21 | Nov 11 | 204 days |
| Cautious | Apr 13 | Oct 31 | 201 days |
| Average year | Apr 6 | Oct 27 | 204 days |
| Optimistic | Mar 31 | Oct 20 | 203 days |
| Aggressive (risky) | Mar 21 | Oct 13 | 206 days |
Not very — frost dates can vary by ±31 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 Miller County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: Day length is the trigger that tells lettuce, spinach, and cilantro to bolt. In Miller County, knowing when that day-length threshold arrives helps you plant a final round in time to harvest before it bolts.

Summer solstice daylight
Shortest Day

Peak Sun Hours
9.7 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 Miller County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
What this means for you: Soil temperature is a leading indicator. A black plastic mulch can warm soil 5-10°F faster than bare ground — meaningful in Miller County's spring if you're trying to plant tomatoes earlier.

Pest & Disease Pressure in Miller County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Quick context: The most successful gardeners in high-pressure regions don't spray more — they design around the problem. Crop rotation, companion planting, and resistant varieties beat reactive spraying.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.
Seasonal Risk

| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | Moderate | Apr, May, Jun, Jul, Aug, Sep |
| Japanese beetles | Moderate | Jun, Jul, Aug |

Organic pest management tips
- Use row covers on susceptible crops during peak pest months
- Apply neem oil preventatively every 7-14 days during active pest season
- Interplant with strong-scented herbs (basil, marigold) to confuse pests
- Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
- Practice crop rotation — never plant the same family in the same spot within 3 years
Cover Crops for Miller County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Quick context: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Miller County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Apr 10 | Aug 25 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Miller County
The practical takeaway: Why care about wind? Above about 10 mph, evaporation jumps and pollinators struggle to land on flowers. Miller County's 8.6 mph average means you can plant tall crops without much support, but it doesn't mean ignore wind — a 20+ mph storm still snaps unstaked tomatoes.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 13 mph Summer: 9 mph
Fall: 9 mph Winter: 11 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
4.7/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (184 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Miller County
How much water you can collect, when to collect it, and what size system you need for your garden.
