  1. Indoor seed-starting week for basil, cucumber, and kale

    These need a head start before your last frost (May 6). Sow into cells now so you're ready to transplant in a few weeks.

  2. Pick carrots, lettuce, and radish

    The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.

Monthly Watering Calendar for Hanson County

When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.

Why it matters: A drip irrigation system pays for itself in 1-2 seasons in any climate. Hanson County's 28" annual rainfall determines whether you'll run it weekly (dry zones) or maybe just during summer dry spells (wet zones).

Frost Risk Probability

Based on 31 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant May 6 → Oct 5 152 frost-free days Protect crops frost returns Apr May Jun Jul Aug Sep Oct Nov Safe: May 16 Protect by: Oct 15

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) May 16 Oct 15 152 days
Cautious May 12 Oct 9 150 days

Aggressive (risky) Apr 17 Sep 20 156 days
📊
How predictable are frost dates here?

Not very — frost dates can vary by ±29 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

⚠️
Is the growing season changing?

Yes — growing seasons are getting shorter here (about 1.9 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Hanson County

Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.

For new gardeners: The longest day at Hanson County'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.

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 Hanson County

Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.

Why it matters: Mulched soil swings less. The mulch insulates against both winter cold and summer heat. In Hanson County, an aggressive mulch program shifts your effective soil temperature curve toward optimal for most crops.

Plant Warm Crops When

Soil reaches 60°F+

Soil warm enough from Jun through Sep.

Best Month to Compost

Active Composting

Pest & Disease Pressure in Hanson County

Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.

For new gardeners: Two gardeners can grow identical seeds and get wildly different results based on pest pressure alone. Hanson County's climate sets a floor on what's possible without intervention.

Insect Pest Pressure

5.1 / 10

Moderate — common pests appear but manageable with monitoring.

Disease Risk

1.9 / 10

Low disease risk — dry conditions reduce fungal problems.

  • Encourage beneficial insects with flowering herbs like dill, fennel, and yarrow

Cover Crops for Hanson County

Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.

Why this 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 (2 options) — Build soil before the main growing season
Crop Plant By Terminate N-Fixing Soil Benefit
Buckwheat May 12 Aug 3 Rapid growth, attracts pollinators, suppresses weeds
White clover Apr 9 Jul 27 ✓ 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 21 Sep 14 Deep roots break compaction, attract pollinators and beneficial insects
Fall Cover Crops (5 options) — Plant after harvest to protect soil over winter
Crop Plant By Terminate N-Fixing Soil Benefit
Daikon radish Aug 19 Apr 15 Deep taproot breaks compaction, excellent for clay soils
Hairy vetch Jul 19 Apr 15 ✓ Yes Excellent nitrogen fixer, good for depleted soils
Oats Aug 22 Apr 22 Quick biomass, winterkills in cold zones — no spring tillage needed
Winter rye Jul 6 Apr 15 Suppresses weeds, prevents erosion, breaks up compacted soil
Winter wheat Jul 6 Apr 22 Erosion control, weed suppression, good biomass

Wind & Microclimate in Hanson County

Why this matters: A 10 mph wind doesn't feel like much, but it triples leaf transpiration vs. still air. Hanson County's 11.7 mph average means most days are gentle on plants, but consider how a 20+ mph spring gust would affect a flat of seedlings hardened off too quickly.

Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Seasonal Wind Speed

Spring: 16 mph   Summer: 12 mph

Fall: 13 mph   Winter: 15 mph

Prevailing wind: S. Windy area — plant a windbreak hedge on the S side of your garden.

Windbreak Benefit

6.9/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Low

Relatively flat terrain (354 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting in Hanson County

How much water you can collect, when to collect it, and what size system you need for your garden.

Why this matters: Most gardens use 0.5-1 gallon per square foot per week in summer. Hanson County's 28" annual rainfall is enough to cover most needs if you can capture it. Rain barrels under downspouts are the simplest entry point.

Annual Collection

14,154 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 2,000 gal tank.

Legal Status

Unrestricted

Rainwater harvesting is fully legal in your state with no restrictions.

Best Collection Months

May, Jun, Jul, Aug

Highest rainfall months — your barrels will fill up quickly during these months.

Months to Draw From Storage

Jan, 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 28.4 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 14,154 gallons annually
  • Rainwater harvesting is fully legal in your state
  • Stock up on stored water before your dry season (Jan, Feb, Dec)
  • Use a first-flush diverter to keep roof debris out of your collection
