Frost Risk Probability

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

Too early frost risk Safe to Plant Mar 11 → Nov 17 251 frost-free days Protect crops frost returns Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Apr 7 Protect by: Dec 11

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 7 Dec 11 248 days
Cautious Mar 22 Nov 28 251 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.

Daylight hours (sunrise to sunset) Peak sun hours (direct sunlight after cloud cover) ▪ Gold zone = long day (14+ hr) ▪ Blue zone = short day (<12 hr)

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
