Frost Risk Probability

Based on 31 years of NOAA weather station data from 2 stations

Too early frost risk Safe to Plant Mar 5 → Nov 20 260 frost-free days Protect crops frost returns Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Mar 27 Protect by: Dec 12

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) Mar 27 Dec 12 260 days
Cautious Mar 14 Nov 28 259 days
Average year Mar 5 Nov 20 260 days

Organic pest management tips
  • Install physical barriers: floating row covers, copper tape for slugs, mesh netting
  • Apply Bt (Bacillus thuringiensis) for caterpillar control — safe for beneficial insects
  • Use kaolin clay spray to deter a wide range of insects on fruiting crops
  • Release beneficial insects: ladybugs for aphids, parasitic wasps for caterpillars
  • Apply neem oil weekly during high-pressure months
  • Mulch heavily (3-4 inches) to reduce soil-borne disease splash

Wind & Microclimate

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

Seasonal Wind Speed

Spring: 9 mph   Summer: 8 mph

Fall: 11 mph   Winter: 11 mph

Prevailing wind: E. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

4.5/10

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

Frost Pocket Risk

Low

Relatively flat terrain (48 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting Potential

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

Annual Collection

25,219 gal

Per 1,000 sq ft of roof area (at 80% collection efficiency)

6 rain barrels (55 gal each)

For a typical 500 sq ft garden. Serious collectors: consider a 1,250 gal tank.

Legal Status

Unrestricted

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

Best Collection Months

Jun, Jul, Aug, Sep

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

Months to Draw From Storage

Jan, Nov, 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 50.6 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 25,219 gallons annually
