Frost Risk Probability

Based on 20 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant Jan 22 → Dec 20 333 frost-free days Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Feb 18 Protect by: Dec 24

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) Feb 18 Dec 24 309 days
Cautious Feb 4 Dec 23 322 days
Average year Jan 22 Dec 20 332 days
Optimistic Jan 12 Dec 12 334 days
Aggressive (risky) Jan 5 Dec 6 335 days

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 shorter days favor short-day onion varieties like Vidalia, Texas 1015, and Red Creole. Plant in fall for best results.

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: 12 mph   Summer: 10 mph

Fall: 11 mph   Winter: 14 mph

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

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

Low

Relatively flat terrain (21 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.

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.
